        • 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.
