Question

Write a class called Line that represents a line segment between two Points. Your Line objects should have the following methods: public Line(Point p1, Point p2) Constructs a new line that contains the given two points. public Point getP1() Returns this line's first endpoint. public Point getP2() Returns this line's second endpoint. public String toString() Returns a string representation of this line, such as "[(22, 3), (4, 7)]"

Answer 1

Answer:

import java.awt.Point;

public class Line{

private Point point1, point2;

public Line(Point p1, Point p2){

point1 = p1;

point2 = p2;

}

public Point getP1(){

return point1;

}

public Point getP2(){

return point2;

}

public String toString(){

return "[( The " + point1.x + "," + point1.y + "), (" + point2.x + "," + point2.y +")]";

}

public static void main(String args[]){

Line lineObj = new Line(new Point(7,9), new Point(6,2));

System.out.println(lineObj.toString());

}

}

Explanation:

• Declare the points inside the class Line.
• Initialize the getters and setters method for the class.
• Define a toString method that returns the information in a formatted manner.
• Inside the main method, initialize an object with some values.
• Display the information by calling the toString method.
