Advantage of Local Classes Java

Question

What is the advantage of local classes in Java or in any other language that makes use of this feature?

Answer 1

There are a number of things that you can do with local classes that you don't get with anonymous inner classes.

• because the type has a name, you can more usefully add members not in the supertype
• a given name can make stack traces easier to follow (particularly for lock objects)
• subtype more than one base type
• construct in more than one place, and multiple constructors

On the other hand they make some hideously verbose syntax even messier.
