Ed.

I'm going to look it up, for once. Here's what the docs say, I think:

Integer.toBinaryString(n);

or

Integer.toString(n, 2);

Bear in mind that I know jack diddly squat about Java. 

dhromed:

 System.out.println(n.ToString());

Main.java:10: int cannot be dereferenced
System.out.println(n.ToString());

I ninja'd my post. See above.

If you take the literal code as you posted it, it's System.out.println("00000000000000000000000000000010");but I'm assuming it's not as useless as that, and that n is the input that comes form somewhere and that this code is supposed to convert to the binary string equivalent, for some infathomable reason.

 Use ABCL (then you'll get Java bytecode), and just do

(let ((n 2))
  (format T "~B" n))
10 

Oh, you wanted string padding? Sure, how about some mayo with it?

(let ((n 212))
  (format T "~17,'xB" n))
xxxxxxxxx11010100

Wow! Will download this and try thing out sometime. Thx.

or consider java.util.Formatter ... printf-like formatting capabilities ... its been around since Java 1.5

It should be able to zero-pad your output.
