Bugungi kunda axborot-kommunikatsiya sohasini rivojlantirish-ning asosi
hisoblangan dasturiy mahsulotlarni ishlab chiqarish milliy iqtisodiyoti
rivojlanishining muhim sharti sifatida alohida ahamiyat kasb etmoqda.
Hayotimizning har jabhasida faol qo‘llanilayotgan axborot almashinuv
texnologiyalaridan samarali foydalanish ulardagi dasturiy ta’minotlarning o‘ziga
xosligi, ommabopligi va innovatsion yangiligiga bog‘liq. “Axborotlashtirish
to‘g‘risida”gi, “Telekommuni-katsiyalar to‘g‘risida”gi, “EHM dasturlari va
ma’lumotlar bazasini himoya qilish to‘g‘risida”gi qonunlar soha rivojida muhim
ahamiyat kasb etmoqda. Bugun yurtimizda axborot-kommunikatsiya
texnologiyalari kirib bormagan sohaning o‘zi yo‘q. Bu esa, o‘z navbatida, softver
sanoatining izchil rivojlanishiga keng yo‘l ochmoqda. Xususan, hozirgi kunda
mamlakatimizda dasturiy mahsulotlarni yaratish, ishlab chiqarish va joriy qilish
bilan shug‘ullanuvchi 260 dan ziyod tadbirkorlik sub’ektlari faoliyat yuritmoqda.
Mamlakatimizda dasturiy ta’minot sanoatini shakllantirish va rivojlantirish
uchun zarur shart-sharoitlar, sohaga daxldor mustahkam qonunchilik bazasini
yaratishga e’tibor qaratilmoqda. Hozirgacha 10 dan ziyod qonun, Prezident va
Vazirlar Mahka-masining qator farmon hamda qarorlari qabul qilindi.
Dasturchilarni qo‘llab-quvvatlash borasida muntazam chora-tadbirlar amalga
oshirilayotir.Prezidentimiz tomonidan joriy yilning 20 sentyabrida imzolangan
“Mamlakatimizning dasturiy ta’minot vositalari ishlab chiquvchilarini
rag‘batlantirishni yanada kuchaytirish chora-tadbirlari to‘g‘risida”gi qarori bu
yo‘ldagi navbatdagi muhim qadam bo‘ldi.
Hozirda davlat hokimiyati va boshqaruvi organlari dasturiy mahsulotlarning
faol iste’molchisi hisoblanadi. Keyingi vaqtda mamlakatimizda vazirlik va
idoralar, xo‘jalik birlashmalari, yirik korxonalarning xarajat smetasi va biznes
rejalarida ishlab chiqarish jarayonlarini avtomatlashtirish, axborot tizimlari va
resurslarini yaratish, dasturiy mahsulotlar hamda interfaol davlat xizmatlarini joriy
etishga qaratilgan xarajatlarni nazarda tutish yuzasidan tegishli ishlar olib
2

borilmoqda. Joriy yildan e’tiboran davlat hokimiyati va boshqaruvi organlarining
idoralararo integratsiyalashgan axborot tizimlarini joriy etish, idoralararo
ma’lumotlar uzatish tarmoqlarini yaratish, “Elektron hukumat” tizimini hamda
internet tarmog‘ining milliy segmentini shakllantirish bo‘yicha loyihalarni
ro‘yobga chiqarish uchun davlat buyurtmasini shakllantirish va moliyalashtirish
borasidagi ishlar boshlab yuborilgan. Mazkur hujjat dasturiy ta’minot sanoatini
rivojlantirish, davlat organlarida ixtisoslashtirilgan dasturiy mahsulotlardan
foydalanishni tartibga soluvchi me’yoriy-huquqiy bazani yanada takomillashtirish,
“Elektron hukumat” loyihasini amalga oshirishda mahalliy kompaniyalarning faol
ishtirokini rag‘batlantiradi.
2006 yildan buyon “Best Soft Uzbekistan” dasturiy mahsulotlar ko‘rgazmasi
tashkil etib kelinmoqda. Milliy dasturiy mahsulotlar ko‘rgazmasida sohada
erishilgan muvaffaqiyatlar namoyish etilib, mahorat darslari, taqdimotlar va ta’lim
seminarlarida respublikadagi soft industriyaning dolzarb loyihalari va istiqbollari
sohasining yetakchi mutaxassislari ishtirokida muhokama qilinadi. Ko‘rgazmada
xalqaro va mahalliy kompaniya — dasturiy mahsulotlarni ishlab chiqaruvchilar
hamda integratorlar, kontent-ishlab chiqaruvchilar, provayderlar, ilmiy va ta’lim
muassasalari, vazirliklar, idoralar vakillari ham ishtirok etishadi.

