# I have a Java assignment to finish. I have not recieved my

### Resolved Question:

I have a Java assignment to finish. I have not recieved my text just yet and it's extrememly difficult to complete without the text. I am at the job at the moment and can't use wikisend to attach the lab. If possible I would like to have it by noon sunday. Here it is below:
//week 1 - lecture: Triangle class

public class Triangle extends Point
{
private Point v1;
private Point v2;

public Triangle()
{
super(0, 0);
v1 = new Point(0, 1);
v2 = new Point(1, 0);
}

public Triangle(Point p1, Point p2, Point p3)
{
super(p1.getX(), p1.getY());
v1 = p2;
v2 = p3;
}

public void getVertices(Point p1, Point p2, Point p3)
{
p1.setX(getX());
p1.setY(getY());

p2.setX(v1.getX());
p2.setY(v1.getY());

p3.setX(v2.getX());
p3.setY(v2.getY());
}

public void setVertices(Point p1, Point p2 , Point p3)
{
setX(p1.getX());
setY(p1.getY());
v1 = p2;
v2 = p3;
}

public String toString()
{
return " Vertex 1: " + super.toString() + "\n" +
" Vertex 2: " + v1.toString() + "\n" +
" Vertex 3: " + v2.toString();
}

public double area()
{
return 0;
}
}

Exercise 2: User-defined methods

The function area of the Triangle class is the framework of the actual method. Modify it so that it calculates the area of the triangle. Write a Main class to test your area method. Note: to calculate the area of a triangle from the vertices, first find the distances between each pair of vertices to obtain the length of the sides of the triangle. Then apply Heron’s formula to calculate the area given the length of the sides.
Exercise 3: Shallow versus deep copy

Provide an example of shallow copy of objects and an example of deep copy of objects.
Exercise 4: Passing parameters to methods

Write a function that swaps two Point objects. Use the code given below:
import java.util.*;
public class Main
{
public Main()
{
Scanner in = new Scanner(System.in);
System.out. print("Enter x and y coordinates of first point: ");
Point p1 = new Point (in.nextDouble(), in.nextDouble());
System.out. print("Enter x and y coordinates of second point: ");
Point p2 = new Point (in.nextDouble(), in.nextDouble());
swap(p1, p2);
System.out.println("p1 = " + p1);
System.out.println("p2 = " + p2);
}
public void swap(Point p, Point q)
{
}
public static void main(String[] args)
{
Main myApp = new Main();
}
}
