Call by value example

Below example will explain how call by value is happening in java.

public class CallByValue {

    private int value = 5;

    private int change(int input) {
        input = input + 10;// changes will be in the local variable only
        return input;
    }

    public static void main(String args[]) {
        CallByValue cv = new CallByValue();

        System.out.println("before change: " + cv.value);
        System.out.println("calling change method directly: " + cv.change(50));
        System.out.println("after change: " + cv.value);
    }
}

Output:

before change: 5
calling change method directly: 60
after change: 5
