Write this program in Java please

Write a program that reads three edges for a triangle and computes the perimeter if the input is valid. Otherwise, display that the input is invalid. The input is valid if the sum of every pair of two edges is greater than the remaining edge. Example: If you entered the three edges to be 3, 4, 5, then your program should show the sum of any two edge is greater than the remaining edge, 3 + 4 > 5, 3 + 5 > 4, 4 + 5 > 3 thus this is a valid triangle and the perimeter is 12
