    I happened to run into a bit of code in an application I am maintaining using Eclipse Europa and Java 1.5 (Java 5).

    I had a method that I ended up into as I was cleaning up Eclipse warnings.

    Code:
    if (false)
    {
       // some code
    }



    Because you needed to know!


    Code:
     class IfFalseApp
            {
                    public static void main(String[] args)
                    {
                            System.out.println("What Does if(false) do?");
                            if(false)
                            {
                                    System.out.println("if (false) returns true");
                             }
                            else
                            {

                                    System.out.println("if (false) returns false");
                            }
                    }
            }


    C:\Source\HelloWorld>java IfFalseApp
    What Does if(false) do?
    if (false) returns false


    A little search points out that it is a chintzy way to negate or comment out code.
