How to modify this program to use & display 1s and 0s instead of true and false?

class LogicalTable{
	public static void main(String[] args){
		boolean p, q;

		System.out.println("P\tQ\tAND\tOR\tXOR\tNOT");

		p=true; q=true;
		System.out.print(p+"\t"+q+"\t");
		System.out.print((p&q)+"\t"+(p|q)+"\t");
		System.out.println((p^q)+"\t"+(!p));
		


		p=true; q=false;
		System.out.print(p+"\t"+q+"\t");
		System.out.print((p&q)+"\t"+(p|q)+"\t");
		System.out.println((p^q)+"\t"+(!p));


		p=false; q=true;
		System.out.print(p+"\t"+q+"\t");
		System.out.print((p&q)+"\t"+(p|q)+"\t");
		System.out.println((p^q)+"\t"+(!p));


		p=false; q=false;
		System.out.print(p+"\t"+q+"\t");
		System.out.print((p&q)+"\t"+(p|q)+"\t");
		System.out.println((p^q)+"\t"+(!p));

	}
}

public int convert(boolean value) {
  return value ? 1 : 0;
}

Call this method to convert a boolean to an int in the way you described.

Hi and welcome to the JavaRanch.

I've edited your post and added code tags making it much easier to read. Please do so in the future.

We are NotACodeMill, what have you tried? What failed? And why?

Thank you guys!!

Paul Clapham, where should I put your code? and why?

Wouter Oet, I'll follow the rule in the future. Well, I'm trying to use and show 1s and 0s instead of true and false. I've replaced true to 1 and false to 0.
compiler says "incompatible types. found: int, required: boolean"

You need to use it where you want the output, so:

System.out.println(convert(...your statements here...));