I. Nazariy qism
1.1. Java dasturi haqida.
Java dasturlash tili Oak dasturlash tili asosida paydo bo ldi. Oak dasturlashʻ
tili 90-yillarning boshida Sun Microsystems tomonidan platformaga, ya ni
ʼ
operatsion sistemaga bog liq bo lmagan holda ishlovchi yangi avlod aqlli
ʻ ʻ
qurilmalarini yaratishni maqsad qilib harakat boshlagan edi. Bunga erishish uchun
Sun xodimlari C++ni ishlatishni rejalashtirdilar, lekin ba zi sabablarga ko ra bu
ʼ ʻ
fikridan voz kechishdi. Oak muvofaqiyatsiz chiqdi va 1995-yilda Sun uning
nomini Java ga almashtirdi va uni WWW rivojlanishiga xizmat qilishi uc hun
ma lum o zgarishlar qilishdi.
ʼ ʻ
Java obyektga yo naltirilgan dasturlash
ʻ ( inglizcha : OOP — Object Oriented
Programming ) tili va u C++ ga ancha o xshash. Eng ko p yo l qo yildigan
ʻ ʻ ʻ ʻ
xatolarga sabab bo luvchi qismlari olib tashlanib, Java dasturlash tili ancha
ʻ
soddalashtirildi.
Java kod yozilgan fayllar ( *.java bilan nihoyalanuvchi) kompilatsiyadan
keyin bayt kod ( inglizcha : bytecode ) ga o tadi va bu bayt kod
ʻ Java Virtual
Mashinasi JVM tomonidan o qib yurgizdiriladi.
ʻ
Java afzalliklari:
 WORA — ( inglizcha : Write
Once, Run Anywhere - portable). Platforma
tanlamaydi;
 xavfsizlik (ishonch yo q kodni xavfsiz ishga tushirish);
ʻ
 xotirani xavfsiz boshqarish (avtomat ravishda chiqindilarni yig adi);
ʻ
 tarmoq uchun dasturlar yozish ;
 ko p oqimli (
ʻ inglizcha : Multi-thread ) dasturlash;
 dinamik & kengaytirish;
Class lar alohida fayllarda saqlanadi. Kerak bo lsa ishlatiladi. Dinamik ravishda
ʻ
imkoniyatini oshirish xam mumkin kerak bo lsa.
ʻ
Java SE (inglizcha: Java Standart Edition) — serverda, shaxsiy kompyuterda
desktoplarda ishlovchi dasturlar, appletlar yaratish uchun ishlatiladi. Bu

texnologiya yordamida yaratilgan dasturlar deyarli barcha operatsion tizimlarda
ishlay oladi (Windows NT, Macintosh, Linux va Solaris). Shu bilan birga JavaSE
boshqa Java turlarining asosi hisoblanadi.
JVM (Java Virtual mashinasi) JVM ning vazifasi tarjimonlik ya’ni, dastlab biz
yozgan *.java fayl kompilyator yordamida bayt kod ga o’giriladi va JVM
yordamida esa mashina tiliga aylantiriladi. Bu degani JVM qaysi platformaga
tegishli bo’lsa, kodlarni ham o’sha platformaga moslab beradi. JVM ni ko’pgina
qurilmalar va dasturiy ta’minotlar uchun ishlatish mumkin. Har bir OT(operatsion
tizim) uchun JVM JRE va JDK lar konfiguratsiyasi farq qiladi, chunki bular
platformaga bog’liq. Lekin java mustaqil platforma hisoblanadi.
JVM ning amalga oshiradigan asosiy vazifalari
Loads code (kod yuklanishi)
Verifies code (kod tekshirilishi)
Executes code (kod bajarilishi)
Provides runtime environment (dasturni bajarilish muhitini ta’minlash)
JRE (Java bajarilish muhiti)
JRE – Java Runtime Environment
JRE – bu faqat dastur bajarilishi uchun kerak bo`lgan muhit xolos. Dasturchi
bo`lmagan oddiy foydalanuvchilarga Java dasturlari bajarilishi uchun JRE
yetarlidir.
JDK(Java Development Kid) - JDK tarkibida JRE va boshqa qo'shimcha
dasturlash uskunalari bo'ladi

