- Problem No. 2 Write a Java class called ContainsInRange. This class defines a method called contains(), which takes as parameters an integer array a, an integer x, an int called start, as well as an int called end, and returns a boolean which is true if and only if x occurs in a at a position which is greater than or equal to start, and less than end. You must validate that start is less than or equal to end, and that both start and end are greater than or equal to 0, and less than or equal to a.length. Repeat the operation often. (please put also the code that the user can enter a value. Thank you)Assume ContractEmployee, HourlyEmployee, CommissionEmployee, FixSalaryEmployee are sub-classes of Employee class. Define the body of below method suchthat it shall print how many employees of each type the ArrayList object passed as parametercontains? Static void countAndPrintAllTypesOfEmployee (ArrayList employees) { }2) Consider the following class class Department { private: string name; const long locationNo; const longdeptId; intNumOfEmployees; static intnextDeptNo; static intnextLocationNo; public: Department( ); Department(string theName, totalEmps) void Print ( ) const; } Initialize both the values of nextDeptNo and nextLocationNo to 10000 Implement the default constructor to set the name to “Unknown”, locationNo to the current value of nextLocationNo, deptId to the current value of nextDeptNo and NumOfEmployees to zero. It should also increment the value of all static attributes by 1. Implement the other constructor to set the name and NumOfEmployees to the values that are passed to the contractor. The values of the locationNo and deptId should be assigned to the current values of nextLocationNo and nextDeptNo, respectively. This constructor should also increment the values of all static attributes by 1. The print function should print all values of all attributes (regular,…

Provide a constructor that enables an object of this class to be initialized when it’s declared. The constructor should contain default values in case no initializers are provided. Provide public member functions that perform the following tasks: Adding two Complex numbers: The real parts are added together and the imaginary parts are added together. Subtracting two Complex numbers: The real part of the right operand is subtracted from the real part of the left operand, and the imaginary part of the right operand is subtracted from the imaginary part of the left operand.

I it markets both book and audiocassette versions of its works. create a class called publication that stores the title (a string) and price (type float) and date of a publication. Provide getters/setters and constructor also write an abstract method isOversize() .From this class derive two classes: book, which adds a page count (type int); and tape, which adds a playing time in minutes (type float). Each of the classes should have a getter/setters and constructors and provide definition to function called isOversize() to the book and tape classes. Let’s say that a book with more than 800 pages, or a tape with a playing time longer than 90 minutes (which would require two cassettes), is considered oversize. You can access this function from main() and display the string “Oversize” for oversize books and tapes when you display their other data. explain the working in your words
