- Match the following: A class that contains no methods (other than constructors) that change any of the data in its object modifier means that there are no restrictions on where an instance variable or method can be used hiding implementation details is done by marking data and methods as When we call a method in Java using class type parameters Overloading is achieved when two or more methods in the same class have the same…arrow_forwardThe 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; }…arrow_forward1. Create a properly encapsulated class named Person that has the following: A String instance variable called name. A constructor that takes a String parameter and sets the instance variable. A properly named getter for the instance variable. A correctly overrided equals method which returns true if the name instance variable of the parameter and the reference variable calling the method are equal. (Do not forget the null and class type checks!) Compile your Person class. 2. Create a properly encapsulated class named Employee that inherits from Person and has the following: ● ● ● A String instance variable called office (e.g. "LWH 2222"). A String instance variable called hourlywage (e.g. "$45.15"). A constructor that takes three Strings as parameters for name, office, and hourlyWage and sets the instance variables of both the parent class and the Employee class. An overridden toString method that returns the concatenation of name and hourlyWage instance variables (separated by a…arrow_forward
- Explain........... A method defined within a class and whose header does NOT include the static modifier is known as which of the following? a class method b instance method c super method d private method e public methodarrow_forwardOverriding is useful when a method has the same signature and type as a method in the parent class. O a local variable has the same name as an instance variable. O you want to change the return type of a method. O a method has the same signature as another method in the same class.arrow_forwardThe class contains one constructor: public Account (double initBal, String owner, long number) which initializes the instance variables. 1. Overload the constructor as follows: public Account (double initBal, String owner) - initializes the balance and owner as specified; randomly generates the account number. public Account (String owner) - initializes the owner as specified; sets the initial balance to 0 and randomly generates the account number. public Account () - initializes the owner with empty string name; sets the initial balance to 0 and randomly generates the account number. 2. Overload the withdraw method that also takes a fee parameter and deducts that fee from the account. 3. Write a driver program that invokes all four versions of the constructors and two versions of the withdraw methods. Think about how the compiler can tell which method is invoked. Code: //*******************************************************// Account.java//// A bank account class…arrow_forward