1.2. Android studio ishchi oynasi.
1-rasm
Android Studio nomidan ham malumki bu Android OS da ishlovchi
qurilmalarga dastur tuzishda kerak bo‘ladigan kompyuter dasturi. IT gegantlaridan
hisoblanmush Google kompaniyasiga tegishli bo‘lib Android Dasturchilarga
android dastur yaratishda yeng ko‘p qullaniladigan dastur Play Store bozoridagi
50% idan ko‘p android dasturlar aynan manashu dastur yordamida yaratilgan .
Android Studioda Java, Kotlin, Xml dasturlash tillari yordamida istalgan
android dasturni yaratish mumkin faqatgina yuqoridagi tillarni bilgan holda,
shaxsan mening o‘zim Java dasturlash tilidan foydalangan xolda android dastur
yarataman.

II. Asosiy qism
2.1 Android Studioda fonlarni joylshtirish.
Avvalo android studioda yangi proekt yaratamiz.
Empty Views Activity qismini tanlab Next tugmasini bosamiz.
11

Android Studio turli xil vaziyatlar uchun bir qator shablonlarni taqdim etadi,
ammo eng keng tarqalgani Basic Activity va Empty Activity. Bu ko’plab
dasturlami yaratish uchun eng qulay start-up shablonlari. Endi boshlang'ich holat
bo'yicha Empty Activity shabloni tanlanadi (agar tanlanmagan bo'lsa, uni tanlang)
va Next tugmasini bosing. Shundan so'ng, yangi loyiha sozlamalari oynasi
ko'rsatiladi
Name joyiga proekt nomini yozamiz. Language degan joyiga kotlin yoki
javani tanlaymiz. Men javada ishlayman.
Yangi loyihani yaratish oynasida biz uning dastlabki sozlamalarini
o'rnatamiz:
> llova nomi Name maydoniga kiritiladi. HelloApp ismini nom sifatida ko’rsating.
> Package Name maydoni asosiy dastur sinfini joylashtiradigan paket nomini
belgilaydi. Bunday holda, test loyihalari uchun bu qiymat juda muhim emas,
shuning uchun com.example.helloapp-ni o’mating.
> Save Location maydoni qattiq diskdagi loyiha fayllarining joylashishini
belgilaydi. Boshlang'ich holatbo'yicha qoldirishimiz mumkin.
12

> Language maydonida biz Java dasturlash tili sifatida ko'rsatamiz (ehtiyot bo'Iing,
chunki boshlang'ich holat bo’yicha ushbu maydonda Kotlin dasturlash tili mavjud)
> Minimum SDK maydoni eng kichik qo'llab-quwatlanadigan SDK versiyasini
belgilaydi. Standart - API 21: Android 5.0 (Lollipop) ni tark etamiz, demak
bizning dasturimiz Android 5.0 dan boshlab ishga tushirilishi mumkin, ya'ni 94%
qurilmalar. Eski qurilmalar ishlay oimaydi. Shuni esda tutish kerakki, SDK
versiyasi qanchalik yuqori bo'lsa, qo’llabquwatlanadigan qurilmalar diapazoni
shunchalik kichik bo'ladi. Keyin Finish tugmachasini bosing va Android Studio
yangi loyihani yaratadi:
Loyihamda quyidagicha fayllar bor:

