Complete a properly encapsulated class named Rectangle, which inherits from Shape and has the following: Two double instance variable named width and length. A default, no-arg constructor which sets length to 2 and width to 1. An overloaded constructor which takes two double parameter and sets the instance variables width and length to the values passed in. Another overloaded constructor which takes four parameters, a double for width, a double for length, a boolean for isFilled and a String for color, and sets the instance variables accordingly, Hint:(Invoke the matching constructor from the superclass)!! Note that a rectangle has a length that is always greater than width. A void setLW() method which takes two parameters x and y, and set the length instance variable to the largest value passed in and the width instance variable to the smallest value passed in (Assume that x and y are always positive and have different values), also call this method in the constructors, so your instance variables will always have legal values. A method named getArea() which calculates and returns the area of the rectangle. An overridden toString() method. The returned String should contain: The value of the length, the value of the width, the area of the rectangle, then the result of calling the toString() method from the superclass, the return String should be formatted as follows: Width: 3.2 Length: 4.0 Area: 12.8 Filled: false Color: Red
