- Project 2 statement ANSWER IN SINGLE FILE JAVAPlease read this entire statement carefully before you start doing anything… This project involves implementing a simple university personnel management program. The program contains three kinds of objects: Staff, student and faculty. For each object, the program stores relevant information such as university ID, name, etc. Different information is stored depending on the type of the object. For example, a student has a GPA, a faculty has a title and department (professor, mathematics).For each of any class data member, your program must include the getters and the setters, and each class must include at least two constructors. The goal of this Project is to demonstrate the use of inheritance, abstract classes, abstract methods, and method overriding. For a student, we need a: full name id gpa Number of credit hours currently taken For a faculty, we need a: full name id department (mathematics, engineering or english) Rank (professor or…Java code File IO ApplicationA shop collects the following information from its customers:1.

Most recent visit/service date7. Total amount charged8. Current balance and description of the last service You are to write a program that allow the shop to manage their customers.

Write syntax to generate a package to the different directory for the same class. Import the above generated package to your current class called “test_available” to get any three files names from the available class(list_avail_file) then read a line from each file one after another and display files content on the screen till the end and display totally how many lines are there in each files.
- java OverviewIn this assignment, you will create a class Publisher (publisher) and two test classes that create a number of different objects / instances of Publisher. The purpose of the task is to get acquainted with the concepts of object, class, method, constructor and overlay.TaskYou must write a class that represents a publisher (which will then be used in the next assignment). You rename the class to Publisher and are consequently saved in a source file called Publisher.java. The class must contain information about the publisher's name and telephone number.The operations we should be able to perform on objects of the class are to set and retrieve names and set and retrieve telephone numbers. It should also be possible to print all information about a publisher on the screen. In addition to this, the class must also contain a static instance variable for counting the number of created publishers, as well as a method that returns the number of created publishers.You should also…1 Preparation A Zip archive containing the files for the assignment is provided in Minerva. When you unzip it, you should see three files of earthquake data, along with four .java files. One of these, QuakeException.java, is complete and ready for you to use; the other three files containing empty Java classes. There are 'To Do' comments inside the classes that summarise the code that you need to write, and detailed step-by-step instructions are provided below. Before you begin programming, take some time to study the sample data. You can use a spreadsheet application to do this. Each row in the dataset represents a single earthquake. The different columns represent various parameters measured for an earthquake. You don't need to know what most of these are, although further details can be found at the USGS Earthquake Hazards Program website if you are interested. The only columns relevant to this assignment are: latitude, longitude, depth and magnitude. Note that filenames consist of…Write binary calculator java code using object-oriented programming concept. The calculator should +,-,* and / The calculator should convert from binary to decimal, then decimal to binary. The calculator should also apply for hexadecimal the same procedure as the binary calculator Use one of the four pillars of Object-oriented programming. And Don't only use the main method. https://www.calculator.net/binary-calculator.html
- Let's create our first Java file, called Welcome.java, which can be done in any text editor (like Notepad, Notepad++, Visual code, etc.). Open a file and paste the following Java code. public class Main { public static void main(String[] args) { System.out.println("mudau shudufhadzo welcome to BIS2142/ 2542 class"); } } Execute/ run it using a command prompt. Your output should contain a name and welcome to BIS2142/ 2542 class message. Therefore, your display message will look like this "mudau shudufhadzo "welcome to BIS2142/2542 class".Create an application that accepts employee data interactively. Users might make any of the following errors as they enter data: The employee number is not numeric, less than 1000 or more than 9999 The hourly pay rate is not numeric, less than R9.00 or more than R25.00 Create a class that stores an array of six usable error message that describe the preceding mistakes; save the file as EmployeeMessages.java. Create an EmployeeException class; each object of this class will store one of the messages. Save the file as EmployeeException.java. Create an application that prompts the user for employee data, and display the appropriate message when an error occurs. If no error occurs, display the message “Valid Employee data”. Save the program as EmployeeDataEntery.java (in java form)Please explain how the Java code is done File IO ApplicationA shop collects the following information from its customers:1.