KIRISH Bugungi kunda axborot-kommunikatsiya sohasini rivojlantirish-ning asosi hisoblangan dasturiy mahsulotlarni ishlab chiqarish milliy iqtisodiyoti rivojlanishining muhim sharti sifatida alohida ahamiyat kasb etmoqda. Hayotimizning har jabhasida faol qo‘llanilayotgan axborot almashinuv texnologiyalaridan samarali foydalanish ulardagi dasturiy ta’minotlarning o‘ziga xosligi, ommabopligi va innovatsion yangiligiga bog‘liq. “Axborotlashtirish to‘g‘risida”gi, “Telekommuni-katsiyalar to‘g‘risida”gi, “EHM dasturlari va ma’lumotlar bazasini himoya qilish to‘g‘risida”gi qonunlar soha rivojida muhim ahamiyat kasb etmoqda. Bugun yurtimizda axborot-kommunikatsiya texnologiyalari kirib bormagan sohaning o‘zi yo‘q. Bu esa, o‘z navbatida, softver sanoatining izchil rivojlanishiga keng yo‘l ochmoqda. Xususan, hozirgi kunda mamlakatimizda dasturiy mahsulotlarni yaratish, ishlab chiqarish va joriy qilish bilan shug‘ullanuvchi 260 dan ziyod tadbirkorlik sub’ektlari faoliyat yuritmoqda. Mamlakatimizda dasturiy ta’minot sanoatini shakllantirish va rivojlantirish uchun zarur shart-sharoitlar, sohaga daxldor mustahkam qonunchilik bazasini yaratishga e’tibor qaratilmoqda. Hozirgacha 10 dan ziyod qonun, Prezident va Vazirlar Mahka-masining qator farmon hamda qarorlari qabul qilindi. Dasturchilarni qo‘llab-quvvatlash borasida muntazam chora-tadbirlar amalga oshirilayotir.Prezidentimiz tomonidan joriy yilning 20 sentyabrida imzolangan “Mamlakatimizning dasturiy ta’minot vositalari ishlab chiquvchilarini rag‘batlantirishni yanada kuchaytirish chora-tadbirlari to‘g‘risida”gi qarori bu yo‘ldagi navbatdagi muhim qadam bo‘ldi. Hozirda davlat hokimiyati va boshqaruvi organlari dasturiy mahsulotlarning faol iste’molchisi hisoblanadi. Keyingi vaqtda mamlakatimizda vazirlik va idoralar, xo‘jalik birlashmalari, yirik korxonalarning xarajat smetasi va biznes rejalarida ishlab chiqarish jarayonlarini avtomatlashtirish, axborot tizimlari va resurslarini yaratish, dasturiy mahsulotlar hamda interfaol davlat xizmatlarini joriy etishga qaratilgan xarajatlarni nazarda tutish yuzasidan tegishli ishlar olib 2

borilmoqda. Joriy yildan e’tiboran davlat hokimiyati va boshqaruvi organlarining idoralararo integratsiyalashgan axborot tizimlarini joriy etish, idoralararo ma’lumotlar uzatish tarmoqlarini yaratish, “Elektron hukumat” tizimini hamda internet tarmog‘ining milliy segmentini shakllantirish bo‘yicha loyihalarni ro‘yobga chiqarish uchun davlat buyurtmasini shakllantirish va moliyalashtirish borasidagi ishlar boshlab yuborilgan. Mazkur hujjat dasturiy ta’minot sanoatini rivojlantirish, davlat organlarida ixtisoslashtirilgan dasturiy mahsulotlardan foydalanishni tartibga soluvchi me’yoriy-huquqiy bazani yanada takomillashtirish, “Elektron hukumat” loyihasini amalga oshirishda mahalliy kompaniyalarning faol ishtirokini rag‘batlantiradi. 2006 yildan buyon “Best Soft Uzbekistan” dasturiy mahsulotlar ko‘rgazmasi tashkil etib kelinmoqda. Milliy dasturiy mahsulotlar ko‘rgazmasida sohada erishilgan muvaffaqiyatlar namoyish etilib, mahorat darslari, taqdimotlar va ta’lim seminarlarida respublikadagi soft industriyaning dolzarb loyihalari va istiqbollari sohasining yetakchi mutaxassislari ishtirokida muhokama qilinadi. Ko‘rgazmada xalqaro va mahalliy kompaniya — dasturiy mahsulotlarni ishlab chiqaruvchilar hamda integratorlar, kontent-ishlab chiqaruvchilar, provayderlar, ilmiy va ta’lim muassasalari, vazirliklar, idoralar vakillari ham ishtirok etishadi. 3

