1.

a. Write a class called Triangle that implements the Comparable interface. The class should contain 3 fields: vertexA (Point), vertexB (Point), vertexC (point). Write the necessary constructors, accessors, mutators and other methods. The Point class is given below.

b. Write a client class that creates an ArrayList of 10 Triangle objects called list1.

Print the list.

Call Collections.sort(list1), to sort the elements according to the area of the triangle.

Print the sorted list.

public class Point {

private int x;

private int y;

public Point() {

this(0, 0);

}

public Point(int x, int y) {

this.x=x;

this.y=y;

}

public int getX() {

return x;

}

public int getY() {

return y;

}

public String toString() {

return "(" + x + ", " + y + ")";

}

}
