Your task is to develop a standard calculator in Java using BlueJ. Your implementation should use only following three packages: AWT, Swing and Util.Please implement the entire calculator within a single class. The GUI and the internal calculation logics should be separated under different methods. You may also choose to separate different parts of your code using sub-classes. This is what i should look like Please implement a GUI following the exact same layout as depicted in Fig. 1. In particular, the GUI should have the following components. • A display screen. The screen is to display the user inputs and the calculation outputs. The screen will display a digit “0” after the calculator is initialised. • A four-by-four grid with a total of 16 buttons. Among the 16 buttons, 10 of them correspond to the 10 digits, namely, 0, 1, 2, …, 9; four of them correspond to the four basic calculation operators, namely, addition (+), subtraction (-), multiplication (×) and division (÷); one is the…
Imagine that you’ve written a JavaScript constructor for a custom clownfish object with a position property and then added the following statements: clownfish.prototype.swimForward = function(distanceInCm) { this.position += distanceInCm; }; Now you would like to apply the swimForward() method to a similar custom object called lionfish. What statement(s) could you use to do this? a. You can call theswimForward()method only on objects of theclownfishclass because it is a private method. b. let spikey = new clownfish(); lionfish.prototype.swimForward.call(spikey, 50); c. let spikey = new lionfish(); clownfish.prototype.swimForward.apply(spikey, 50); d. let spikey = new lionfish(); clownfish.prototype.swimForward.call(spikey, 50);
Create a new Java project named Program 4 Three Dimensional Shapes. In this project, create a package named threeDimensional and put all 3 of the classes discussed below in this package Javadoc requires that every class, every field, every constructor, and every method have a general (useful) comment and all relevant tags. This includes @param tags for methods and constructors and @param and @return tags for methods. Create a Cube class with the following: 1 data member: an integer named lengthOfSide 2 constructors: a no-argument constructor that set lengthOfSide to 1 and one that takes lengthOfSide as an argument A getter and a setter for lengthOfSide A toString() method for Cube that simply returns the string "Cube: [lengthOfSide]" A getSurfaceArea() method that returns the surface area of this cube. A getVolume() method that returns the volume of this cube. Make sure to Javadoc EVERYTHING! Create a Sphere class that has everything that the cube class has except: Instead of…
In this Assignment we will build a simple graphical application that is responsive and that uses basic widgets and demonstrates event handling. The screen shot below shows the expected result In this Assignment we will build a simple graphical application that is responsive and that uses basic widgets and demonstrates event handling. The screen shot below shows the expected result You must not use any other library except tkinter. Your code must run on a standard machine. Your code must be written as a class that inherits from Tk and the application must resize gracefully. The apps must start in a usable state i.e. all the relevant values of the input widget must be set. So if you click ok when the app starts, then you should get the pop-up message shown in the last page. The reset button must set the app to the initial start state. Widget must align vertically as well as horizontally with their matching widget Application not designed as a class. Application not responsive: The…
Write a java program that may pass for a Basic Calculator with a graphical user interface and OOP paradigm. Your calculator should have functions for: addition, subtraction, multiplication, division, modulo, exponent function(^). Use oop technique and create a class called calculator that provide unique method body for each problem. Thus, your class should have six different method for these (addition, subtraction, multiplication, division, modulo, exponent function(^)) and use the GUI for user interaction.

This is the question I am struggling with - Create a class in JobApplicant.java that holds data about a job applicant. Include a name, a phone number, and four Boolean fields that represent whether the applicant is skilled in each of the following areas: word processing, spreadsheets, databases, and graphics. Include a constructor that accepts values for each of the fields. Also include a get method for each field. The get method should be the field name prefixed with 'get'. For example, the get method for name should be called getName. Create an application in TestJobApplicants.java that instantiates several job applicant objects and pass each in turn to a Boolean method named isQualified that determines whether each applicant is qualified for an interview. Then, in the main() method, display an appropriate method for each applicant. A qualified applicant has at least three of the four skills. This is the code it has given - public class JobApplicant { private String name;…
solve this java question SpecificationsWhat You Must ImplementYou must define a class named MediaRental that implements the MediaRentalInt interface functionality(index A). You must define classes that support the functionality specified by the interface. The followingspecifications are associated with the project:1. Define a class named MediaRental. Feel free to add any instance variables you understand are needed or anyprivate methods. Do not add any public methods (beyond the ones specified in the MediaRentalInt interface).2. The media rental system keeps track of customers and media (movies ,music albums and games). A customerhas a name, address as string , a plan and two lists. One list represent the media the customer is interested inreceiving and the second one represents the media already received (rented) by the customer. There are twoplans a customer can have: UNLIMITED and LIMITED. UNLIMITED allows a customer to receive as many mediaas they want; LIMITED restricts the media…
Write a program which controls a metro train and that keeps track of stations and who gets on and off. Design and implement a class called train, which has at least the following: At least the following attributes (you can include others): metroID stationNum which keeps track of the station that the train is at. iii. direction which keeps track of the direction the train is travelling in. passTotal which keeps track of the number of passengers currently on the train. A default constructor which sets the metroID to a random number between 1 and 1000, the station number to 0, the direction (int), and the passTotal to 0 (train is empty). A constructor with one parameter; the parameter is the metro id. The constructor assigns the passed integer to the metroID attribute; the rest of the attributes are set as described in the default constructor. Accessor methods for each attributes. Mutator methods for each attributes. nextStation(int lastStation) which determines the next…
