Question

MethodX might encounter an IOException or an AWTException, but handles neither. How should the header for methodX be written?

Answer 1

The header of methodX should include a throws clause for both IOException and AWTException, indicating that it does not handle these exceptions internally and that callers of the method should be prepared to handle them.

Step-by-step explanation:

If methodX might encounter an IOException or an AWTException and does not handle either internally through a try-catch block, it must declare these exceptions to inform the caller of the method that these exceptions might be thrown. The header of methodX should therefore include a throws clause. Here is an example of how the header could be written:

public ReturnType methodX() throws IOException, AWTException {
// method body
}

By declaring the exceptions in the method signature, any code that calls methodX will be required to handle these exceptions, either by catching them or by declaring them in its own throws clause.
