Triangle Identifier

Write a program TriangleIdentifier.java that has the user enter the lengths of three sides of a triangle, s1, s2, and s3. The program should then identify the type of triangle it is and print out the String “equilateral”, “isosceles”, or “scalene”, as appropriate.

Variation

Write a method getType() that takes the sides of the triangle as inputs and returns a String value indicating the type of the triangle. Call this method from the main() program.

Extension

Ensure that the three sides can make a triangle. If the user enters 2, 3, and 7, for example, those side lengths can’t form a triangle. If the three sides can’t form a triangle, the program should print out the String “ERROR”.
