Answer to Question #300801 in Java | JSP | JSF for terry

Question

In a particular factory, the team leader is an hourly paid production worker that 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 extends the Production Worker Class. The LeamLeader 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. Demo the class by using a program that uses the TeamLeader object.
