Use BlueJ to write a java program that complete the following parts: "Employee" class: Create a class Employee and perform the following: - Define private fields (Ename, Eage, Edepartment) as (String, int, and String) respectively. - Define a class variable Salarythat holds a constant value 10000. · Define a parameterized constructor of the class Employeeto initialize the values of (Ename, Eage, E_department) as they are received in the parameters. Your "fullName group "class. Create your class and perform the following: - Declare a HashMap of employees where the Hashmap holds employees' id strings as its keys, and the values are the objects that are created by the class Employee. - Create a method to add an employee into the HashMap. The method receives two parameters, the employee id and employee object. Create a method to lookup an employee in the HashMap by employee id. The method receives the lookup key in the parameter.

2. Consider the following class, which represents a price in dollars and cents: class Price { private: int dollars; int cents; public: Price() { dollars = cents = 0; } Price(int d, int c) { dollars = d; cents = c; } Price operator+(Price&); void printer(); }; Implement the overloaded + operator to compute the sum of two Price objects, and return the result as a Price object containing the sum. You may assume that all price objects contain valid data, i.e. dollars>=0 and 0<=cents<=99.

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.
