Thread: Bigger triangle made up of multiple ones?

Hey everyone! I have an assigment due next Monday, and in this assignment I must create an ASCII triangle in Java. I've managed to do that, but for extra credit I have to do something like this:



Here is the code I have so far:

/**********************************************************************
* Program: Triangles                                                  
* Author:                                                             
*                                                                     
* Programming Assignment #2                                           
* Date:                                                               
*                                                                     
* This program prompts the user to input the length of the side of an 
* equilateral triangle that is larger than 2. An equilateral triangle 
* will then be created using the ASCII character "*" (ASCII graphics) 
*                                                                     
* Input:                                                              
* Side of the equilateral triangle                                    
*                                                                     
* Output:                                                             
* An equilateral triangle made in ASCII graphics

        }
 
        //Loop that controls how many stars are in each line

        {
      	  System.out.print("* ");
        }
 
        System.out.println();	 
      }
    }
 
    Start=false;
    option = console.readLine("Would you like to make another triangle? Please type either 'Yes' or 'No': ");
 
    if (option.equals("Yes"))
    {
      Start=true;
    }	
 
    else if (option.equals("No"))
    {
      System.out.println("Goodbye!");
      System.exit(0);
    }
   }
 
   /*Finds if an inappropriate response (Ex: Typing in 1 when prompted for a yes or no answer) is given
    *and closes the program if one isn't*/
   catch(Throwable e)
   {
     System.out.println("Please type in an appropriate response next time. Goodbye!");
     System.exit(0);	
   }		     	
  } 
 }
}

Apparently I have to make a larger triangle out of the smaller ones, but I'm not quite sure how to approach it. Any help would be greatly appreciated!

I would draw a bigger triangle out of smaller ones.
