java programming

Modified the Triangle class you created for lab \#2. In a triangle, the sum of any two sides is greater than the other side. 1. Define the IllegalTriangleException class that extends the Exception class. This class contains only two constructors: a no-arg constructor and a constructor which takes a string parameter. 2. Modify the second constructor of the Triangle class (The constructor creates a triangle with the specified side1, side2, and side3). In this constructor, if the three sides violate the rule| specified above, throw an IllegalTriangleException exception. Write a test program that does the following tasks: 1. Create a text file called sides.txt which contains three randomly generated integers between 1 and 10. 2. Input the three integers from the sides.txt file. 3. Write a try block. In the block, create a new Triangle object using the three integers. 4. Write a catch block to handle the IllegalTriangleException. In the block, print the message: "IllegaiTriangleException: The triangle cannot be created." private string color = "whit private boolean filled; private java.util.
