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 2.19.

Which of the following are correct literals for floating-point numbers? 12.3, 12.3e+2, 23.4e-2, -334.4, 20.5, 39F, 40D
