Challenge to new programmers!

[Xeox]

Make a program that prints out the binary representation of an integer. Does not have to deal with negatives. I will post my way of solving this in a week, maybe sooner. Oh and no it's not a homework assignment of mine!

I think the point of this is to write your own algorithm that converts an integer to binary

Yea, it was a practice question for my first College CS exam, and I just thought it would liven things up a bit in the Java forum.

I will try this one day that I have some experience. I'm starting programming this week, but nto sure what language to start on.

didn't realize you could directly convert integers to hex, octal and binary so easily

public void intbin(int input)
{
    int i;
    for(i = 0; i < 32; i++)
    {
        System.out.print(( input >> 31)&1);
        input <<= 1;
    }
    System.out.print("\n");
}

whadu i win

import javax.swing.*;
public class DecToBin{
public static void main(String [] args){
int numDec=0
String numBin="";
numDec=Integer.parseInt(JOptionPane.showInputDialog("Enter a number:"));
while(numDec>=1)
{
if(numDec==1){
numBin="1"+numBin; break;
}
else{
if(numDec%2==0)
{ numBin="0"+numBin;numDec/=2;}
else
{ numBin="1"+numBin;numDec/=2;}
}
}
JOptionPane.showMessageDialog(null,"Binary Number:"+numBin);
System.exit(0);
}
}
//i hope that this will work ^_^

There are two binary representations, a mathematical and a computational.

where 000... is -2,147,000,000 or something in computational
and on a mathematical base 32 zeros would be 2^32.
Which one are you referring to?
