Solved in 2 steps
- First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects).Then create a new Java application called "MinMax" (without the quotation marks) that declares an array of doubles of length 5, and uses methods to populate the array with user input from the command line and to print out the max (highest) and min (lowest) values in the array.PLEASE ENSURE TO USE THE FRAMEWORK PROVIDED IN THE IMAGES, AND THAT IT WORKS WITH THE TESTER CLASS. Write a class RangeInput that allows users to enter a value within a range of values that is provided in the constructor. An example would be a temperature control switch in a car that allows inputs between 60 and 80 degrees Fahrenheit. The input control has “up” and “down” buttons. Provide up and down methods to change the current value. The initial value is the midpoint between the limits. As with the preceding exercises, use Math.min and Math.max to limit the value. Write a sample program that simulates clicks on controls for the passenger and driver seats.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…
- Write a new snowflake class that extends AbstractShape. Your snowflake should be a unique and simple shape unlike any other student’s. Use the drawing methods provided in the imported Graphics class The SimpleSnowFlake is provided in the project as an additional reference. Add an equals(Object o) method that will compare unique instance variable data and return true if two of your snowflakes are the same. Your equals method should override the method from the Object class and call the equals method of AbstractShape Your snowflake should be a different color and move in a different and unique way.Please you can complete this part of my code almost done, I could not get the output. Please help me to fix this and add part 4 and 5. Part 4 instructions (please see image attached): Implement the relationship between interface and the classes as shown in the diagram below. You must correctly implement appropriate methods in your classesbased on abstraction and interface principles. Part 5 instructions: . Inside the main() method of the Watch class, do the following:a) Create a new instance of the “AnalogWatch” class using the overloaded constructorand assign it to the object reference of type “Watch”.b) Create a new instance of the “DigitalWatch” class using the overloaded constructorand assign it to the object reference of type “Watch”.c) Display the content of both the objects.d) Display the current time using the two objects created above respectively Code: public abstract class Watch { //Data Fields private String brand; private String material; private double…I need help with creating a Java program described in the image below: 9.26 LAB: Artwork label (classes/constructors) Given main(), define the Artist class (in file Artist.java) with constructors to initialize an artist's information, get methods, and a printInfo() method. The default constructor should initialize the artist's name to "unknown" and the years of birth and death to -1. printInfo() displays "Artist:", then a space, then the artist's name, then another space, then the birth and death dates in one of three formats: (XXXX to YYYY) if both the birth and death years are nonnegative (XXXX to present) if the birth year is nonnegative and the death year is negative (unknown) otherwise Define the Artwork class (in file Artwork.java) with constructors to initialize an artwork's information, get methods, and a printInfo() method. The default constructor should initialize the title to "unknown", the year created to -1. printInfo() displays an artist's information by calling the…
- First, launch NetBeans and close any previous projects that may be open (at the top menu go to File ==> Close All Projects).Then create a new Java application called "Parser" (without the quotation marks) that uses methods to:Get a comma-delimited String of integers (e.g. "4, 8, 16, 32") from the user at the command line and then convert the String to an ArrayList of integers (using the wrapper class) with each element containing one of the input integers in sequencePrint the integers to the command line, using a for loop, so that each integer is on a separate lineI need help with: The following is a class definition for a simple Ebook. Two instance variables and one parameterless constructor are provided. Part 1: Write a second Java constructor that takes a String array of pages as input and sets the String array instance variable equal to the input. Continue to default the page number to zero. Part 2: Write a getter and a setter Java method for the current page number variable. The setter should check to make sure that the input is a valid page number and only update the variable if the new value is valid. Part 3: Write a getCurrentPage method that returns the String of the current page indexed by current_page. public class Ebook { private String[] pages; private int current_page; //constructor public Ebook() { this.pages = {"See Spot.", "See Spot run.", "Run, Spot, run."}; this.current_page = 0; } }For the final take on this problem, we will use a class to solve the problem by reading the datafrom a text file. Prepare the text file as you wish if you can read it within your Java project.Name the 4Growth.txt. Don’t forget to close the file after you finish reading it!Create a new Java Project named PopCan04. Include a Jurisdiction class according to this UMLdiagram:You already have several pieces of its solution, the header is the same, the format specifiers arethe same, now, instead of using arrays, use an Array[] or an ArrayList<> of Jurisdictions toimplement the new solution. Be sure to include a method to calculate the population growth asdefines in the class diagram.Since you will be reading from a file, include a FileNotFoundException and catch it by printing amessage to the user: “File not Found.”The rest of the solution needs an enhanced for loop to produce the table. Finish by adding thefooter that you have been using all along. ***Population of provinces and…
- 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…Please answer the question posted and give full explanation of the answer.

I'm learning about the topics below and would love to see this program created so that I can get a better understanding for a later project. Please keep the class names the same as below and do not comment the code. I want to try and figure it out. You will have 4 different classes (please keep them separated as best as possible/use names provided below for classes): Multiset class: Make a multiset interface that does not extend anything. public interface MultiSet<AnyType> Test the MultiSet by adding Strings and test if duplicates are counted. TreeMultiSet class: It implements MultiSet but does not extend. Use private TreeMap<AnyType, Integer> map; (to look for any duplicates) override toString in the TreeMultiSet class.
