Call by value in JAVA

public class Test
{
    public void callByValue(int x)
    {
        x=100;
    }
    public static void main(String[] args)
    {
       int x=50;
        Test t = new Test();
        t.callByValue(x);
        System.out.println(x);
    }    
}

Output is: 50

In the above example, even though the value of X is 100, we are setting local variable as 50 and then calling the "callByValue()" method. So, it will reset the value of x from 100 to 50.

Thus the output is: 50
