2.1. Android tizimi uchun Java dasturlash muhiti. Java dasturlash tilining asosiy konstruksiyalari
Java - Obyektga yо‘naltirilgan dasturlash tili bо‘lib, 1991 yilda Sun kompaniyasi tomonidan ishlab chiqarilgan va uning birinchi versiyasi 1995 yilda foydalanuvchilarga taqdim qilingan. Hozirgi kunda 3 ta edition bor:
Java 2 Platform Standard Edition (J2SE)
Java 2 Platform Enterprise Edition (J2EE)
Java 2 Platform Micro Edition (J2ME)
Java application - Dasturiy ilovalar asosan Java tili va uning kutubxonalari orqali yaratiladi, Java applet lar esa HTML bilan birgalikda ishlaydigan kichik hajmdagi dasturlar hisoblanadi. Bunda java fayllar va html fayllar birgalikja mavjud bо‘ladi(~~.java and html files (~~.html )
Java dasturlash tili asoslari
Java tilidagi ma’lumotlar tiplari
О‘zgaruvchilarni e’lon qilish va ularning tiplari
Java modifiers (package, public, private, protected, static, final, abstract, synchronized)
Asosiy operatorlar
Sikl (while, do…while, for) operatorlari
Shart (if, if…else, nested if, nested if…else, switch) operatorlari
Java da sonlar
Simvollar va satrlar bilan ishlash
Massivlar
Metodlar
Fayllar bilan ishlash
Istisnolarni boshqarish
Regular Expression
Yuqorida aytib о‘tilganidek, Java tili tо‘liq obyektga yо‘naltirilgan dasturlash tili bо‘lib, bunda quyidagi tushunchalar asosiy hisoblanadi.
Object – barcha obyektlar holat (states) va harakat (behaviors) dan tashkil topadi. Masalan moshina obyekt bо‘lsa uning holati – rangi, turi, tezligi bо‘lsa, harakati – tezlashish, sekinlashish, tо‘xtash, harakatni boshlash va h.k. lar hisoblanadi;
Class – obyekt uchun kerakli barcha holatlarni о‘zida mujassamlashtirgan shablon;
Methods – obyektning harakatini (behaviors) ta’minlovchi kodlar blokidir. Sinf bir nechta metoddan iborat bо‘lishi mumkin. Har bir metod orqali obyekt harakati uchun kerakli bо‘lgan barcha jarayonlar mantiqiy ketma-ketligi (ma’lumotlarni yuklash, о‘qish, yozish, bazaga yozish, dastur interfeysini boshqarish va h.k. lar) amalga oshiriladi;
Instance Variables – obyekt murojaat qiluvchi о‘zgaruvchilar.
Java da birinchi dastur
public class MyFirstJavaProgram {
// This is my first java program. This will print 'Hello World' as the output
public static void main(String []args) { System.out.println("Hello World"); // prints Hello World
}
}
