Pass By Value

Harry Hacker has written the following method that is supposed to swap the contents of two variables:

static void swap(int a, int b){              int temp = a;              a = b;              b = temp;}

However, the statements

int a = 5;int b = 6;swap(a,b);System.out.println("a = " + a + " and b = " + b);

produce the output

a = 5 and b = 6.

Explain why Harry’s method does not work as intended.
