I’ve pasted a question before on java programming.But never quite got the answer I was expecting.This time,I’m approaching the other way around.Instead of asking for a code,I would like somebody to guess what this code*below*is all about…:)Ten points to whoever gets it right,it’s education.And if anyone’s learn Java before,try it.I might be helping you remember your skills again.And please,be more specific.HERE WE GO!

public class Cards {

public static void main(String[] argv) {
Card a = randomCard(), b = randomCard();
int comp = a.compare(b);
if(comp == 0)
System.out.println(a.toString() + ” = ” + b.toString());
else if(comp < 0)
System.out.println(a.toString() + " < " + b.toString());
else
System.out.println(a.toString() + " > ” + b.toString());
}
