    Question Homework Help

    /***** DO NOT TOUCH ANYTHING HERE ***********/
    import java.io.*;

    public class Homework4{

    public static void main (String args []) throws IOException{

    //how many stars you want
    int stars = 0;
    System.out.println("Please enter the max number of * you want to see on your triangle");

    // Hook up br to standard input.
    BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
    stars = Integer.parseInt(br.readLine());

    for (int i = 0; i < stars; i ++){
    /*******ENTER MAIN PROGRAM STARTS HERE *****************/
    System.out.println("*");
    System.out.println("\n");
    }
    }
    }
    }

    this is the program and we are suppose to add one more * each time the loop executes. The instructor said to not use char and that it requires a loop.:confused:
    I just need some tips on where to place the loop.

    You're going to have to provide more information than what you have. We don't know what your assignment is. The best I can guess is that he wants a triangle to be printed out with a bunch of stars... but that's still not really very helpful.

    Also, when you post a question, use [code] tags and post some things you've tried already--this isn't a freebie forum, it's a help forum.

    If you're looking for where to put the loop, it looks like it's already in there. The line above "/*******ENTER MAIN PROGRAM STARTS HERE *****************/" is a for statement, which starts a loop for those 3 conditions. The for Statement (The Java™ Tutorials > Learning the Java Language > Language Basics)

    The program as it is will in no way print a triangle of stars, your for loop needs addtional code to make that happen, what kind of triangle should it be?
