Unused parameters are misleading. Whatever the value passed to such parameters is, the behavior will be the same.

compute(a);

The following cases are ignored
|
||
|
|
* event handlers.
|
||
|
|
* overriding methods.
|
||
|
|
* all methods in classes implementing one or more interfaces.
|
||
|
|
* methods which are empty or where the body consists of a single comment or a single <code>throw</code> statement (i.e. where the intention is apparently to simulate an abstract class).
