    Default Program without loops and recursion

    Hi,
    I was asked to write a Java pgm in a contest. But i couldn't do it. I don't know the answer yet. So, I thought i'd ask here. And the problem is , can we write a java program to print numbers 1 to 1000 without using any loops and recursion?

    You can use library functions as well.

    Please any one say, if it is possible.

    Well you could hard code the numbers in xD

    There are many solutions which claim to satisfy this, but it depends on what you take to be recursion and loops, does this include compile time loops and recursion?

    Hard coding is the easiest method.

    A swing timer/event driven model might count depending on who you ask (there are parts that could be considered recursive or loops)

    The program should not syntactically contain any loops or recursion. that's it.
    Btw, i don't want to hard code.
    Pls give me any 1 soln...

    We won't just give you a solution. If you want an event-driven program, I'd suggest reading on Swing Timers and Action Listeners.

    Ok. Thanks for your ideas. I managed to do it with Timers.

    Sort of a silly contest problem... hard coding is the obvious method, and you could write a trivial ~20 line program to generate the >1000 line program in literally no time.
    Let me know what you think of my website:

    Comments or suggestions are appreciated!

    True, you can also use divide & conquer approach

    It's a well known programming challenge, it's more to stimulate the mind and get you thinking about ways of doing things.
