Upside Down Triangle


Create a method printUpsideDownTriangle(int width) that takes a width as an argument and prints an upside down triangle whose base is width wide.


class UpsideDownTrianglePrinter {
  public static void main(String[] args) {
    System.out.println(); //print a blank line.

When executed, the above program would print:




Submit the .java file that contains your printUpsideDownTriangle(int width) method. You may also include a main() method but this will not be graded.


  • Think of the triangle as a table with rows and columns. How many *s are printed at each row?
  • Use a flowchart to design your algorithm first. You may even use visual logic if you please and then translate it to a Java program.
  • Notice what is to the left of the asterisks. ' ' or " " may be used as spaces.

Extra Credit

  • (2 points) Accept an additional parameter that dictates the character to use to draw the triangle, e.g., upsideDownTriangle(int width, char character). Use this character to draw the triangle.
