public class TestIntw
{
public static void main (String [] args)
{
System.out.println("Hello");
}
}

In the above code, without changing the main , how can we print "Hello world" instead of "Hello". And also "Hello" should not be printed. Only "Helloworld" should be printed.

Since java is open source now we can change the behavior of System.out.println(String s).

I highly doubt that this is a mock SCJP question, but okay....

How about adding a static initializer that displays "Hello World", and calls exit(), so that the main method doesn't run?

Use a debugger? Use AspectJ to write an aspect with a pointcut to catch the call to System.out.println()? Dunno, you going to tell us?

Hi Shaiber,

Here we go....

import java.io.*;
public class TestIntw
{
public static void main (String [] args)
{
System.out.println("Hello");
}
}

class System{

static final PrintStream out = new PrintStream(java.lang.System.out){
public void println(String s){
java.lang.System.out.println("Helloworld");

}
};
}

Lets Rock
