Thread: Building a triangle using strings and loops...program trouble.

Hi all, I have a project that I've been trying to do where you need to create a triangle using String objects as well as loops.

The end result has to look like this: (the triangle needs to be complete at the bottom line but I can't get it to turn out right on this message board)

     *
    * *
   *   *
  *     *

We are given the example using this code:

public class Triangle {
 
    public static void main(String[] args) {
 
        int length = 16;
 
        String border = new String(""); //declaring string object named border
 
        for(int n = 1; n <= length; n++)
        {
            border+='*';
        }
 
       //***************************************
 
        String spaces = new String("");
 
        for(int n = 1; n <= border.length()-2; n++)
        {
            spaces+=' ';
        }
 
        //****************************************
 
        int slength = 2;
 
        String sides = new String("");
 
        for(int n = 1; n <= slength; n++)
        {
            sides+='*' + spaces + "*\n";
        }
 
 
    String box = border + '\n' + sides + border + '\n';
 
    System.out.println(box);
 
    }
}

I have no clue how get each row to descend by one space. It's really confusing me logically especially since for loops are involved.

This is what I have so far... even though it's not much.

public class Triangle2 {
 
 
    public static void main(String[] args) {
 
 
       int length = 1;
 
       String tip = new String("");
 
       for(int n=1; n<=1; n++)
       {
           tip+='*';
       }
       //******************************************
 
       System.out.println(tip);
 
 
       String spaces = new String("");
 
       for(int n=1; n<=1; n++)
       {
 
       }
 
 
    }
}

Any help would be appreciated!

You are most likely going to want to use nested for loops rather than separate loops.
