- 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".Hi... I am trying the Gladis Java (Starting Out with Java: From Control Structures through Data Structures (4th Edition) (What's New in Computer Science) ISBN: 9780134787961) chapter programming challenges (Chapter 6, 2PC, 17PC, and 18PC in particular) in java in netbeans and every time I have "public class Main", it throws an error, "class Main is public, should be declared in a file named Main.java" It asks to rename the file "Main". How do I get around this?

- I've posted this question multiple times and I've received the same answer every single time that does not even work. So can someone provide a correct answer this time please. Create a java program for an inventory system that allows the user to add products to the inventory that will be stored in a file, update product information, delete product information, insert new products along with their information, view a specific product, and view all products. Please include at least a one-sentence comment explaining what each line of code does. Store the following data on the products: Product Code - string Name - string. Short Description - string Long Description - string. Items in Stock - integer Unit price - floatThis assignment will help you to get started with NetBeans and using Java compiler: To begin, put a block comment at the beginning of your Java file (and every Java source file in the future) with the assignment number, assignment title, program author [your name], and the date it's due. Next, similar to the programs presented in the first chapter of the textbook, use System.out object to display the following information: Your first name The name of the operating system you are using The name of your project (or simply the folder name if not using the IDE) The name of the class that contains the main() method in your source file. Note: Your program should print each of the above items on a separate output line. "The name of the class that contains the main() method in your source file.public class MyClass { public static void main(String[]) { System.out.println( "Hi" ); }}Create a text file in Java, then Write complete Java code to Write the following text to Text file “Java is an object-oriented programming language" Finally, write Java code to read the text from the text file and display it on the jTextFields.
- 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.htmlWrite a Java program ( use ComputerAverage.Java as an example) that should implement an interactive dialog that provides user with information about the procedures and asks user for information. Create a new folder Hw2_Campbell which includes the following files assignment report file:Report_Area_Circumference.doc program’s source file: Area_Circumference.Java Program’s bytecode file: Area_Curcumference.In Java, create a program that asks the user for their first name, last name, address, city, zip, phone number, email, hourly rate, start date, end date, and number of hours worked. The program must consist of three classes, each one in its own file (I.e. Employee.java, PayPeriod.java) and called back to a main.java file. Classes named Employee, PayPeriod, and Payroll Manager. Employee gathers the info about the employee. PayPeriod gathers the payment info. PayrollManager computes and displays the info. PayrollManager should also use methods such as: double CalculateGrossPay(Employee, PayPeriod), double CalculateRegularPay(Employee, PayPeriod), double CalculateOvertimePay(Employee, PayPeriod), and void PrintPaystub(Employee, PayPeriod). output: ------------------------------------------Employee ID: 123456 Last Name: last First Name: first Hours Worked: 50 Hourly Rate: $10.00 Regular Pay: 40 hours at $10/hr: $400.00 Overtime Pay: 10 hours at $15/hr: $150.00 Gross…
- Hello, can you correct my codes, into inheritance please i am begging you help me. I badly needed it please Laboratory Exercise Guessing Game 2 Objective: At the end of the exercise, the students should be able to: Create a simple game that exhibits file input and output. Software Requirements: Latest version of NetBeans IDE Java Development Kit (JDK) 8 Procedure: 1. Create a folder named LastName_FirstName (ex. Reyes_Mark) in your local drive. 2. Create a new project named LabExer6A. Set the project location to your own folder. 3. Create a simple guessing game (similar to Hangman or Hangaroo). In this game, the user guesses a letter and then attempts to guess the word. 4. Create a Notepad file named words.txt which will store any number of words each written per line. 5. The Java program shall: • randomly select a word from the list saved in words.txt; • display a letter in which some of the letters are replaced by ?; for example, ED??A??ON (for EDUCATION);…2.2 Step 1: Make a File ReaderFor this step, you will only need to modify, and thusfocus on, the following class:• ReadShapeFile.javaFigure 1: Empty Window with a Title: Shape Booooi-iinggg FrameYou will also need to look at only the constructors ofthe following classes:• Circle.java• Oval.javaPretend the rest of the code does not exist. This is howwe break large programs into smaller components thata human can understand and work with. It’s also howthe rest of engineering works as well. Think about howthe parts of a car engine are compartmentalised nicelyinto components. You don’t need to hold the entirefunctionality of the engine in your head at one time– just the component you are working on and how itinterfaces with the rest of the system.It is very important that you only modify code in thefiles you are asked to modify. If your developmentenvironment suggests to change code outside thesefiles don’t do it – even if it makes things magicallycompile and the red text disappears.…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…
