Create a class Rectangle with double attributes length and width. The default constructor should set these attributes to 1. Provide methods that calculate the rectangle's perimeter and area, as well as accessors and mutators for both data fields. The mutator methods for length and width should verify that the number being passed in is larger than 0.0 and less than 20.0 -- if it doesn't fit those criteria, the value of the field should not be changed. Write a Driver class in the same file to test your Rectangle class. It should prompt the user to enter a length and width of a rectangle, and then print out the area and perimeter of the rectangle. (Use the mutators to set the length and width of the rectangle, not the constructor.) SAMPLE RUN #1: java Driver Interactive Session Hide Invisibles Enter length of rectangle: 7.5. Enter width of rectangle: 3.04 Area: 22.5, Perimeter: 21.04 Highlight: Full Standard Output Show Highlighted Only O

Choose necessary patters, draw the UML and code just company class methods on paper. A car company makes a car produce application. There are diffrerent types of models that the company builds as sedan  and sport. Each model has some shared and distinguishing features. The object creation process should conduct by a central class. The second central class should not be created in the application.

Complete the FoodItem class by adding a constructor to initialize a food item. The constructor should initialize the name to "None" and all other instance attributes to 0.0 by default. If the constructor is called with a food name, grams of fat, grams of carbohydrates, and grams of protein, the constructor should assign each instance attribute with the appropriate parameter value. The given program accepts as input a food item name, fat, carbs, and protein and the number of servings. The program creates a food item using the constructor parameters' default values and a food item using the input values. The program outputs the nutritional information and calories per serving for both food items. Ex: If the input is: M&M's 10.0 34.0 2.0 1.0 where M&M's is the food name, 10.0 is the grams of fat, 34.0 is the grams of carbohydrates, 2.0 is the grams of protein, and 1.0 is the number of servings, the output is: Nutritional information per serving of None: Fat: 0.00 g Carbohydrates:…
