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

class Line

{

protected Point P1;

protected Point P2;

public Line(Point p1, Point p2)

{

this.P1 = new Point(p1);

this.P2 = new Point(p2);

}

public Point getP1() { return(P1); }

public Point getP2() { return(P2); }

public String toString()

{

return(

new String(

"[(" + P1.getX() + "," P1.getY() + ") , (" + P2.getX() + "," + P2.getY() + ")]"

)

);

}

}

you than then call it as:

public static void main(String args[])

{

Point p1 = new Point (22,3);

Point p2 = new Point(4,7);

Line line = new Line(p1,p2);

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

}
