Consider the following method that is intended to swap the values of two floating point
numbers:
public static void falseSwap(double a, double b)
{
double temp = a;
a = b;
b = temp;
}
public static void main(String[] args)
{
double x = 3;
double y = 4;
falseSwap(x, y);
System.out.println(x + " " + y);
}
Why doesn’t the method swap the contents of x and y?
