This one seems alright to look at but gives me an
ArrayIndexOutOfBoundsException. I can't see where I am crossing the
array bounds.

//package sathyaish.practice.utilities;

/*
I want to see how many expressions I can append to a single for-loop
statement in Java.

        for ( int i = 0; i < args.length; i++, sb.append( args[i] ),
sb.append(delimiter));
*/
public class lfl /* long for loop */
{
    public static void main(String[] args)
    {
        if ( args.length == 0 )
            System.out.println("Usage lfl arg1 [arg2 [arg3...]]");

        java.lang.StringBuffer sb = new StringBuffer();
        for ( int i = 0; i < args.length; i++, sb.append( args[i] ),
sb.append(" "));
        System.out.println(sb.toString());
    }
}

Test:
