Thread: Simple coding question, 1 error

Im reading this book called "Head First Java" by Kathy Sierra and on page 20 it says this. This is the link to the page i am on and the problem i need to work.

http://books.google.com/books?id=uIV...uffle1&f=false


this is the code i wrote.

public class Practice {
public static void main(String[] args){
int x = 3;
while (x > 0) {
if (x > 2) {
System.out.print("a");
}
if (x == 2) {
System.out.print("b c");
}
if (x == 1) {
System.out.print("d");
x = x - 1;
}
x = x - 1;
System.out.print("-");
}
}
}

I am supposed to get the answer: a-b c-d
instead i get the answer: a-b c-d-

How is this?

It's

System.out.print("-");

Put some breakpoints out and follow whats happens and im sure youll get a clearer picture of what's happening.

--- Update ---

public class Practice {
 
	public static void main(String[] args) {
		int x = 3;
		while (x > 0) {
 
			if (x > 2) {
				System.out.print("a");
				System.out.print("-");
			}
 
			if (x == 2) {
				System.out.print("b c");
				System.out.print("-");
			}
 
			if (x == 1) {
				System.out.print("d");
				x = x - 1;
			}
 
			x = x - 1;
			//System.out.print("-");
		}
	}
}

What you're doing is printing out a "-" every time in the while loop. You loop 3 times therefore you'll get the "-" 3 times as well. But like a said follow the debuggers it's a good way to learn.
