Write a Java program that has a single module with twoclasses:1. A public class that contains the main method, and does thefollowing:
Creates a Triangle object, triangle1, using the defaultconstructorCreates a Triangle object, triangle2, using these values: 3, 4,5
Gets the perimeter and area of triangle1 using thecorrespondingmethods and prints them out with 3 decimals.
Gets the perimeter and area of triangle2 using thecorrespondingmethods and prints them out with 3 decimals.
2. A class named Triangle, which contains:
Three integer data fields named side1, side2 and side3– thesides of the triangle
A no-arg constructor that creates a default triangle where allsides are of length 1.
A constructor that takes 3 integers, each corresponding to aside in the triangle.
Setter and Getter methods for the length of each side of thetriangle
A method named getPerimeter() that returns the perimeter of thetriangle as an integer.
A method named getArea() that returns the area of the triangleas a double. Your program must use the methodology shown onthis website for getting the area of a triangle from 3 sidelengths: Area of Triangle with 3sides. https://www.cuemath.com/measurement/are ... s/Programs with syntax errors will not beaccepted.
