Given the following code fragment

public class Point {

public int x; // Because these are public, you can access them public int y; // directly without getters and setters

```    };
public class Rectangle {
```
```        private Point ll; // the lower left corner of the rectangle
private Point ur; // the upper right corner of the rectangle
public Point getLLPoint() {return ll;}
public Point getURPoint() {return ur;}
```

}

1. (a) Write a method equals for the Rectangle class that takes a Rectangle as a parameter and returns true if two rectangles have the same area, and false otherwise

2. (b) Write a method manhattanDistance for the Point class that takes a Point object and calculates the distance between the current Point and the the given other Point assuming travel only along horizontal and vertical lines (e.g. between the manhattan distance between (0,0) and (1,1) would be 2)

public boolean equal_area(Rectangle r1,Rectangle r2){
int r1_length = r1.getURPoint().x - r1.getLLPoint().x;
int r1_breadth = r1.getLLPoint().y - r1.getURPoint().y;
int r2_length = r2.getURPoint().x - r2.getLLPoint().x;
int r2_breadth = r2.getLLPoint().y - r2.getURPoint().y;
if (r1_area == r2_area)
return true;
return false;
}
public int manhattanDistance(Point p){
return abs(p.x - x) + abs(p.y - y);
// abs is absolute value
}

Question 11 (20 points) Given the class Point below, define a class Circle that represent a circle with a given center and radius. The circle class should have a center attribute named center as well as a floating point radius attribute. The center is a point object, defined by the class Point. The class should also have these members: the constructor of the class, which should take parameters to initialize all attributes - a getter for center a setter for...