I. Nazariy qism 1.1. Java dasturi haqida. Java dasturlash tili Oak dasturlash tili asosida paydo bo ldi. Oak dasturlashʻ tili 90-yillarning boshida Sun Microsystems tomonidan platformaga, ya ni ʼ operatsion sistemaga bog liq bo lmagan holda ishlovchi yangi avlod aqlli ʻ ʻ qurilmalarini yaratishni maqsad qilib harakat boshlagan edi. Bunga erishish uchun Sun xodimlari C++ni ishlatishni rejalashtirdilar, lekin ba zi sabablarga ko ra bu ʼ ʻ fikridan voz kechishdi. Oak muvofaqiyatsiz chiqdi va 1995-yilda Sun uning nomini Java ga almashtirdi va uni WWW rivojlanishiga xizmat qilishi uc hun ma lum o zgarishlar qilishdi. ʼ ʻ Java obyektga yo naltirilgan dasturlash ʻ ( inglizcha : OOP — Object Oriented Programming ) tili va u C++ ga ancha o xshash. Eng ko p yo l qo yildigan ʻ ʻ ʻ ʻ xatolarga sabab bo luvchi qismlari olib tashlanib, Java dasturlash tili ancha ʻ soddalashtirildi. Java kod yozilgan fayllar ( *.java bilan nihoyalanuvchi) kompilatsiyadan keyin bayt kod ( inglizcha : bytecode ) ga o tadi va bu bayt kod ʻ Java Virtual Mashinasi JVM tomonidan o qib yurgizdiriladi. ʻ Java afzalliklari:  WORA — ( inglizcha : Write Once, Run Anywhere - portable). Platforma tanlamaydi;  xavfsizlik (ishonch yo q kodni xavfsiz ishga tushirish); ʻ  xotirani xavfsiz boshqarish (avtomat ravishda chiqindilarni yig adi); ʻ  tarmoq uchun dasturlar yozish ;  ko p oqimli ( ʻ inglizcha : Multi-thread ) dasturlash;  dinamik & kengaytirish; Class lar alohida fayllarda saqlanadi. Kerak bo lsa ishlatiladi. Dinamik ravishda ʻ imkoniyatini oshirish xam mumkin kerak bo lsa. ʻ Java SE (inglizcha: Java Standart Edition) — serverda, shaxsiy kompyuterda desktoplarda ishlovchi dasturlar, appletlar yaratish uchun ishlatiladi. Bu 4

texnologiya yordamida yaratilgan dasturlar deyarli barcha operatsion tizimlarda ishlay oladi (Windows NT, Macintosh, Linux va Solaris). Shu bilan birga JavaSE boshqa Java turlarining asosi hisoblanadi. JVM (Java Virtual mashinasi) JVM ning vazifasi tarjimonlik ya’ni, dastlab biz yozgan *.java fayl kompilyator yordamida bayt kod ga o’giriladi va JVM yordamida esa mashina tiliga aylantiriladi. Bu degani JVM qaysi platformaga tegishli bo’lsa, kodlarni ham o’sha platformaga moslab beradi. JVM ni ko’pgina qurilmalar va dasturiy ta’minotlar uchun ishlatish mumkin. Har bir OT(operatsion tizim) uchun JVM JRE va JDK lar konfiguratsiyasi farq qiladi, chunki bular platformaga bog’liq. Lekin java mustaqil platforma hisoblanadi. JVM ning amalga oshiradigan asosiy vazifalari Loads code (kod yuklanishi) Verifies code (kod tekshirilishi) Executes code (kod bajarilishi) Provides runtime environment (dasturni bajarilish muhitini ta’minlash) JRE (Java bajarilish muhiti) JRE – Java Runtime Environment JRE – bu faqat dastur bajarilishi uchun kerak bo`lgan muhit xolos. Dasturchi bo`lmagan oddiy foydalanuvchilarga Java dasturlari bajarilishi uchun JRE yetarlidir. JDK(Java Development Kid) - JDK tarkibida JRE va boshqa qo'shimcha dasturlash uskunalari bo'ladi 5
