/*If you have three positive integers, you can determine whether or not those three values could represent the three sides of a triangle. If they do happen to represent a triangle, you can even determine what type of triangle it is (equilateral, isosceles, or scalene).
Write a program, called TriangleTypes.java, that will determine if the given lengths of three sides of a triangle (either given by the user or generated randomly) represent a valid triangle and if so what type of triangle it is.
If three given lengths are to represent a valid triangle, the sum of the lengths of any two sides must be greater than the third side.*/ import java.util.Scaer;
