(The MyDate class) Design a class named MyDate. The class contains: The data fields year, month, and day that represent a date. month is 0-based, i.e., 0 is for January. A no-arg constructor that creates a MyDate object for the current date. A constructor that constructs a MyDate object with a specified elapsed time since midnight, January 1, 1970, in milliseconds. A constructor that constructs a MyDate object with the specified year, month, and day. Three getter methods for the data fields year, month, and day, respectively. A method named setDate(long elapsedTime) that sets a new date for the object using the elapsed time. Draw the UML diagram for the class and then implement the class. Write a test program that creates two MyDate objects (using new MyDate() and new MyDate(34355555133101L)) and displays their year, month, and day. (Hint: The first two constructors will extract the year, month, and day from the elapsed time. For example, if the elapsed time is 561555550000 milliseconds, the year is 1987, the month is 9, and the

Please in pyth coding with correct indentation 4a) Given that you have a Liquid class that can be initialized with any amount of gallons, liters, ounces, etc, write the first line of the method that will allow you to add together two Liquid objects using operator overloading. Again, write ONLY the first line (method definition) – you do NOT have to write the entire method. 4b) Given that you have L1 and L2 which are instances of the Liquid class, write a line of code that uses operator overloading to add them together and assign the result to L3.
State whether it is true or false and why .
1)Create a complete Java class that can be used to create a Computer object as described below:A Computer has a:- Manufacturer- Disk Size- Manufacturing Date- Number of coresa) Add all instance variables (data encapsulation is expected).b) The class must have getters and setters for all instance variables.c) The class must have two constructors: a no-arg constructor and a constructor thatreceives input parameters for each instance variable.d) Implement a toString() method for your class. 2)Write a Java program TestComputer, which creates three Computer objects with the informationbelow:a) - Manufacturer: Dell- Disk Size: 1189160321024 bytes- Manufacturing Date: April 1, 2020- Number of cores: 2b) - Manufacturer: Apple Inc- Disk Size: 269283712040 bytes- Manufacturing Date: March 31, 2020- Number of cores: 4c) Create your own Object.

In Python, write an initializer method that will be part of your class definition. The attributes will be initialized with parameters that are passed to the method from the main program.

50- What does it mean for an object to be "immutable"? a. The object can't be used in calculations. b. The object can't have its value changed. c. The object can't be passed as an argument to a function. d. The value of the object can't be accessed.
Indicate whether the statement is true or false. 13. The non-static methods of a class are called instance method. 14. A constructor has no type and is therefore a void method. 15. A class can have only two constructors. 16. In shallow copying, each reference variable refers to its own object. 21. The method finalize automatically executes when the class objects goes out of scope. 22. A mutator method of a class changes the values of data members of the class. 23. In java, the reference this is used to refer to only the methods, not the instance variables of a class. 24. Classes that are defined within other classes are called inside classes. 25. Modifiers are used to alter the behavior of the class 26. A constructor has the same name as the class. 27. Constructors are called like any other method. 28. You can perform some arithmetic operations on class objects.
1) Do you think it is possible to create another constructor with the same set of parameters? For example, adding the following constructor to Volunteer. Place a check (✓) beside your answer.Volunteer(): name_("Default"), branch_("CSU Long Beach") { } Yes, because you can overload constructors much like how you overload member functions. No, because the program will not know which constructor to use. No, because the body of the constructor is empty. 2) Much like constructors, member functions can also be overloaded. Write the name of Volunteer's overloaded member function. Take note that member function overloads need to have the same return type. 3) How do you think the compiler knows which member function overload it should call? Place a check (✓) beside your answer. It checks the name of the member function that was called. It compares the number of arguments and their data types with the member function's parameters. It always calls the overload with the least number of…
(Java) The Abstract Art Class Write an abstract class as follows: The class is named Art It inherits from the Comparable interface It has a private String member variable named name It has a private String member variable named artist It has a private int member variable called year It has a default constructor that assigns the values "No name" to name, "No artist" to artist and -1 to the year. This default constructor calls the three argument constructor. It has a three-argument constructor to assign values to the name, artist and year variables. It has a copy constructor that makes a copy of another non-null Art object It has getters and setters for the name, artist and year variables It has a toString() method that creates a string of artist, with name and year tabbed once on subsequent lines (see sample output) It has an equals method that compares this Art to another Object It has a compareTo method that compares in this order: 1) artist, 2) name, 3) year This class contains no…
Which of the following statements are correct? (Select all that applies.) Group of answer choices a) Inheritance is the process by which one object can acquire the properties of another object. b) "super" is used to access the method or member variables from the parent class. c) Constructors are used to initialize a newly created object. d) Method overriding occurs when a child class declares a method that has the same type of arguments as a method declared by one of its parent classes. e) An object that has more than one form is referred to polymorphism.
