Thread: Using Nested Loops

Display the following: Using loops

    1
   21
  321
 4321
54321

This is my attempt.

public class UsingLoops {
    public static void main(String[] args) {
        for (int line = 1; line <= 5; line++) {
            for (int j = 1; j <= (-1 * line + 5); j++) {
                System.out.print(" ");
            }
            System.out.print(line);
            for (int j = 1; j >= (-1 * line + 3); j--) {
                System.out.print(j + 3);
            }
            System.out.println();
        }
    }
}

This is the output that I get:

    1
   24
  343
 4432
54321

What am I doing wrong? How do I fix my code?
It appears the space aren't showing when I created this thread. There is supposed to be 4 spaces before the first line, 3 spaces before the second line and so on.

this is my answer....
try this....

I understand your point about spoon feeding, but the guy is asking for help, don't u think he can sit and think if he had to ? and if he knew that he needs help, then he would ask for it ? I don't understand why the strict rules about not posting solutions...you always learn ...even if u took someone else's code and studied it, you would still learn, I'm sure that you can write more than one piece of code to do the exact same thing. so why not post a solution, and let the person asking for help, get the idea, and then try to recode it. Or perhaps if you really want, maybe u can use by pesudo code, instead of complete code, which in a way makes them learn the syntax better.

Did you read the link provided above? It contains much of the reasoning behind spoon feeding, which is supported by the moderating team here as well as every other forum you might visit. So I will leave it up to you to read and digest its points. Should you like to continue to discuss, then please make another thread, use the private messaging feature, or start a conversation rather than continuing in this thread
