Chapter 5, Problem 2PE

Program Plan Intro

Ascending and descending order

Program plan:

• Import necessary package.
• Create a class “AscendingAndDescending”,
  • Define the method “main ()”,
    • Declare the necessary variables.
    • Create “Scanner” object.
    • Prompt the user to enter three integers.
    • Get three integers from the user using “nextInt()”.
    • Check whether the first integer is less than or equal to the remaining integers,
      • If it is true, assign the first integer to “low1”.
      • Check whether the second integer is less than or equal to the third integer,
        • If it is true, assign the second integer to medium.
        • Assign the third integer to “high1”.
      • Otherwise,
        • Assign the third integer to “medium”.
        • Assign the second integer to “high1”.
    • Otherwise,
      • Check whether the second integer is less than or equal to the remaining integers,
        • If it is true, assign the second integer to “low1”.
        • Check whether the first integer is less than or equal to third integer,
        • • If it is true, assign the first integer to “medium”.
          • Assign the third integer to “high1”.
            • Otherwise,
              • Assign the third integer to “medium”.
              • Assign the first integer to “high1”.
      • Otherwise,
        • Assign the third integer to “low1”.
        • Check whether the first integer is less than or equal to second integer,
        • • If it is true, assign the first integer to “medium”.
          • Assign the second integer to “high1”.
            • Otherwise,
              • Assign the second integer to “medium”.
              • Assign the first integer to “high1”.
    • Print the integers in ascending order.
    • Print the integers in descending order.
