In Java

In a triangle, the sum of any two sides is greater than the other side. The Triangle class must adhere to this rule. Create the IllegalTriangleException class, and modify the constructor of the Triangle class to throw an IllegalTriangleException object if a triangle is created with sides that violate the rule. The constructor of IllegalTriangleException must encapsulate all three sides of the triangle and a string message, as follow:

public IllegalTriangleException(double side1, double side2, double side3, String msg)

Write a test program to test your IllegalTriangleException by creating 2 instances of triangle with one of them violating the rule. Print the perimeter and area of the legal triangle. Print the sides and string message of the illegal triangle from the IllegalTriangleException caught.
