Write a class called YourFirstNameLine that represents a line segment between two Points. Your Line objects should have the following methods: public YourFirstNameLine (Point pl, Point P2): construct a new Line that contains the given two Points public Point getStartPoint(): return this Line's first endpoint public Point getEndPoint(): return this Line's second endpoint public String toString(): return a String representation of this Line, such as “[(2,3), (4,7)]” public double getSlope(): return the slope of this Line. The slope of a line between points (x1, y1) and (x2, y2) is equal to (y2-yl)/(x2-x1). If x2 equals x1, the denominator is zero and the slope is undefined, so you may return a zero in this case public void draw (Graphics g): draw a line in a DrawingPanel. Write a client class called YourFirstNameLineTest with main method to test your Line class. In the main method, you need create a line object with the last four numbers of your Panther ID. For example, if your pantherid ends with xxxxx1234, then create and draw a line of between point (1,2) and point (3,4). (Hint: you will need the Point.java, DrawingPanel.java, YourFirstNameLine.java and YourFirstNameLineTest.java)

You will create a class called Square. Length will represent the length of one side which is an integer.You should create the constructor, an instance variable, a getter method for the length of a side, a getArea method and a toString method. The area of a square = length * length.Your toString method should be written such that it would return a String of the form "Square with side length: 8” (if the side length was 8) public class Square { //create one instance variable called length //create the constructor with one parameter //create your getter method to get the length of one side with return type integer //create the getArea method with return type integer //create the toString method }
