Program Plan Intro

Electromagnetic spectrum

Program plan:

• Create a class “Wavelength”,
  • In the body of “main()” method, create the object for “Scanner” class to get the input from the user.
  • Get the type of input from the user using “next()” method.
  • Compare whether the type of input is “wavelength” using “compareTo()” method.
  • If the input is “wavelength” then,
    • Declare and initialize the required variable for different wavelength.
    • Call the method “nextDouble()” to get the value from the user.
    • Compare the entered value with the initialized wavelength using “nested- if… else” statement.
    • Display the particular part of electromagnetic spectrum corresponding to a wavelength.
  • Else,
    • Declare and initialize the required variable for different frequency.
    • Call the method “nextDouble()” to get the value from the user.
    • Compare the entered value with the initialized frequency using “nested- if… else” statement.
    • Display the particular part of electromagnetic spectrum corresponding to a frequency.
