Assalomu alaykum bugun siz bilan Java haqida uning mazmuni haqida gaplashib olamiz! Java bu dasturlash tili hisoblanib. Ko’p qo’llanilib kelinayotgan dasturlash tillaridan biri hisoblanadi. Java dasturlash tilida mobile, desktop, web, o’yinlar va ko’pgina imkoniyatlari mavjud.

Java va JavaScript boshqa boshqa dasturlash tili hisoblanadi!

Biz siz bilan hozir Java kodni ko’ramiz! Bu kodga keyinroq kengroq to’xtalib o’tamiz!

public class MyClass public static void main(String[] args) System.out.println("Hello World, MasterSherkulov"); > >

Java – 1995 yilda yaratilgan eng mashxur dasturlash tillaridan biri hisoblanadi. Java dasturlash tili Oracle ga tegishli hisoblanadi.

Java dasturlash tilida nima qila olishimiz mumkin!?

• Mobile ilovalar. Android OT uchun ilovalar yaratish.
• Desktop dasturlar yaratish imkoniyati
• Web Saytlar
• Web serverlar va Dastur Serverlari
• O’yinlar
• Ma’lumotlar bazasiga ulanish

Keyin darsliklarimizda Biz siz bilan Java dasturlash tiliga ko’proq to’xtalib o’tamiz!

Java ishlari

Java talab juda yuqori veb va mobil ilovalarini ishlab chiqish uchun Java dasturchilarni yollashmoqda.Quyida Java-dan foydalanayotgan yirik kompaniyalar va ularga yaxshi Java dasturchilari kerak:

Java bir marta yoziladi, istalgan joyda ishga tushiriladi.

• Ob’ektga yo’naltirilgan – Java-da hamma narsa ob’ektdir. Java osongina kengaytirilishi mumkin, chunki u Ob’ekt modeliga asoslangan.
• Platformadan mustaqil – C va C++ kabi ko’plab boshqa dasturlash tillaridan farqli o’laroq, Java kompilyatsiya qilinganda, u platformaga xos mashinaga emas, balki platformadan mustaqil bayt kodiga kompilyatsiya qilinadi. Ushbu bayt kodi internet orqali tarqatiladi va qaysi platformada ishlayotgan bo’lishidan qat’i nazar Virtual Mashina (JVM) tomonidan talqin qilinadi.
• Oddiy – Java o’rganish oson bo’lishi uchun yaratilgan. Agar siz Java OOP ning asosiy tushunchasini tushunsangiz, uni o’zlashtirish oson bo’ladi.
• Xavfsiz – Java-ning xavfsiz xususiyati bilan u virussiz, buzg’unchiliksiz tizimlarni ishlab chiqish imkonini beradi. Autentifikatsiya usullari ochiq kalitlarni shifrlashga asoslangan.
• Arxitektura-neytral – Java kompilyatori arxitektura-neytral ob’ekt fayl formatini yaratadi, bu esa kompilyatsiya qilingan kodni Java ish vaqti tizimining mavjudligi bilan ko’plab protsessorlarda bajariladigan qiladi.
• Portativ – arxitektura-neytral bo’lish va spetsifikatsiyaning amalga oshirishga bog’liq jihatlari yo’qligi Java-ni portativ qiladi. Java-dagi kompilyator ANSI C-da POSIX kichik to’plami bo’lgan toza portativlik chegarasi bilan yozilgan.
• Mustahkam − Java asosan kompilyatsiya vaqtidagi xatolarni tekshirish va ish vaqtini tekshirishga e’tibor qaratib, xatolarga moyil vaziyatlarni bartaraf etishga harakat qiladi.
• Multithreaded – Java-ning ko’p tarmoqli xususiyati bilan bir vaqtning o’zida bir nechta vazifalarni bajara oladigan dasturlarni yozish mumkin. Ushbu dizayn xususiyati ishlab chiquvchilarga muammosiz ishlashi mumkin bo’lgan interaktiv ilovalarni yaratishga imkon beradi.
• Interpreted – Java bayt kodi tezda mahalliy mashina ko’rsatmalariga tarjima qilinadi va hech qanday joyda saqlanmaydi. Rivojlanish jarayoni tezroq va analitikdir, chunki ulanish bosqichma-bosqich va engil jarayondir.
• Yuqori unumdorlik – Just-In-Time kompilyatorlaridan foydalangan holda Java yuqori ishlash imkonini beradi.
• Taqsimlangan – Java Internetning taqsimlangan muhiti uchun mo’ljallangan.
• Dinamik – Java C yoki C++ ga qaraganda dinamikroq hisoblanadi, chunki u rivojlanayotgan muhitga moslashish uchun mo’ljallangan. Java dasturlari ish vaqtida ob’ektlarga kirishni tekshirish va hal qilish uchun ishlatilishi mumkin bo’lgan keng ko’lamli ish vaqti ma’lumotlarini olib yurishi mumkin.

Sizga kerak bo’ladigan qurilma

Ushbu qo’llanmada ko’rib chiqilgan misollarni bajarish uchun sizga kamida 128 MB operativ xotiraga ega 300 MGts chastotali Pentium kompyuter kerak bo’ladi (256 MB RAM tavsiya etiladi).

Shuningdek, sizga quyidagi dasturlar kerak bo’ladi –

• Linux 7.1 yoki Windows xp/7/8 operatsion tizimi
• Java JDK 8
• Microsoft Notepad yoki boshqa matn muharriri

Ushbu qo’llanma Java-dan foydalangan holda GUI, tarmoq va veb-ilovalarni yaratish uchun kerakli ko’nikmalarni beradi.
