IllegalTriangleException Exercise 11.1 defined the Triangle class with three sides. in a triangle,the sum of any two sides is greater the the other side. the Triangle rule 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 as follows public class Triangle (double side1, double side2, double side3 ) throws IllegalTriangleException { // implement it}

public class Exercise12_05 {

public static void main(String[] args) {

    try {

      TriangleWithException t1 = new TriangleWithException(1.5, 2, 3);

      System.out.println("Perimeter for t1: " + t1.getPerimeter());

      System.out.println("Area for t1: " + t1.getArea());

   

      TriangleWithException t2 = new TriangleWithException(1, 2, 3);

      System.out.println("Perimeter for t2: " + t2.getPerimeter());

      System.out.println("Area for t2: " + t2.getArea());

    }

    catch (IllegalTriangleException ex) {
