Question

Write a Java class named Employee to meet the requirements described in the UML Class Diagram below:

Employee Attributes private name: String private level: int Employee's name Employee's level Operations Employee : Employee Employee ( name: String, Default or null constructor Constructor accepting two (2) parameters, with String and int types. Returns a fully formed and fully functional Employee object reference level: int) Employee public setNaeaN ame:String :void public setLevel( alevel: int ):void Accepts a String object (local name: aName) and assigns it to the instance variable name Accepts a String object (local name: aLevel) and assigns it to the instance variable level Returns the current value of instance variable name Returns the current value of instance variable level public getN ame): String public getLevel() int public toString( ): String Returns a formatted String containing a 'state report, that is, the current values of each of the object's instance variables (L.e.name"in rank" +level"")

Note: Code added in the toString cell are not usually included in a regular UML class diagram. This was added so you can understand what I expect from you.

If your code compiles cleanly, is defined correctly and functions exactly as required, the expected output of your program will solve the following problem:

“An IT company with four departments and a staff strength of 7. Every year, the company allocates a budget of $100,000 to each department. However, this year the company has decided to increase the budget by an additional $800,000 for departments with employees with ranks equal to or greater than 4, and $400,000 to departments with employees with ranks less than 4. You are to write a program that shows a new total budget of each department”

All get and set methods must be ‘final’ methods.

The only direct access to instance variable values is through the set and get methods; no other direct access is ever permitted.

Your output need not be identical to that shown here, but you MUST include all instance values in the output, in the order shown:

Hulk Hogan in rank 8, Dwayne Johnson in rank 6,

Two test harness to use in testing your Employee.java code:

1)

public class TestOrg {

public static void main(String[] args) {

   initialValidation( );

   realValidation();

} // end main

    private static void initialValidation( )

{

    System.out.printf( "                 Beginning of Initial Class Testing %n" );

   

    // Instantiate one object of class using null constructor.  

    Employee checkEmployee = new Employee();

        checkEmployee.setName("Steve Austin");

        checkEmployee.setLevel( 8 );  

  

    // Use get methods to extract instance values

    System.out.printf( "Employee.name:     %s %n", checkEmployee.getName( ) );

    System.out.printf( "Employee.level:            %s %n", checkEmployee.getLevel( ) );

    System.out.printf( "                  End of Initial Class Testing %n%n%n" );

} // end intitalValidation

    private static void realValidation(){

      System.out.printf( "                Updated Class Testing %n" );

      //instantiate seven objects of employee class using constructor with arguments

   Employee hulk = new Employee("Hulk Hogan", 8);  

   Employee dwayne = new Employee("Dwayne Johnson", 6);  

   Employee john = new Employee("John Cena", 3);     

   Employee shawn = new Employee("Shawn Michaels", 7);  

   Employee big = new Employee("Big Show", 4);

   Employee tripple = new Employee("Tripple H", 7);  

   Employee brock = new Employee("Brock Lesnar", 4);

  

      //instantiate four objects of unit class using constructor with arguments

   Unit sales = new Unit("Sales Department");  

   Unit IT = new Unit("IT Department");

   Unit account = new Unit ("Accounting Department");

   Unit operation = new Unit ("Operations Department");

  

   //add employees to unit objects by passing the Employee objects as arguments

   sales.addEmployee( hulk );  

   sales.addEmployee( dwayne );

      

   IT.addEmployee(shawn);  

   IT.addEmployee(big);     

       

   account.addEmployee( john );

   account.addEmployee( tripple );

  

   operation.addEmployee(brock);

                          

    //this calls the descibe method per each unit object  

   sales.describe();  

   System.out.printf("%s%n", "----------------------------------------------------------------------------------");   

   IT.describe();

   System.out.printf("%s%n", "----------------------------------------------------------------------------------");  

   account.describe();  

   System.out.printf("%s%n", "----------------------------------------------------------------------------------");

   operation.describe();

    }

}

2)

import java.util.ArrayList; // Interface provides methods for manipulating objects by index

import java.util.List;      // Class implements interfaces List & Collection

public class Unit {

//instance variables

private String unitName;

private double budget;

private List emps = new ArrayList<>();

public Unit(String unitName){  

    this.unitName = unitName;  

   this.budget = 100000;

}   

public void addEmployee(Employee obj){

   emps.add(obj);  

   if(obj.getLevel() >= 4){

     this.budget += 800000;  

   }else{   

     this.budget += 400000;  

   } //end if statement

}  

public void describe(){   

   String temp = "The " + this.unitName + " has been allocated a total sum of " + this.budget

     + "\nbecause it currently has the following Employee(s) : ";  

   for(Employee x : emps){

     temp += x + " ";    }  

   System.out.println(temp);

}

}

Answer 1

Below is the code for your requirement. Please comment if you face any problem or if you want any modification.

Code:

=====

class Employee{

private String name = "";

private int level = 0;

public Employee() {

}

public Employee(String name, int level) {

this.name = name;

this.level = level;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public int getLevel() {

return level;

}

public void setLevel(int level) {

this.level = level;

}

@Override

public String toString() {

return "Employee name " + name + "in rank " + level;

}

}

Below is the output that I have got after integrating the above code in the main program and Unit program given in the question:

Output:

=====

Beginning of Initial Class Testing
Employee.name: Steve Austin
Employee.level: 8
End of Initial Class Testing

Updated Class Testing
The Sales Department has been allocated a total sum of 1700000.0
because it currently has the following Employee(s) : Employee name Hulk Hoganin rank 8 Employee name Dwayne Johnsonin rank 6
----------------------------------------------------------------------------------
The IT Department has been allocated a total sum of 1700000.0
because it currently has the following Employee(s) : Employee name Shawn Michaelsin rank 7 Employee name Big Showin rank 4
----------------------------------------------------------------------------------
The Accounting Department has been allocated a total sum of 1300000.0
because it currently has the following Employee(s) : Employee name John Cenain rank 3 Employee name Tripple Hin rank 7
----------------------------------------------------------------------------------
The Operations Department has been allocated a total sum of 900000.0
because it currently has the following Employee(s) : Employee name Brock Lesnarin rank 4
