Reference static field after declaration in Java

The static field variable is a class level variable and it belongs to the class not the class object.

So the static field variable is common to all the class objects i.e. a single copy of the static field variable is shared among all the class objects.

A program that demonstrates referencing the static field variable after declaration is given as follows:

Example

 Live Demo

public class Demo {    static int a = 7;    static int b = a + 5;    public static void main(String[] args) {       System.out.println("a = " + a);       System.out.println("b = " + b);    } }

Output

a = 7 b = 12

Now let us understand the above program.

The class Demo contains static variables a and b. The method main() prints the values of a and b. A code snippet which demonstrates this is as follows:

static int a = 7; static int b = a + 5; public static void main(String[] args) {    System.out.println("a = " + a);    System.out.println("b = " + b); }
