static Keyword

title: static Keyword in Java description: static variable, method, block aur class

static members class ke hote hain, kisi specific object ke nahi.

Static Variable

class Counter { static int count = 0; // Sabhi objects share karte hain Counter() { count++; } } Counter c1 = new Counter(); Counter c2 = new Counter(); System.out.println(Counter.count); // 2

Static Method

java exampleWoHoTech

class MathUtils {
    static int square(int n) { return n * n; }
    static int cube(int n) { return n * n * n; }
}

// Object banaye bina call karo
MathUtils.square(5); // 25
MathUtils.cube(3);   // 27

Static Block

Class load hone par ek baar execute hota hai.

java exampleWoHoTech

class Config {
    static String dbUrl;
    static {
        dbUrl = "jdbc:mysql://localhost/mydb";
        System.out.println("Config loaded");
    }
}

Static Nested Class

java exampleWoHoTech

class Outer {
    static class Inner {
        void show() { System.out.println("Static Inner"); }
    }
}
Outer.Inner obj = new Outer.Inner();

Static ke Restrictions

Static method mein this use nahi hota
Static method non-static members directly access nahi kar sakta
Static method override nahi hote (method hiding hoti hai)

Static vs Instance

	Static	Instance
--	--	--
Memory	Class load par	Object creation par
Access	ClassName.member	objectName.member
`this`	Nahi	Haan
