Program Plan Intro

Modified Diamond-Printing Program

Program Plan:

Filename: “Diamond.java”

• Import the header file.
• Define the “Diamond” class
  • Define the “drawDiamond” method
    • Create an object for “Scanner” class
    • Declare the required variables
    • The “do-while” loop is used to get the number of rows from the user.
    • Iterate “row” value from 1 to “numRows/2” for displaying top triangle
      • Iterate “spaces” value from “numRows/2” to “row” value
        • Display empty space
      • Iterate “stars” value 1 to “(2 * row) - 1” value
        • Display the “*” symbol.
      • Display the newline.
    • Iterate “row” value until it reaches the value greater than or equal to 1 for displaying bottom triangle
      • Iterate “spaces” value from “numRows/2” to “row” value
        • Display empty space
      • Iterate “stars” value 1 to “(2 * row) - 1” value
        • Display the “*” symbol.
      • Display the newline.

Filename: “Test.java”

• Define the “Test” class
  • Define the “main” method
    • Create an object for “Diamond” class
    • Call the “drawDiamond” method
