I need help with a Java assignment: This problem requires three separate classes

Question

I need help with a Java assignment:

This problem requires three separate classes, each in its own file.

class TeenInteger

has one type int data member intended to hold an integer from 13-19 inclusive.

has a constructor that can assign the integer's value, but only if it is in the range 13-19. If the value is out of range, a custom exception named BadTeenInputException should be thrown.

has a getter that returns the int data member. There is no setter.

class BadTeenInputException

extends class Exception, as all custom exceptions must do.

has one int data member for a "teen integer".

has a constructor like the one coded in Listing 12.10 on page 474.

has a getter for the int data member.

class TestTeenInteger

has a main method and a method named teenInfo that takes a TeenInteger argument.

In main

prompt the user to enter a "teen integer" int value.

in a try block, attempt to create a TeenInteger object with this int value and call teenInfo with this TeenInteger object as argument.

follow the try block with a catch block that catches a BadTeenInputException and displays an error message.

In teenInfo

print the valid "teen integer" and report it as either even or odd.

Sample Run 1

Enter a 'teen' integer (13-19) 14

14 is an even number

Sample Run 2

Enter a 'teen' integer (13-19) 17

17 is an odd number

Sample Run 3

Enter a 'teen' integer (13-19) 22

22 is an invalid teen integer. Must be 13-19, inclusive

Explanation / Answer

public class TeenInteger { private int number; public TeenInteger(int num) throws BadTeenInputException { if(num < 13 || num > 19) { throw new BadTeenInputException(num); } this.number = num; } public int getNumber() { return number; } } public class BadTeenInputException extends Exception { private int teenInteger; public BadTeenInputException(int teenInteger) { this.teenInteger = teenInteger; } public int getTeenInteger() { return teenInteger; } } import java.util.Scanner; public class TestTeenInteger { public static void teenInfo(TeenInteger integer) { if(integer.getNumber() % 2 == 0) { System.out.println(integer.getNumber() + " is an even number"); } else { System.out.println(integer.getNumber() + " is an odd number"); } } public static void main(String[] args) { Scanner in = new Scanner(System.in); System.out.print("Enter a 'teen' integer (13-19) "); int num = in.nextInt(); try { TeenInteger teenInteger = new TeenInteger(num); teenInfo(teenInteger); } catch (BadTeenInputException e) { System.out.println(e.getTeenInteger() + " is an invalid teen integer. Must be 13-19, inclusive"); } } }
