Objective: Write a class that will test dates and times inputted by the user and determine whether or not it is valid. This will focus on the usages of methods to organize code. First download the driver and put it in your project DO NOT ALTER THE DRIVER! Use this to run your project The driver : public class DateAndTimeDriver { public static void main(String[] args) { // TODO Auto-generated method stub DateAndTimeTester dtTester = new DateAndTimeTester(); dtTester.run(); } } Write a class file called DateAndTimeTester This DOES NOT have a main method Create the following methods run: This method returns nothing and takes no parameters. This is called by the driver and should handle all of the input from the Scanner and dialog for the user. isValid: returns true or false if a given String has the correct date and time. The String parameter should be formatted “MM/DD hh:mm” This method should call the methods isValidDate and isValidTime to determine this. isValidDate: returns…
a constructor that takes in an int, a string, and a double, constructor will assign them to the ID, name, and Averageinstance variables, then a no-argument (zero-parameter) constructor that will set the ID to the name to “No name assigned” and the Average to –1.0. With an accessor method for the name variable and a mutator method for the average variable. a toString() method that will display all three instance variables on a single line, with a " | " between each one. and then an equals() method that returns true only if all three instance variables are equal
(1) Add an __init__ method to the Widget class below. Each object of type Widget should have an instance variable called name and an instance variable called cost that represents a cost in dollars; those values are passed in when an object of type Widget is initialized. (2) Add a method to class Widget called is_cheap that returns True if the cost is less than $10, and False otherwise. (3) Add proper doctrings along with two examples for each method. You may use the Sample Usage code given below in your work.
Code In Java NetBeans Q: Create an Inventory system program which has the following classes: A) . A Date class that includes three instance variables, a month, a day, and an year. Provide a constructor that initializes the three instance variables, validating the values. Provide a toString method that displays the day, month, year separated by the forward slash(/).
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. (Java)

Please write code in JAVA Step 1: An Account class stores a current balance, and provides getBalance, deposit, withdraw, and toString methods in addition to at least one constructor. Add an account class to the project.Step 2: A CheckingAccount class extends the Account class and has additional attribute overdraft limit and additional method chequeDeposit. Implement the CheckingAccount class in the project. Make sure you add a constructor to the class.Step 3: Override the toString method in the CheckingAccount class to add the overdraft limit as well to the returned string.Step 4: A SavingsAccount class extends the Account class and has additional attribute interest rate and a method named addInterest to calculate and add the interest to the account. Implement the SavingsAccount class in the project. Implement the SavingsAccount class in the project. Make sure you add a constructor to the class.Step 5: Add a test class named AccountTester to the project and implement a main method in…

30. True or False: The parameterized constructors of Java does not accept any parameters instead, using these constructors the instance variables of a method will be initialized with fixed values for all objects. False True Give an explanation for the answer. Thank you
Overriding is useful when a method has the same signature and type as a method in the parent class. O a local variable has the same name as an instance variable. O you want to change the return type of a method. O a method has the same signature as another method in the same class.
Need an example of this format in java programming in eclipse Create a class 1. Define instance data fields 2. Define a constant properly; use the constant when needed 3. Define a constructor that receives parameters for instance data 4. Generate get and set methods for instance data (even though some methods may not be used) 5. Define 4 other methods • method one will not receive any parameters, but will return a value to the driver program • method two will receive one parameter, and will also return a value to driver program • method three will receive one parameter, and will also return a value to driver program • method four will receive 3 parameters from driver program and will be responsible for displaying all output B. Create a driver program 1. Instantiate objects passing specific data to the programmer written constructor 2. Call each of 3 methods, for each instantiated object, passing any required arguments, and saving any values being returned in a variable 3. Call the 4th…
java. Check ‘n Shop is a grocery supermarket in South Africa that provides a loyalty program to customers on a monthly basis. Customers earn points based on the number of visits and the amount they spend, especially on healthy foods during the month. The private data fields for the Shopper object class are: See attached image The constructor must assign values of the parameters to the private data field variables. The static variable should be incremented by one in the constructor. The increaseLoyaltyPoints() method calculates the number of loyalty points based on the amount a customer spent at the supermarket. All customers receive 100 free points each month. Use the following criteria to calculate the additional points earned to be added to the 100 free points: For every four rands (R4) spent, one loyalty point is awarded. Make use of an appropriate Math class function to round up the loyalty points to a whole number. The updateHealthLevel() method receive the total amount…
