An example that shows the behavior of value parameters In Java

public class PrimitiveParameters
{ 
 public static void main(String[] args)
 { go();
 }
 
 public static void go()
 { int x = 3;
  int y = 2;
  System.out.println("In method go. x: " + x + " y: " + y);
  falseSwap(x,y);
  System.out.println("in method go. x: " + x + " y: " + y);
  moreParameters(x,y);
  System.out.println("in method go. x: " + x + " y: " + y);
 }
 
 public static void falseSwap(int x, int y)
 { System.out.println("in method falseSwap. x: " + x + " y: " + y);
  int temp = x;
  x = y;
  y = temp;
  System.out.println("in method falseSwap. x: " + x + " y: " + y);
 }
 
 public static void moreParameters(int a, int b)
 { System.out.println("in method moreParameters. a: " + a + " b: " + b);
  a = a * b;
  b = 12;
  System.out.println("in method moreParameters. a: " + a + " b: " + b);
  falseSwap(b,a);
  System.out.println("in method moreParameters. a: " + a + " b: " + b); 
 }
}
