Program Plan Intro

Modified version of “Coin” class

Program plan:

• In a file “Coin.java”,
  • Create a package.
  • Class a class “Coin”,
    • Declare the necessary variables.
    • Define the constructor to assign initial values for the variables.
    • Define a method “getValue()” to return the coin value.
    • Define a method “getName()” to return the coin name.
    • Define a method “compareTo()”,
      • Assign the object properties to “Coin”
      • Check whether the coin value is less than the specified coin value.
        • If it is true, return “1”.
      • Otherwise, check whether the coin value is greater than the specified coin value,
        • If it is true, return “1”.
      • Otherwise, return “0”.
• In a file “CoinTest.java”,
  • Create a package.
  • Create a class “CoinTest”,
    • Define the method “main()”,
    • Create objects for “Coin” class with different properties.
    • Print the value returned from the method “compareTo()” when comparing first and second coin properties.
    • Print the expected value.
    • Print the value returned from the method “compareTo()” when comparing second and third coin properties.
    • Print the expected value.
    • Print the value returned from the method “compareTo()”, when comparing third and first coin properties.
    • Print the expected value.
