Write a class called Fraction.java; this class will be designed to handle
fractions. The Fraction class has only two instance variables:
u An integer numerator
u An integer denominator
The two instance variables can be publicly accessible (at this stage). Supply an input method for the Fraction class; this method will be used by the client to get a fraction (as two separate integer inputs) from the user. The input method should ensure that the denominator cannot be 0. Supply an output method for the Fraction class; this method will be used by the client to print out a fraction(as two separate integers) to the screen.
An output fraction would be in the form:
numerator / denominator
An example: the fraction for a half would be input as 1 for the first input and 2 for the second input. The output should be printed out as 1 / 2.
Once this is done, write a client class program called TestFraction.java; this
class is to be used to test Fraction class. The program should loop around getting fractions from the user and displaying them to the screen. Stop when the numerator is negative.
Note that the client program should use the Fraction class methods (via the dot notation) to read and display fractions. For example, pseudo-code to create a Fraction object and then use the input and output methods:
class TestFraction
public static void main(String[] args)
// create new fraction
Fraction frac = new Fraction()
// use dot notation to access methods
frac.input()
frac.display()

- Write an application TestStudent that prompts for and reads a student name. It then creates a Student object. It then prompts for and reads the number of quizzes n that the student has taken. It then prompts for and reads the scores of the student in n quizzes and adds each to the totalScore of the student using addQuiz() method. Finally, the application prints the student object using the toString() method, and it also prints his quiz average. The main method must handle java.util.InputMismatchException, java.lang.IllegalArgumentException and java.lang.Unsupported OperationException.In Java Write a Fraction class that implements these methods:• add ─ This method receives a Fraction parameter and adds the parameter fraction to thecalling object fraction.• multiply ─ This method receives a Fraction parameter and multiplies the parameterfraction by the calling object fraction.• print ─ This method prints the fraction using fraction notation (1/4, 21/14, etc.)• printAsDouble ─ This method prints the fraction as a double (0.25, 1.5, etc.)• Separate accessor methods for each instance variable (numerator , denominator ) in theFraction classProvide a driver class (FractionDemo) that demonstrates this Fraction class.

- Exercise 1: Write a Java application that simulates a test. The test contains at least five questions about first three lectures of this course. Each question should be a multiple-choice question with 4 options. Design a Test class. Use programmer-defined methods to implement your solution. For example: create a method to simulate the questions – simulateQuestion create a method to check the answer – checkAnswer create a method to display a random message for the user – generateMessage create a method to interact with the user - inputAnswer Display the questions using methods of JOptionPane class. Use a loop to show all the questions. For each question: If the user finds the right answer, display a random congratulatory message (“Excellent!”,”Good!”,”Keep up the good work!”, or “Nice work!”). If the user responds incorrectly, display an appropriate message and the correct answer (“No. Please try again”, “Wrong. Try once more”, “Don't give up!”, “No. Keep trying..”). Use…Using Java & Apache NetBeans Provide the screenshots for the OUTPUT Create a class named Customer that will determine the monthly repayment amount due by a customer for a product bought on credit. The class has five fields: customer name, contact number, product price, number of months and the monthly repayment amount. Write get and set methods for each field, except for the monthly repayment amount field. The set methods must prompt the user to enter the values for the following fields: customer name, contact number, product price and number of months. This class also needs a method to calculate the monthly repayment amount (product price divided by the number of months). Add a subclass named Finance_Period that will determine if a customer will pay interest or not. If the number of months to pay for the product is greater than three, the customer will pay 25% interest, else no interest applies. The maximum number of months to pay for the product is 12.

- Write java code for the test class named testAccount which contains: Main method Create this object of type account à number:30214 balance:950.23 Change the balance by using set method to 900.0 Print the object by using toString method.You will create a class for use in a video game in Python. The class will be named Player and will represent all the information about the player playing the game. In the constructor, the client passes a name, health, and strength for the player. Both the health and the strength should be between 1 and 100 (raise a ValueError if they are not). Include the following methods: attack: Generates a random number between 1 and the player's strength and returns that number. take_damage: has a parameter named damage_amount. This is how much the enemy is attacking the player for (this number should be between 1 and 100). Generate a random number between 1 and the damage amount, and that is how much the player blocks the attack for. Subtract the remaining attack from the player's health. This function should return True if the player has died from the attack (health gone below 0) and False otherwise. heal: Adds 10 to the player's health. If the players health goes above their start health, reset…The BankAccount class models an account of a customer.
