Static Variable in Java

1. Static Variable:

                                A static variable is also called as a Class Variable. The static variable gets memory only once at the time of Class Loading. Normally the static variable is also called as the Class variable.

Example: 





public class HelloWorld{

static int a = 0;

static String b = "";

static double pi = 3.14;

     HelloWorld(int a,String b) {

this.a = a;

this.b = b;

}

public static void main(String[] args) {

double piVal = HelloWorld.pi;//accessing the class variable

System.out.println("Value pi is: "+piVal);

}

}
