8) Now use the Rectangle class to complete the following tasks: - Create another object of the Rectangle class named box2 with a width of 100 and height of 50. Note that we are not specifying the x and y position for this Rectangle object. Hint: look at the different constructors) Display the properties of box2 (same as step 7 above). - Call the proper method to move box1 to a new location with x of 20, and y of 20. Call the proper method to change box2's dimension to have a width of 50 and a height of 30. Display the properties of box1 and box2. - Call the proper method to find the smallest intersection of box1 and box2 and store it in reference variable box3. - Calculate and display the area of box3. Hint: call proper methods to get the values of width and height of box3 before calculating the area. Display the properties of box3. 9) Sample output of the program is as follow: Output - 1213 Module2 (run) x run: box1: java.awt. Rectangle [x=10, y=10,width=40,height=30] box2: java.awt.…
I wrote my codes like this: public class OrderApp { public void main(String[] args) { FoodOrder foodOrder; } } public class Customer { private String name; public void chageCrditCard() { } } public class FoodOrder { Customer customer; private long orderNumber; public void addItem (MenuItem i) { } public double getTotalCost() { return 0.00; } } public class MenuItem { public String name; protected double price; public double getPrice() { return price; } } public class ComboMeal extends MenuItem { private double discount; public double getPrice() { return price; } public void addItem (MenuItem i) { } } I'm not sure If I did the relationship between classes and implement each one right. Also, how do I express multiplicities and specifiers in the codes? And finally, please review the whole thing. Subject: Java Programming
