ANSWER IN JAVA
Create a class called Date that includes three instance variables-a month (type int), a day (type int) and a year (type int). Provide a constructor that initializes the three instance variables and assumes that the values provided are correct. Provide a set and a get method for each instance variable. Provide a method displayDate that displays the month, day and year separated by forward slashes (/). Add a main method to the class that demonstrates class Date's capabilities.
JAVA HELP PLEASE! Write a class Rectangle that has only the following public methods (you can add other non-public methods if you think you need them):
Write a constructor that creates a rectangle using the x, y coordinates of its lower left corner, its width and its height (the parameters must be in that order). Creating a rectangle with non-positive width or height should not be allowed; throw an IllegalArgumentException for those cases. The values of x and y are allowed to be negative.
Write a method overlap(Rectangle other). This method should return true if this rectangle overlaps with other, false otherwise. Rectangles that touch each other are not considered to be overlapping.
Write a method toString that returns a String. The string should be formatted exactly as:“x:2, y:3, w:4, h:5”without the quotation marks and replacing the numbers with the actual attribute values of the object.
A class called Rectangle exists in Java already. You are not allowed to use this class in any…

9.12 LAB: Product class
In main.py define the Product class that will manage product inventory. Product class has three attributes: a product code, the product's price, and the number count of product in inventory.
Implement the following methods:
A constructor with 3 parameters that sets all 3 attributes to the value in the 3 parameters
set_code(self, code) - set the product code (i.e. SKU234) to parameter code
get_code(self) - return the product code
set_price(self, price) - set the price to parameter price
get_price(self) - return the price
set_count(self, count) - set the number of items in inventory to parameter count
get_count(self) - return the count
add_inventory(self, amt) - increase inventory by parameter amt
sell_inventory(self, amt) - decrease inventory by parameter amt
Ex. If a new Product object is created with code set to "Apple", price set to 0.40, and the count set to 3, the output is:
Name: Apple Price: 0.40 Count: 3
Ex. If 10…

Create a Die class with one integer instance variable called sideUp. Give it a constructor and a getSideUp() method that returns the value of sideUp and a void roll() method that changes sideUp to a random value from 1 to 6. [Note: To generate a random integer between 1 and 6, use Math.random() method] Then create a DieDemo class with a main method that creates two Die objects, rolls them, and then prints the sum of the two sides up.arrow_forwardThe following is a class definition for a simple Ebook. Two instance variables and one parameterless constructor are provided. Part 1: Write a second constructor that takes a String array of pages as input and sets the String array instance variable equal to the input. Continue to default the current page number to zero. Part 2: Write a getter and a setter method for the page number variable. The setter should check to make sure that the input is a valid page number and only update the variable if the new value is valid. Part 3: Write a getCurrentPage method that returns the String of the current page indexed by current_page. public class Ebook{ private String[] pages; private int current_page; //constructor public Ebook() { this.pages = {"See Spot.", "See Spot run.", "Run, Spot, run."}; this.current_page = 0; }}arrow_forward
- 16. Create a class SubstitutionCipher that implements the interface MessageEncoder, as described in the previous exercise. The constructor should have one parameter called shift. Define the method encode so that each letter is shifted by the value in shift. For example, if shift is 3, a will be replaced by d, b will be replaced by e, c will be replaced by f, and so on. (Hint: You may wish to define a private method that shifts a single character.)arrow_forwardSuppose you had a method named runThis that accepted a single integer as a parameter.

Do not override the makesSound() for your Dragon (bearded dragons don't make sounds!) Note, you'll also need a constructor in each of your subclasses which calls super(name) to initialize the common 'name' member of Animal. Next (in your test harness) create a List of different Animals ( a couple cats, a dog, a dragon... ) and add these Animals to your list. Iterate through your list & call makeSound on each.

- JAVA Method Overloading is a feature that allows a class to have more than one method having the same name, if their argument lists are different. Design a simple class and define a maximum method that finds the maximum of two integer values? Design an application to test that your new method is working properly. Now overload the maximum method to accept three double values and return the maximum of these three values? Finally overload the maximum method again such that it accept four double or four integer values and return the average of these four values? Modify your main( ) application to call and test these new methods. In each case the maximum overloaded methods should return the correct maximum values. Attach you java source codes and a screenshot of the output(s).arrow_forwardWrite a method toString() for the Cow class which displays information about a Cow object.

Create a specialized method that will allow the class to compare other rectangle objects. The comparison should identify the larger rectangle according to the object’s area. You should be able to implement the class where the user provides rectangle dimensions. The program should be able to display which of the rectangle inputs is larger using the Rectangle class method that you defined. Sample output: Enter Length R1: 1 Enter Width R1: 1 Enter Length R2: 2 Enter Width R2: 2 Results: R1 Area: 1 R1 Sum: 2 R2 Area: 4 R2 Sum: 4 R2 is the bigger Rectangle!

Write the following methods: • A constructor with just one parameter, the number of students; all grades can be randomly generated. • Accessor, mutator, toString, and equals methods. • A method returning an array of chars corresponding to the integer grades (90 or above should be converted to A, 80 or above to B, 70 or above to C, 60 or above to D, and 59 or less to F). • A method returning the number of A’s. • A method returning an array of int counting how many A’s, B’s, C’s, D’s, and F’s were received.arrow_forward
