I have written a table of results for 2 booleans after applying logical opperators, but I need to the results to display 1, 0 in instead of true, false using casting.

code is as follows:

class LogicalOpTable{
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));

}
}

Any ideas?

i'd hope to know by then

what did you just say?

i didn't get any of that :[

Okay, coders feel free to slate me.. But something like this? (It's 2:30am)

If (p = true)
{
System.out.print("1");
}
else
{
System.out.print("0");
}

Totally not done programming in fucking ages, so that's more than likely totally fubar. But you get the idea.. Or use a switch and add in the conditions?

If this

boolean b = true;
int i = (int) p;

doesn't work and it does not, because boolean and int are inconvertible types, then a short solution is

boolean b = true;
int i = b ? 1 : 0;

but it isn't casting, it's working with a conditional operator.

i = b ? 1 : 0;

is the same as

if (b)
  i = 1;
else
  i = 0;

I don't know if this exercise was a kind of a homework or so, maybe it's a trick to say you got to do it with casting.

Yeah, you cant cast boolean to integers :>

You'll need to make a method something like this:

private int booleanConverter(boolean b) {
 if b = true
 return 1
 else
 return 0
 else return null //just a precaution, you never know :)
}

Then use this method in your System.out lines like this:

System.out.println(booleanConverter((p^q)) + "\t" + booleanConverter((!p)));

Im not 100% sure bout my syntax, havent coded for a long while, but i think you get my idea

edit: but i dont get why you cant use the true/false output

Its just System.out anyways

Crispy's way will work! Just remember the brackers round the if statements and the semicolons =)
