Create a class named MyTriangle that contains the following two methods:

/** Return true if the sum of any two sides is

  * greater than the third side. */

public static boolean isValid(   double side1, double side2, double side3)

/** Return the area of the triangle. */

public static double area(   double side1, double side2, double side3)

Write a test program that reads three sides for a triangle and computes the area if the input is valid. Otherwise, it displays that the input is invalid. The formula for computing the area of a triangle is given in Programming Exercise.
