- Modify the student class presented in this chapter as follows. Each student object should also contain the scores for three tests. Provide a constructor that sets all instance values based on parameter values. Overload the constructor such that each test score is assumed to be initially zero. Provide a method called setTestScore that accepts two parameters: the test number (1 through 3) and the score. Also provide a method called getTestScore that accepts the test number and returns the appropriate score Provide a method called average that computes and returns the average test score for this student. Modify the toString method such that the test scores and average are included in the description of the student. Modify the driver class main method to exercise the new Student methods. (c++ language)Create the class Suitcase. Suitcase has things and a maximum weight limit, which defines the greatest total allowed weight of the things contained within the Suitcase object. Add the following methods to your class: A constructor, which is given a maximum weight limit public void addThing(Thing thing), which adds the thing in the parameter to your suitcase. The method does not return any value. public String toString(), which returns a string in the form "x things (y kg)" The things are saved into an ArrayList object: ArrayList<Thing> things = new ArrayList<Thing>(); The class Suitcase has to make sure the thing's weight does not cause the total weight to exceed the maximum weight limit. The method addThing should not add a new thing if the total weight happens to exceed the maximum weight limit. Below, you find an example of how the class can be used: public class Main { public static void main(String[] args) { Thing book = new Thing("Happiness…Create a Player class with a private name field and a guess method that returns an int representing the player's guess. Create a Game class with a number field representing the number the player has to guess, a maxAttempts field indicating the maximum number of attempts the player has, and a players list representing the players participating in the game. In the Game class, create a play method that does the following:a. Initialize the number of attempts to 0 and a boolean guessed flag to false.b. Loop while the number of attempts is less than the maximum number of attempts and the guessed flag is false: i. Loop through each player in the players list. ii. Call the player's guess method and compare the result to the number field. iii. If the guess is correct, set the guessed flag to true and print a message indicating the player who guessed the number. iv. If the guess is incorrect, print a message indicating that the guess was incorrect.c. Increment the number of…
- Create a class Course, which has one field: String courseName Create the constructor, accessor, and mutator for the class. Then, in the main method of this class, create an instance of the class with the name "CST1201". Write an equivalent while statement to replace the following for statement for (int i=2; i<100; i=i+2) { System.out.println(i); }JAVA PROGRAMMING Create a class named "Circle" that has attributes radius, area and circumference and make the attributes private. Make a public method that sets the radius and method that prints all attributes. Ask the user input for radius. Note: Use the PI from the math functions. Inputs: 1. A line containing an integer. 10 Output: Radius: 20 Area: 1256.64 Circumference: 125.66Create a Point class to hold x and y values for a point. Create methods show(), add() and subtract() to display the Point x and y values, and add and subtract point coordinates. Create another class Shape, which will form the basis of a set of shapes. The Shape class will contain default functions to calculate area and circumference of the shape, and provide the coordinates (Points) of a rectangle that encloses the shape (a bounding box). These will be overloaded by the derived classes; therefore, the default methods for Shape will only print a simple message to standard output. Create a display() function for Shape, which will display the name of the class and all stored information about the class (including area, circumference and bounding box). Build the hierarchy by creating the Shape classes Circle, Rectangle and Triangle. Search the Internet for the rules governing these shapes, if necessary. For these three Shape classes, create default constructors, as well as constructors…

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.Write a method toString() for the Cow class which displays information about a Cow object. The method should consider the following: • If the Cow's stomach value is 100, the output should say that the Cow is full • If the Cow's stomach value is below 100 but above 50, no information about the Cow's stomach should be given • If the Cow's stomach value is below 50 but above 10, the output should mention that the cow is hungry • If the Cow's stomach value is below 10, the output should mention that the cow is starving. Example output: First Cow is full. Second Cow Third Cow is hungry. Fourth Cow is starving!
- Create a rectangle class that can compute the area and the sum of its sides. 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! Note: All characters in boldface are user inputs.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…Create a method "public void giveRaise(int percentage)" in the Employee class. This method should increase the salary member by the percentage specified in the parameter. In the main method: 1. Create an Employee object. Print out its toString() result. Call giveRaise with 10%. 2. Print out its toString() result.
