Consider the following class definitions: public class BClass } private int x; public void set(int a) } X a; { public void print() } System.out.print(x); { { public class DClass extends BClass } private int y; public void set(int a, int b) } //Postcondition: x =a; y=Db; { public void print( ) {.…} a. Write the definition of the print method of DClass that overrides it. b. Write the definition of the method set of the class DClass.
- Consider the following class: public class theClass { private double value; private string str; public static int count; public theClass () { } public theClass (double d, int, x, String s) { } public void print() { } public static void incrementCount() { } } a) How many members do class theClass have? b) Compare the purpose of the two constructors. c) Use the reference this to write the definition of a method print( )to output the value of the instance data members separated by commas. d) Write a statement to create an object myClass of the class theClass and initialise the instance variables to 5, 10.75 and the string Class. e) Write a definition (heading) for a copy constructor for the class.public class date { private int day; // from 1 to 31 private int month; // from 1 to 12 private int year; // from 2000 upwards public void advance (); // move to next day }; Implement a constructor that initializes new objects of date class to be set to the 1st of January 2000. Implement setters for day, month, and year. Implement the advance method, which moves to the next day, ensuring that all data members are updated appropriately.public class Father { public String name; public int age; // customer name Father(){ name=”Hassan”; age=50;} public void display(){ System.out.println(“Name:”+name); System.out.println(“Age:”+age); } } 1. Based on Figure 3, create a class named Child that inherits the Father class. Declare an instance name location (String) for class Child. 2. Define a constructor in class Child and give an appropriate initial values for the instance (name, age, location). 3. Define a method display () in class Child, execute the display ( ) method in superclass using the keyword super. Method display ( ) in class Child should print the information of name, age and location 4. Create other class named Main for the main method and create 2 objects for the 2 classes (Father and Child). Then execute the display ( ) method for Father and Child. Example of the output as in Figure 4: Father's info: Name: Josh Age: 50 Child's info: Name: Christy Age: 20 Location:…

- Assume the Book class is defined as follows: public class Book{ enum Type type {FICTION,NON_FICTION}; public int isbn; public Type type; Book(int isbn, Type type){ this.isbn = isbn; this.type = type; }} Define filterBooksOfGivenType method that shall return ArrayList of Book of the type specified in parameter.Defining Classes Write and document the definition for the Money class. The Money class represents an amount in U.S. dollars. Money Class e Fields cents : int dollars : int e Methods getValue() : double Money(int d, int c) setCents(int c) : void setDollars(int d) : void toString() : String • Each Money object has two int instance variables: dollars and cents. • The class has one constructor that takes two int parameters. The first int represents whole dollars, and the second int represents cents. • The class has one accessor method named getValue() which returns the amount as a double. (Just divide cents by 100.0 and add it to dollars. Return that amount.) • The class has two mutator methods-setDollars() and setCents()–that modify the corresponding instance variables. • The class has a toString() method that returns the amount as a String in the form: $ 2345.75. Use concatenation to produce the output. Do not worry about the decimal places.Consider the following class definition for class named MyClass and answer the following questions. public class MyClass { /fields private int x; private int y; llconstructors public MyClass( ) {x = 0; y = 0; } public MyClass(int a, int b) { x = a; y = b; } I/methods public void ShowNumbers( ) { System.out.printin(x +* +y)B public void setx(int a) { x= a; public void sety(int b) { y = b; } public int getx() { return x; public int gety() { return y; public int getsum() { return (x + y); public int getproduct() { return x*y; } a) Declare an object named MyObject using no arg constructor. b) Declare an object named MyObject with 20 and 30 as arguments.
