Write a java program that uses 4 classes, Employee, Project, ProjectManagement, ProjectManagementApp. The classes are described below. You should name all data members and methods as shown below CLASS: Employee Download this class from Unilica and examine the data members and methods. the same) and false if not). Signature: public boolean equals(Object obi)) .Add an equals() method that compares two employee objects and returns true if they are equal (id is CLASS: Project Download the class from Unilica. The class already contains some data members and methods. Carefully review the code provided to you and complete the class by adding the following: . Data Members o o o static int projectCount- starts at 100, increments when project is created Employee projectManager ArrayList projectTeam (Employees) Methods o Constructor Takes projectName and duration as parameters. Initializes the data members to the parameters. Initializes an empty projectTeam. Sets the projectld and projectManager using the set method. " o Mutators for the following data members public setProjectManager - sets projectManager to Employee passed as parameter " private setProjectld sets the project id to "2017 - projectCount. Ex if projectCount is 120, the projectld is "2017-120". Should increment the projectCount after setting o addTeamMember0 " Takes an Employee as a parameter "If the Employee does not exist in the projectTeam, add the Employee (use the containsTeamMember method in your solution. Returns true if added successfully, false if not. " o estimateProjectCost0 Project cost is found by multiplying the average hourly wage for all Employees in the projectTeam by the duration (in hours) of the project
