Exercise 1: InheritanceExercise : Student worker inherited from worker

# workerName: String

# workerId: int

+ Worker(String, String, String )

+ getName(): String

+ setName(String): void

+ getId(): int

+ setId(int): void

+ getIsWorking(): boolean

+ setIsWorking (boolean): void

# hoursWorked: int

# isWorkStudy: boolean

+ StudentWorker(name: String, id: String, isworking:String, hoursworked: String, workstudy: String, payRate: String)

+ getPayRate(): double

+ setPayRate(double): void

Class Worker will represent the superclass. It should have fields to hold the following information:

workerName – the worker’s full name;

·          workerId – the worker’s assigned ID;

·          isWorking – True: the worker is employed, false is not;.

constructor method Worker accepts all three parameters as Strings and converts them to their appropriate primitive types;

Setter and getter methods for WorkerName;

·          Setter and getter methods for isWorking;

·          toString - returns WorkerName, WorkerId and isWorking as a string.

Class StudentWorker will be derived from the Worker class. It should have fields to hold the following information:

hoursWorked - The number of hours worked in the current two-week pay period.

·          isWorkStudy - True is the student having work permit; false otherwise

·          payRate - The student's hourly pay rate

·          constructor method accepts all six parameters as Strings and converts them to their appropriate primitive types

·          Setter and getter methods for payRate.

. toString - returns workerName,workerId, isWorking, hoursWorked, isWorkStudy, and payRate, as a string

Using the following code for your testing:

//Hint: you test program could be as:

StudentWorker s = new StudentWorker(“Chris Diez”, “123456”, “true”, “25”, “false”, “11.0”);

System.out.println(s.toString()); System.out.println(s.getName()); System.out.println(s.getId()); System.out.println(s.getPayRate()); System.out.println(s.setPayRate(18.00)); System.out.println(s.toString());

# workerName: String

# workerId: int

+ Worker(String, String, String )

+ getName(): String

+ setName(String): void

+ getId(): int

+ setId(int): void

+ getIsWorking(): boolean

+ setIsWorking (boolean): void

Explanation / Answer

package mani;

public class studentWorker extends Worker {
int hoursWorked;
boolean isWorkStudy;
double payRate;
   public studentWorker(String s1, String s2, String s3,String s4,String s5,String s6) {
       super(s1, s2, s3);
       hoursWorked=Integer.parseInt(s4);
       isWorkStudy=Boolean.parseBoolean(s5);
       payRate=Double.parseDouble(s6);
  
      
   }
   public double getPayRate(){
       return payRate;
   }
   public void setPayRate(double payR){
       payRate=payR;
   }
   public String toString(){
       return super.toString()+" Number of Hours Worked: "+hoursWorked+". IsWorking and Studying: "+isWorkStudy+". PayRate of Worker: "+getPayRate();
   }

}

package mani;
public class Worker {
String workerName;
int workerId;
boolean isWorking;
public Worker(String s1,String s2,String s3){
   workerName=s1;
   workerId=Integer.parseInt(s2);
   isWorking=Boolean.parseBoolean(s3);
}
public String getName(){
   return workerName;
}
public void setName(String name){
   workerName=name;
}
public int getId(){
   return workerId;
}
public void setId(int id){
   workerId=id;
}
public boolean getIsWorking(){
   return isWorking;
}
public void setIsWorking(boolean is){
   isWorking=is;
}
public String toString(){
   return "Name of Worker: "+getName()+". Id number of worker: "+getId()+". Is the Worker working still? "+getIsWorking();
}
}
