A java program, with a class Rectangle with attributes length and width , each of which defaults to 2. Provide methods that calculate the rectangle’s perimeter and area. It has set and get methods for both length and width . The set methods should verify that length and width are each floating-point numbers larger than 10.0 and less than 40.0. Write a program to test class Rectangle .

Write a public int method named initialNumberOfSticks which takes two int parameters named max_sticks and min_sticks and returns a random integer value between max_sticks and min_sticks (inclusive). You will create a new instance of the Random class and call it r. Use the nextInt method of r to a get random value within a desired range and use it to compute the value that will be returned. Your method must be a syntactically correct Java method.

Define a new “User” class that contains a username (string), a password(string) and user id number (integer). For example, a User can haveo “john”, “secret”, and 12345It should have at least the following methods:o toString method must return all the user information as a string inthe following format:NAME(user-name) PASSWORD(password) ID(user-id) such asNAME(john) PASSWORD(secret) ID(12345)o hasValidPassword method that checks and return true if thepassword is not the same as username or contains the user id.o isDuplicate that compares two User objects and return true if theyboth have the same user name and password and false otherwise.Important notes:o You can add as many other methods as you need. But this classshould not provide the default constructor.Show how this class being used to create User objects and how thesemethods are being called and return proper values   All data members must be declared as “private”• No global variable can be declared and used• Methods within the…

Write a Python class, Vehicle, that has three instance variables of type str, int, and float. These respectively represent the name of the vehicle, its year, and its price. Your class must include • a constructor method that initializes each variable to an appropriate value • methods for setting the value of each type, and retrieving the value of each type. method for printing the entire instance of a vehicle. Now define an instance of your class and test all the 4 types of methods including the constructor. .

in java 2.4. ProblemCreate a class called Exam that a teacher might use to represent an exam for a coursetaught in the university.An Exam should include different information as instance variables – an exam date(day, month, and year), an exam time (hour and minutes), and an exam max marks. Itshould also include 2 constants which are the exam type and exam order.The exam type value may be one of the constant static fields ("Lab Exam", "MidtermExam", "Final Exam") or any other value. The exam order (1, 2, 3, etc.) is set for labexams and midterms by using separate static counters, for other exam types is set to 0.

please write code in java Create a right triangle class with instance variables(double) for sideA, sideB and the hypo. write three constructors -the 2-param version assigns to sides A and B respectively. the 1-param version assigns the same value to both sides. the 0-param version assigns 10.0 to each side. the constructor also computes the hypotenuse based on the other two sides and saves that in the hypotenuse variable. Create accessors for all three variables. Write a toString() that will print/label the three sides. write some main code to create three instances of your class, one to test each of your constructors. you can input values or use fixed values. Display each instance using an implicit toString() call.

Define a new “Degree” class that contains a year (integer), a subject (string) and a person’s name (string). For example, a degree can haveo John Smith, 2020, Computer Science It should have at least the following methods: o toString method must return all the degree information: year,subject and person’s name in the following format:NAME(John Smith) SUBJECT(Computer Science) YEAR(2020)o hasTheSameDegree method that compares 2 degrees and returntrue if both have the same year and the same subject. Otherwise, itreturns false. Important notes:You can add as many other methods as you need. But this class should not provide the default constructor. Show how this class being used to create Degree objects and how these methods are being called and return proper values. All data members must be declared as “private” No global variable is allowed to be declared and used Methods within the class and the requested functions cannot have “cin” or “cout” but it should make use of parameters and…

Write a java class method named capitalizeWords that takes one parameter of type String. The method should print its parameter, but with the first letter of each word capitalized. For example, the call capitalizeWords ("abstract window toolkit"); will produce the following output: Abstract Window Toolkit

in java Given main(), define the Team class (in file Team.java). For class method getWinPercentage(), the formula is:wins / (wins + losses). Note: Use casting to prevent integer division. For class method printStanding(), output the win percentage of the team with two digits after the decimal point and whether the team has a winning or losing average. A team has a winning average if the win percentage is 0.5 or greater. Ex: If the input is: Ravens 13 3 where Ravens is the team's name, 13 is the number of team wins, and 3 is the number of team losses, the output is: Win percentage: 0.81 Congratulations, Team Ravens has a winning average! Ex: If the input is: Angels 80 82 the output is: Win percentage: 0.49 Team Angels has a losing average.

I have a Programming Question, The following is a class definition for a simple Ebook. So i need to write a second 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 current page number to zero. Part 2: Write a getter and a setter method for the 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. Here below are the two instance variables and one parameterless constructor that were provided   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;    }}
