java without using prime method

1. Write an application that inputs a 3-digits number from the user and checks if all digits are prime numbers. If all digits are prime your program should stop. Use do/while for reading the input and any loop format to test if the number is prime. When checking the prime numbers dont use an if to check numbers from 1 9; you need to find an algorithm to check if the number is prime or not.

	Enter a 3-digit number: 124 4 is not a prime number! Enter a 3-digit number: 642 6 is not a prime number! 4 is not a prime number! Enter a 3-digit number: 352 All Prime! Thank You!
