Chapter 9, Problem 22PE

Program Plan Intro

To produce an array of first “n” values

Program plan:

• In a file “Sequence.java”,
  • Create a package.
  • Create an interface “Sequence”,
    • Declare a method “next()”.
    • Define a method “values()”,
      • Declare an array.
      • Create loop to iterate over array elements,
        • Assign the values for the array.
      • Return the array.
• In a file “SquareSequence.java”, create a package and then a class “SquareSequence”,
  • Declare the variable.
  • Define the method “next()”,
    • Increment the value by “1”.
      • Return the multiplied value.
• In a file “SequenceValuesTest.java”, create a package and then a class “SequenceValuesTest”,
  • Define the method “main()”,
    • Create object for “SquareSequence”.
    • Assign to the array, the values returned from the method “values()”.
    • Print the array.
    • Print the expected sequence of values.
