Thread: Do while loop in CeaserCipher

Hello friends long time no see! I've got a really simple question this time around and I'm not sure if im just oblivous or what. The question is in regards to this do whie loop.

 
public class test {
	public static void main(String[] args) {
		char input, encrypted;
		int distance;
 
		input = In.readChar();
 
		do {
			Out.println("input number between -10 and 10 without 0");
			distance = In.readInt();
		}while(distance < -10 || distance > 10 || distance == 0);
 
 
	encrypted = (char) ((input + distance % 128));
 
	Out.println(encrypted);
	}
}

Now If you look the text of the print statement and the while statement it (in my eyes) doesn't seem right. I'll try to explain what I see:

read in the values while the value is less than -10 or higher than ten or equal to null. Now the program works I've tested it but I obvioulsy dont have a good grasp of the do while loop (even tho I've used it before), so some explanation would be great.Thanks!

Yea I mean 0, my bad, I know its valid but it confuses me,as to how can we put distance > 10 because the values need to be within - 10 and 10, but this says greater than 10 or am i just that oblivious?

Okay, is there a way you could write comments in my code explaining step by step what the loop those? That would probably clear it up for me.

Omg now I see, thank Im just not on my game,I'm missing the easiest thing just not my day.Thanks buddy!

PS. I passed my programing curriculum with an B.
