Final answer:
The doWork method in the Worker class might need to return a value for various reasons, such as providing a result for further processing or indicating the success of the work. The specific return type depends on the requirements and purpose of the method.
Step-by-step explanation:
The doWork method in the Worker class might need to return a value for various reasons. One common reason is that the method might need to provide some result or output to other parts of the program that call it. For example, if the doWork method performs a calculation, it might need to return the result of that calculation for further processing.
Another reason is that the method might need to indicate whether the work was successful or not. By returning a boolean value, for example, the method can inform the calling code whether the work was completed without any issues.
Ultimately, the specific return type of the doWork method will depend on the requirements and purpose of the method in the context of the program it is being used in.
