Specifications

• A prime number is divisible by two factors (1 and itself). For example, 7 is a prime number because it is only divisible by 1 and 7.
• If the user enters an integer that’s not between 1 and 5000, the application should display an error message.
• If the number is a prime number, the application should display an appropriate message.
• If the number is not a prime number, the application should display an appropriate message. Then, it should display the number of factors for the number and a list of those factors.
• Store the factors for each number in an ArrayList.
• Use the Console class presented in chapter 7 or an enhanced version of it to get and validate the user’s entries.
• After each number is entered and checked, the original value and the resulted line should be written to a file named primeNumber.txt. When the user exits the application primeNumber.txt should contain all the lines and translations that were created during that session.
