- In Java code: A company pays its employees on a weekly basis. The company has three types of employees: Salaried employees, who are paid a fixed weekly salary regardless of the number of hours worked; Hourly employees, who are paid by the hour and receive overtime pay; Commissioned employees whose pays are 20% of the week's sales Create a console-based object-oriented Java application that:Calculates weekly pay for an employee. The application should display text that requests the user input the name of the employee, type of employee, and the monthly salary, or hourly rate, if it’s an hourly employee, and hours worked for the week. For hourly employees, the rate will be doubled if it’s beyond 40 hours/week.The application should then print out the name of the employee and the weekly pay amount. In the printout, display the dollar symbol ($) to the left of the weekly pay amount and format the weekly pay amount to display currency. Implements a feature that allows the company to…In java Create a class called StudentAge. This class should allow the student to enter name and date of birth. After that, determine student age. Lastly, display student name, date of birth and age.TOPICS: Using Classes and Objects MUST BE IN JAVA. PLEASE USE COMMENTS AND WRITE THE CODE IN SIMPLEST FORM. 3. Write an application that reads the radius of a sphere then calculates and displays the circumference, volume and surface area. Use the following formulas, in which r represents the sphere’s radius. Print the output to four decimal places.Circumference = 2 π rVolume = 4/3 π r3Surface Area = 4 π r2 Hint: Section 3.5 of the textbook describes the many methods of the Math class and how they are used. The Math class also contains pre-defined constants like π. Search on the web for how you can use these. Testing: Include test exhibits for inputs that you choose. Make sure you check the results either with a calculator or some other independent source. Hint: Try Google!
- Objectives: Use Javadocs to document a class and methods Design and write a Java class Use fields (instance variables) Write multiple constructors Write accessor methods Write mutator methods Use the this keyword Use string concatenation Round floating point numbers (using Math.round()) Use a Scanner object Description ProduceItem class For this project, you get to design and write a ProduceItem class that stores a description, cost and weight as fields. Include both a constructor without any parameters and one with parameters for the description (String), cost (double) and weight (double) (in that order). For the constructor without parameters, set the description to an empty string, the cost to 0.0 and the weight to 0.0. Include appropriate accessor and mutator methods (and label them with comments including the terms "accessor" or "mutator"). So that the test cases compile, name the accessor methods: getDescription() getCost() getWeight() Additionally, name the mutator methods:…Create java code a new class called "Module" in which you add the following attributes: Code Name Number_students 2.Create another class called principle_program in which you create two instances of the class Module called ITP and POP. class principle_program { public static void main(String args[]) { //create two instances of the class Module } }TOPICS: Using Classes and Objects MUST BE IN JAVA. PLEASE USE COMMENTS AND WRITE THE CODE IN SIMPLEST FORM. 1. Write an application that prompts for and reads the user’s first and last name (separately), then displays a string composed of the first four characters of the user’s last name, followed by the first two letters of the user’s first name, followed by a random number in the range of 10 to 99. Assume that the last name is at least four letters long. Similar algorithms are sometimes used to generate usernames for new computer accounts. Testing: If the inputs were “Michael” and “Jackson,” the output should look like “JackMi42.” Include several tests with different inputs, including your own name.
- This 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" ); }}A class allows other programs to use a class s code through a. references b. objects c. methods O d. argumentsQ1: User Checker Build a java program that checks on a user who tries to change current password by asking some questions that user saved their answers while creating the account as shown below. The questions below use 5 different String class methods as follows: • What is your username? o Check if it's the same name saved regardless of capital/small letters • What is your password? o Check if it is written exactly the same as saved value • What is your favorite city? o Check if the city has o letter in middle • What is your brother age? o Compare the brother age to 20 • What is your luck number? o Check if the numeric value is > or < 0 Note: customize the answers of q1 & 2 as you prefer. Sample Runs (Success & Fail Scenarios): .....
- Create an object called Circle. Declare the following integer variables for the object Circle, radius, diameter, and pi is declared as double. Create the following for the Circle object: • Implicit constructor (default constructor) • Void method Calculate (double pi, int radius) to calculate the area of the Circle object. The method must include a system.out statement that displays the area value. Use the following formula to calculate area of the circle: Area = pi * (r* r) Your program includes a main class called Shape with a reference cl to the Circle object. Pass the following values to the object Circle: radius = 4 diameter = 8 pi = 3.14 Include output statements to view the values passed to the object Circle.java a. You want to create a Java main class. You create the source code file, declare the package, and write the class header. Now you must create the main method that starts the program. Write the entire method header, including the opening brace for the method. b. Assume that price is an integer variable whose value is the price (in US currency) in cents of an item. Write a statement that calculates the whole dollars in the amount and saves it in a new integer variable named dollars. Note: The Java style guide states that one space is used on either side of binary operators.Given two integers that represent the miles to drive forward and the miles to drive in reverse as user inputs, create a SimpleCar object that performs the following operations: Drives input number of miles forward Drives input number of miles in reverse Honks the horn Reports car status The SimpleCar class is found in the file SimpleCar.java. Ex: If the input is: 100 4 the output is: beep beep Car has driven: 96 miles // Simulates a simple car with operations to drive and check the odometer.public class SimpleCar { // Number of miles driven private int miles; public SimpleCar(){ miles = 0; } public void drive(int dist){ miles = miles + dist; } public void reverse(int dist){ miles = miles - dist; } public int getOdometer(){ return miles; } public void honkHorn(){ System.out.println("beep beep"); } public void report(){ System.out.println("Car has driven: " + miles + " miles"); } }
