1. When the user enters a number for the side of a triangle, if the number is less than 1, the program must say "Error: numbers must be greater than or equal to 1" and then the program asks the user to enter the number for that side again

2. After the program receives 3 positive numbers and determines if it is a triangle or not, the program then asks "Enter 0 to end or 1 to repeat". If the user enters 0, the program ends. If the user enters 1, the program repeats and asks the user for 3 new sides of a potential triangle. You do not have to check if the user enters anything other than 0 or 1

Write a Java program that asks the user for 3 non negative integers that represent the lengths 3 sides of a triangle. After the user enters the numbers, the program determines if the 3 numbers make a valid triangle. If the 3 sides can make a triangle, the program prints "These numbers make a triangle". Otherwise, it prints "These numbers do not make a triangle"
