Part 1 - Assignment

NOTE: The use of recursive method calls is not allowed.

Create a class named, ArrayProcessing

• The class should have the following fields:

  • One array that will hold 5 objects of type int. You pick the name.
  • One Scanner object. You pick the name.

• The class should have a constructor that performs the following:

  • Creates the array and Scanner objects (they are already declared as fields, now they need to be “created”).
  • Calls the method getNumbers.
  • Calls the method processNumbers.

• Create a method named, getNumbers, with a return type of void and no parameters that does the following:

  • Uses a for loop to prompt and grab five integers from the terminal window using the Scanner object and assign each one to an array element.
    • NOTE: Do not use the constant 5 in the for-loop test, use the length field.

• Create a method named, processNumbers, with a return type of void and no parameters that does the following:

  • Uses an appropriate loop statement to:
  • Call the method printMenu.
  • Test the result returned from printMenu and calls one of the processing methods: add, mult, print, reverse.
  • If the result returned from printMenu is invalid, an error message is printed.
  • Uses a call to the method named, again, as the loop condition which allows the whole process above to repeat until the result from the again method is false.

• Create a method named, printMenu, with a return type of int and no parameters that does the following:

  • Prints the following menu to the terminal window:

  Choose an option to perform:
  1) Add numbers
  2) Multiply numbers
  3) Print numbers
  4) Print number in reverse
  

  • Grabs input from the Scanner object and returns it to the calling statement.

• Create a method named, add, with a return type of void and no parameters that does the following:

  • Uses a for loop and the array length field to sum the numbers in the array and print the final sum, with the appropriate label, only once to the terminal window.
    • NOTE: Do not use the constant 5 in the for-loop test, use the length field.

• Create a method named, mult, with a return type of void and no parameters that does the following:

  • Uses a for loop and the array length field to multiply the numbers in the array together and print the final product, with the appropriate label, only once to the terminal window.
    • NOTE: Do not use the constant 5 in the for-loop test, use the length field.

• Create a method named, print, with a return type of void and no parameters that does the following:

  • Uses a for loop and the array length field to print each number, with the appropriate label, in the array to the terminal window.
    • NOTE: Do not use the constant 5 in the for-loop test, use the length field.

• Create a method named, reverse, with a return type of void and no parameters that does the following:

  • Uses a for loop and the array length field to print each number in the array IN REVERSE ORDER, with the appropriate label, to the terminal window.
    • NOTE: Do not use a constant in the for-loop, use the length field.

• Create a method named, again, with a return type of boolean and no parameters that does the following:

  • Prompts the user to enter the integer 1 to choose another option or 2 to exit.
  • Grabs an int from the terminal using the Scanner object.
  • Tests the number entered and returns true if the int is a 1 and false if it is something else.
