Java Program to Demonstrate the Passed by Value

Here is a Java Program to Demonstrate the Passed by Value

class Test {
  void meth(int i, int j) {
    i *= 2;
    j /= 2;
  }
}

This is a Main Class to run Above Java Class.

class CallByValue {
  public static void main(String args[]) {
    Test ob = new Test();
    int a = 15, b = 20;
    
    System.out.println("a and b before call: " +
                       a + " " + b);

    ob.meth(a, b); 

    System.out.println("a and b after call: " +
                       a + " " + b);
  }
}

Output of Above Java Program
a and b before call: 15 20
a and b after call: 15 20
