Program Plan Intro

Implementation of “PrimeSequence” class

Program plan:

  • In a file “Sequence .java”,
    • Create a package.
    • Create an interface “Sequence”,
      • Declare the method “next()”.
  • In a file “PrimeSequence .java”,
    • Create a package.
    • Create a class “PrimeSequence”,
      • Initialize the variable to “2”.
      • Use naïve algorithm to produce the next value in the sequence of prime using the following “next()” method.
      • Define the method “next()”,
        • Initialize the Boolean variable to false.
        • Execute he following,
          • Declare the loop variable.
          • Create loop to check each number less than the “n” for divisibility of “n”.
          • Check whether the value is same as “n”,
            • If it is true, set the Boolean variable to true.
          • Increment the counter variable.
        • End the loop while the condition is false.
        • Return the value.
  • In a file “SequenceDemo.java”,
    • Create a package.
    • Create a class “SequenceDemo”,
      • Define the method “main()”
        • Create object for “PrimeSequence”.
        • Execute lop for “100” times,
          • Print the prime number obtained by “next()”.
