Why do we use finally blocks?

Question

As far as I can tell, both of the following code snippets will serve the same purpose. Why have finally blocks at all?

Code A:

try { /*          


        

Answer 1

Note that (in Java at least, probably also in C#) it's also possible to have a try block without a catch, but with a finally. When an exception happens in the try block, the code in the finally block is run before the exception is thrown higher up:

InputStream in = new FileInputStream("somefile.xyz");
try {
    somethingThatMightThrowAnException();
}
finally {
    // cleanup here
    in.close();
}
