Does it make sense to do “try-finally” without “catch”?

Question

I saw some code like this:

    try
    {
        db.store(mydata);
    }
    finally
    {
        db.cleanup();
    }

I thought try

Answer 1

The finally block ensures that even when a RuntimeException is thrown (maybe due to some bug in the called code), the db.cleanup() call will be made.

This is also often used to prevent too much nesting:

try
{
    if (foo) return false;
    //bla ...
    return true;
}
finally
{
    //clean up
}

Especially when there are many points at which the method returns, this improves readability as anyone can see the clean up code is called in every case.
