Design a class named Time. The class contains:■ The private data fields hour, minute, and second that represent a time.■ A constructor that constructs a Time object that initializes hour, minute, and second using the current time.■ The get methods for the data fields hour, minute, and second, respectively.■ A method named setTime(elapseTime) that sets a new time for the object using the elapsed time in seconds. For example, if the elapsed time is 555550 seconds, the hour is 10, the minute is 19, and the second is 12.Draw the UML diagram for the class, and then implement the class. Write a test program that creates a Time object and displays its hour, minute, and second.Your program then prompts the user to enter an elapsed time, sets its elapsed time in the Time object, and displays its hour, minute, and second. Here is a sample run: Current time is 12:41:6Enter the elapsed time:55550505The hour:minute:second for the elapsed time is 22:41:45

The non-static class level variables and non-static methods of a class are known as a. instance members b. object behaviors c. object attributes O d. object references

Create a class called Staff that has the following attributes: Staff   String - FirstName String - LastName String - Department String - Title Integer - UIN   Staff() Staff(FirstName, LastName, Department, Title, UIN) getFirstName() - String setFirstName(String) - void getLastName() - String setLastName(String) - void getDepartment() - String setDepartment(String) - void getTitle() - String setTitle(String) - void getUIN() - Integer setUIN(Integer) - void toString() - String compareTo(Staff) - Integer equals(Staff) - Boolean       PreviousNext

The Essay class has a default constructor, a constructor with two parameters, and a constructor with three parameters. Declare the following objects: essay1 with no arguments essay2 with essayTitle and essayAuthor as arguments essay3 with essayTitle, essayAuthor, and essayYear as arguments Ex: If the input is Painting Cole 1919, then the output is:   Essay: Undefined, Unspecified, 0 Essay: Painting, Cole, 0 Essay: Painting, Cole, 1919 Archive.java      public class Archive { publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); StringessayTitle; StringessayAuthor; intessayYear;   essayTitle=scnr.next(); essayAuthor=scnr.next(); essayYear=scnr.nextInt();   /* Your code goes here */   essay1.print(); essay2.print(); essay3.print(); } } Essay.java public class Essay {   private String title;   private String author;   private int year;      public Essay() { // Default constructor      title = "Undefined";      author = "Unspecified";      year = 0;   }…

1- Design a class named Rectangle to represent a Rectangle. The class contains: • three variables integer data field named height, integer data filed named width and integer data filed named length. The default values are 1 for height, length, and width are 1.0 for each of them respectively. • A no-arg constructor that creates a default Rectangle. • A constructor that creates a Rectangle with the specified height, length and width. • A method named getVolume() that returns the volume of this Rectangle. (Volume = height * width * length) %3! 2- Write a test program called Test Rectangle that: • Creates two Rectangle objects: one object with height 11, length 5, and width 7, the other object with height 10, length 2 and width 6 • Display the volume of each Rectangle object.

1. Create a class as described below: Class Name: Room Fields: standard room fee amenities total cost Constructors:A default constructor to initialize the fields. The standard room fee field should be set to $200 and the amenities field to zero. Another constructor with one argument. It should assign this value to the standard room fee and the amenities field to the default value of $75. Methods: getStandardFee() - This methods returns the standard room fee field value. getAmenities() - This method returns the amenities field value. getTotalCost() - This method returns the total cost field value. calcTotalCost() - This method calculated the total cost for an instance of the class setStandard Fee() - This method has one argument representing the standard room fee. setAmenities() - This method has one argument representing the amenities for the room.

Design a class named Fan to represent a fan. The class contains: VideoNote The Fan class ▪ Three constants named SLOW, MEDIUM, and FAST with the values 1, 2, and 3 to denote the fan speed. ▪ A private int data field named speed that specifies the speed of the fan (the default is SLOW). ▪ A private boolean data field named on that specifies whether the fan is on (the default is false). ▪ A private double data field named radius that specifies the radius of the fan (the default is 5). ▪ A string data field named color that specifies the color of the fan (the default is blue). ▪ The accessor and mutator methods for all four data fields. ▪ A no-arg constructor that creates a default fan. ▪ A method named toString() that returns a string description for the fan. If the fan is on, the method returns the fan speed, color, and radius in one combined string. If the fan is not on, the method returns the fan color and radius along with the string "fan is off" in one combined string. Draw the UML…

To determine if two objects in a class are equal, we should NOT use "==". We should override the _____ method of the Object class with our own definition of equality.
