Question

In a particular factory, a team leader is an hourly paid production worker who leads a small team. In addition to hourly pay, team leaders earn a fixed monthly bonus. Team leaders are required to attend a minimum number of hours of training per year. Design a TeamLeader class that inherits from the ProductionWorker class. The TeamLeader class should have fields for the monthly bonus amount, the required number of training hours, and the number of training hours that the team leader has attended. Write one or more constructors and the appropriate accessor and mutator methods for the class. Demonstrate the class by writing a program that uses a TeamLeader object.

Answer 1

To design a TeamLeader class that inherits from the ProductionWorker class, the TeamLeader class should have fields for monthly bonus, required training hours, and attended training hours. This can be achieved by creating a TeamLeader class that extends the ProductionWorker class and includes the necessary fields and methods. The class can then be demonstrated by creating a TeamLeader object and using its methods to access and modify the attributes.

Step-by-step explanation:

TeamLeader Class

The TeamLeader class should inherit from the ProductionWorker class and include fields for the monthly bonus amount, required number of training hours, and number of training hours attended.

Here is an example of how the TeamLeader class could be implemented:

class TeamLeader extends ProductionWorker {
private double monthlyBonus;
private int requiredTrainingHours;
private int attendedTrainingHours;

public TeamLeader(String name, String employeeNumber, int shift, double hourlyPay, double monthlyBonus, int requiredTrainingHours, int attendedTrainingHours) {
super(name, employeeNumber, shift, hourlyPay);
this.monthlyBonus = monthlyBonus;
this.requiredTrainingHours = requiredTrainingHours;
this.attendedTrainingHours = attendedTrainingHours;
}

public double getMonthlyBonus() {
return monthlyBonus;
}

public int getRequiredTrainingHours() {
return requiredTrainingHours;
}

public int getAttendedTrainingHours() {
return attendedTrainingHours;
}

public void setMonthlyBonus(double monthlyBonus) {
this.monthlyBonus = monthlyBonus;
}

public void setRequiredTrainingHours(int requiredTrainingHours) {
this.requiredTrainingHours = requiredTrainingHours;
}

public void setAttendedTrainingHours(int attendedTrainingHours) {
this.attendedTrainingHours = attendedTrainingHours;
}
}

To demonstrate the TeamLeader class, you can create a TeamLeader object and use its methods to access and modify the attributes:

TeamLeader teamLeader = new TeamLeader("John Doe", "123456", 1, 20.0, 500.0, 40, 30);

double bonus = teamLeader.getMonthlyBonus();
int requiredHours = teamLeader.getRequiredTrainingHours();
int attendedHours = teamLeader.getAttendedTrainingHours();

teamLeader.setMonthlyBonus(600.0);
teamLeader.setRequiredTrainingHours(50);
teamLeader.setAttendedTrainingHours(35);
