Question

I need to change the java API to make say assassinscreed.out.println to work the same way as system.out.println..

Can u pls shed some light on it..?

Answer 1

Simple.

In the class assassinscreed, add the following declaration:

 public static final PrintStream out = System.out;

Implementing the equivalent of the System.setOut() method is tricky. You could use reflection to update the value of the out “constant”. However, there’s a risk that some code will see stale copies of the reference. And I don’t think the JLS provides a way to mitigate that … because from the JLS perspective the value is not supposed to change.

So if you need to change the value of out on the fly, this is not the right solution. In fact, I’d say that it is not the right solution at all. It would be better to write this as:

private static PrintStream out = System.out;
public static PrintStream getOut() {
    returns out;
}

… with a setter if you need one.

(In my opinion, the classic design was a big mistake. It certainly made it a lot harder to implement light-weight applications within a JVM.)
