A clаss which is extended by аnоther clаss is called a superclass.
In the text bоx belоw write а clаss nаmed Rectangle, which extends the fоllowing abstract BoundingBox class (15 points): /** * * Programmer: Benjamin Riveira */public abstract class BoundingBox { private int x, y; public BoundingBox() { x = 0; y = 0; } public BoundingBox(int newX, int newY) { setX(newX); setY(newY); } public void setX(int newX) { if(newX >= 0) { x = newX; } } public void setY(int newY) { if(newY >= 0) { y = newY; } } public int getX() { return x; } public int getY() { return y; } @Override public String toString() { return "(" + x + ", " + y + ")"; } public abstract double getArea(); } Your Rectangle class must extend the BoundingBox class above and must include all of the following variable declarations and method definitions: Two private int-type global variables named length and width. One no-argument constructor which constructs a Rectangle object with a default length of 1 and a default width of 1. One constructor with newLength and newWidth parameters which constructs a Rectangle object with the given newLength and newWidth values. One constructor with newX, newY, newLength and newWidth parameters which constructs a Rectangle object with the given newX, newY, newLength and newWidth values. A method named setLength, with a newLength parameter. This method should set the length global variable to newLength if and only if length is greater than zero. A method named setWidth, with a newWidth parameter. This method should set the width global variable to newWidth if and only if width is greater than zero. A method named getLength which returns the int-type value of the length global variable. A method named getWidth which returns the int-type value of the width global variable. A toString() method override which returns a String containing the x and y coordinates and the length and width of this Rectangle object. A getArea() method override which returns the area of this Rectangle object (length times width) as a double-type value. NOTE: PASTE ONLY THE SOURCE CODE FOR YOUR RECTANGLE CLASS INTO THE TEXT BOX BELOW. To receive full credit on this exercise your Rectangle class must compile when I copy and paste it into my NetBeans project which contains the BoundingBox abstract superclass shown above, and a test class which creates Rectangle objects. Additionally, my test program must compile and run with your Rectangle class in the project. This means that your Rectangle class must be complete and correct and must be free of errors which would show up as red underlines in NetBeans or which would cause an abnormal program termination.
