Sort the string

Program plan:

Filename: “Main.java”

• Include the required header files.
• Define the “Main” class
• Define the main method.
  • Declare an object for “Scanner” class.
  • Get the month and day from the user.

  • Call the methods and display the sorted order of strings.

Filename: “StringSet.java”

• Define the “StringSet” class.
  • Declare the required variables.
  • Define the constructor
    • Set the values.
    • If the string 2 is less than 0, then set string 2 as a smallest.
    • If the string 3 is less than 0, then set string 3 as a smallest.
    • If the string 2 is greater than 0, then set string 2 as a largest.
    • If the string 3 is greater than 0, then set string 3 as a largest.
    • Check string 1 is not equal to smallest and largest values.
      • Assign string 1 to the “middle” variable.
    • Check string 2 is not equal to smallest and largest values.
      • Assign string 2 to the “middle” variable.
    • Otherwise, assign string 3 to the “middle” variable,
  • Define the “getSmallest()” method.
    • Return the smallest value.
  • Define the “getLargest ()” method.
    • Return the largest value.
  • Define the “getMiddle ()” method.
    • Return the middle value.
