Create a custom Exception named IllegalTriangleSideException. Create a class named Triangle. The Triangle class should contain 3 double variables containing the length of each of the triangles three sides. Create a constructor with three parameters to initialize the three sides of the triangle. Add an additional method named checkSides with method header - *boolean checkSides() throws IllegalTriangleSideException *. Write code so that checkSides makes sure that the three sides of the triangle meet the proper criteria for a triangle. It will return true if and only if the sum of side1+ side2 is greater than side3 AND the sum side2+side3 is greater than side1 AND the sum of side1+ side3 is greater than side2. If any of those three conditions is not met, the method will create and throw an IllegalTriangleSideException. Add a main method to create and check two to three different triangles.

class IllegalTriangleSideException extends RuntimeException{
   public IllegalTriangleSideException(String m) {
       super(m);
   }
}
public class Triangle {
   private double side1;
   private double side2;
   private double side3;
   public Triangle(double aSide1, double aSide2, double aSide3) {
       super();
       side1 = aSide1;
       side2 = aSide2;
       side3 = aSide3;
   }
   boolean checkSides() throws IllegalTriangleSideException{
       if ((side1 + side2) > side3)
               throw new IllegalTriangleSideException("Invalid Sides");
       else
           return true;
   }
}
