Question

In Java.

Implement the classes shown in the following two pictures. Test your classes and methods (you do not need to test the getters and setters). MyPoint class is the same as the MyPoint class of Problem 3. 3 MyPoint -x:int vertices -y:int My Triangle -v1: MyPoint -v2: MyPoint -V3: MyPoint +My Triangle(x1:int, yl:int, x2:int,y2:int,x3:int, y3:int) +MyTriangle(v1: MyPoint, v2: MyPoint, v3: MyPoint) +toString():String +getPerimeter(): double +getType(): String "My Triangle[v1=(x1, y1),v2=(x2, y2), v3=(x3,73)]" "Equilateral" or "Isosceles" or "Scalene"

Answer 1

Thanks for the question. Below is the code you will be needing. Let me know if you have any doubts or if you need anything to change. 

Let me know for any help with any other questions.

Thank You!

public class MyTriangle {

    private MyPoint v1;
    private MyPoint v2;
    private MyPoint v3;


    public MyTriangle(int x1, int y1, int x2, int y2, int x3, int y3) {

        v1 = new MyPoint(x1, y1);
        v2 = new MyPoint(x2, y2);
        v3 = new MyPoint(x3, y3);
    }

    public MyTriangle(MyPoint v1, MyPoint v2, MyPoint v3) {
        this.v1 = v1;
        this.v2 = v2;
        this.v3 = v3;
    }

    @Override
    public String toString() {
        return "MyTriangle [" +
                "v1=" + v1 +
                ", v2=" + v2 +
                ", v3=" + v3 +
                ']';
    }

    public double getPerimeter() {

        return v1.distance(v2) + v2.distance(v3) + v3.distance(v1);
    }

    public String getType() {

        double v1v2 = v1.distance(v2);
        double v2v3 = v2.distance(v3);
        double v3v1 = v3.distance(v1);

        if (v1v2 == v2v3 && v2v3 == v3v1) return "Equilateral";
        else if (v1v2 == v2v3 || v1v2 == v3v1 || v2v3 == v3v1) return "Isosceles";
        else return "Scalene";
    }
