Chapter 5, Problem 14RE

Consider the following method that is intended to swap the values of two integers:

 public static void falseSwap(int a, int b)

 {

 int temp = a;

 a = b;

 b = temp;

 }

 public static void main(String[] args)

 {

 int x = 3;

 int y = 4;

 falseSwap(x, y);

 System.out.println(x + " " + y);

 }

Why doesn’t the falseSwap method swap the contents of x and y?
