Answer question Q2(a)-Q2(e) based on the information given in Figure Q2. A class named Rectangle contains: . Two double data fields named width and height that specify the width and height of the rectangle. A no-argument constructor that creates a rectangle with default value 1 for both width and height. (b) . . . A constructor that creates a rectangle with the specified width and height. A method named getArea () that returns the area of rectangle. A method named get Perimeter() that returns the perimeter of rectangle. A toString method that returns a string contains height, width, area of rectangle, and perimeter of rectangle. Figure Q2 Write a Java program to create class Rectangle. Implement all its attributes and methods. Write a Java program to create class MainRectangle. Implement method main in this class. Instantiate two Rectangle objects, one with default values and the other with width 4 and height 40. Display the width, height, area, and perimeter of each rectangle using toString() method.

Include both a constructor without any parameters and one with parameters for the description (String), cost (double) and weight (double) (in that order). For the constructor without parameters, set the description to an empty string, the cost to 0.0 and the weight to 0.0. Include appropriate accessor and mutator methods (and label them with comments including the terms "accessor" or "mutator"). So that the test cases compile, name the accessor methods: getDescription() getCost() getWeight() Additionally, name the mutator methods:…
