Instructions: Implement the Java class Customer by following the UML class diagram provided below. Implementation details: The class constructor must receive the arguments in the following order: String firstName, String lastName, String address, String cardNumber, int pin, String username The password must be generated inside the class constructor by the class method generatePassword(). The password to be generated must meet the following criteria: Must have at least one numeric character. Must have at least one lowercase character. Must have at least one uppercase character. Must have at least one special symbol among @#$% Password length to be generated is fixed and equal to 12. Do please use SecureRandom() class to achieve randomness during password generation. toString() return value format must be as follows:Customer [firstName='John', lastName='Monkey', cardNumber='11336688', pin='1234', username='j.monkey', password='zF$7zR#1lFAo', address='453 Manin st,…
Problem:Write a program to simulate the work of processes scheduler by using RR algorithm. Theprogram should have three classes which are:1. Process Class: This class represents the process where it has process id, executetime and completion time. Arrival is assumed to be zero all times. Process id shouldbe unique and the class create it for each process. Provide the required methodsaccordingly.2. RRSchedule Class: This class represents the work of the scheduler. It has mainlytwo lists of processes, quantum size, and clock. One of the list will be as a recordof the processes while the other is to work on to execute the process in CPU. Theclock should be a simple counter to represent timing to run the list of processes.The method list should be as following:a. Pop method: to remove the process from the top of the list.b. Push method: to insert the processes at the end of list after it is interruptedand still has to go to CPU again.c. RunRR method: to represent the job of RR scheduler.…
Answer By True or False , JAVA LANGUAGE A Java interface can contain only constants and abstract methods. A class that implements an interface can define only the methods that are included in the interface. A static variable can be referenced only from a static method. Static variables are also called class variables.
Java Programming Object-Oriented Programming In an abstract class, write a factory method for creating a category of object of your choice (aside from furniture). Also, write the class representing that category.b) Write the child classes that are necessary to create 3 different types of objects that belong to that category
Help of what these errors mean. In C# • Create a Class, named Student, to hold properties of Student Last Name, Student First Name, Student ID (9 digits), Course Prefix and Number, and the tests (Test 1, Test 2, Test 3, Test 4). Create appropriate setter and getter accessors, and constructors. Use access modifiers. Example: First Name : Pat Last Name : Smythe Student ID : ABC111333 Course Prefix : CIST Course Name : 2431 Test 1 : 100 Test 2 : 90 Test 3 : 80 Test 4 : 88 • Prompt the user for the Student Last and First Name, Student ID, Course Prefix and Number and the tests. • Include at least one exception handling function. • Use an array to store the 4 test grades. • Use a looping structure to populate the array. • Calculate the numeric average based upon the 4 equally-weighted numeric grades. • Display all the data for each of student using a looping structure. • Display the numeric average for each student. • Create a function that will convert the numeric average to a…
Topic: C# Write the C# program with explaining the proper logic used and screenshot of the output which you got in Visual Studio... Difference between static and Instance class in C# Create some classes which implement the concept of method overloading and overriding. Read on difference between Abstract class and Interfaces and find out the example when to use what? Create classes with example of Abstract class and Interface.
Can class field manipulation be prevented?
A class type cast can be used to force an object reference to be converted into another object reference of a class type which is not the original type, or a subclass, of the object reference being type-casted. * True False
For each of the following two code sketches complete the following three steps: Use abstraction and information hiding to improve the design of the code sketch. Your answer should be in form of a code sketch (i.e., make the design clear by providing class names, method names, and examples of how classes and objects will be used). Do not construct an entire detailed program. Describe the negative consequences of poor use of abstraction and information hiding in each code sketch. Describe how your use of abstraction and information hiding avoids the negative consequences listed in the previous step. class Vehicle { } public enum FuelType { DIESLE, ELECTRIC, HYDROGEN, LNG, JET_FUEL } public FuelType fuelType; public void add Fuel (double amount) { if (fuelType == FuelType.DIESEL) { // code for adding diesel fuel... } else if (fuelType == FuelType.ELECTRIC) { // code for adding electric fuel... } else if (fuelType == FuelType.HYDROGEN) { // code for adding hydrogen fuel... } else if…
Explain the difference between the protected and public members of a class.
Implementation: After analysing the given requirements, implement the required application: with Object Oriented Programming style following the rules of good programming style (e.g. adding comments, etc.) using only the material covered in M251 (and its prerequisites) Hints: For each class, it is required to implement constructors, setters, getters, toString() method, and any other necessary method • If the user tries to do an operation that could violate the state of objects, the operation should be ignored and the application should display an error message (e.g. adding a worker to the same workshop twice, etc.) Checking equality of any 2 objects should be done via the equals() method There is a class that will do the main job of keep tracking of the workshops as follows: o t has one collection to store the whole data (all workshops of all product lines) It has static methods, one for each operation happens frequently For each adding or removing operation, a message should be…
Design, implement and test a class that can be used to hold information about a musical note. Test it with an appropriate driver program. DESIGN REQUIREMENTS A programmer MUST be able to set and retrieve the length of the note and the value of the note. [[ this means you must have setter and getter methods for your data fields.]] The length of a note may be a sixteenth note, eight note, quarter note, half note, or a whole note, [[ Feel free to code this however you like with a string, an integer, an enum... whatever you feel is best ]] The note's value is an integer. It is specified by counting how far the note lies above or below the A note that orchestras use in tuningLinks to an external site. In counting "how far", you should count every key, both the white and black notes on a plano. So the A note above middle C would have a value of 0. The A note one octave above that would have a value of 12. The default constructor should set a note to a A440 (an A note of frequency 440Hz)…
