Is finally block really necessary for the clean up code (like closing streams)?

Question

I am very confused as to why do I need to need to put the clean-up code like closing streams in a finally block.

I've read that the code in finally block will run no matter what (whether there's an exception); and after the finally block runs, the rest of the method continues.

My question is: if the rest of the method has to continue then why don't I put the clean-up code after my try/catch block in a function?

A finally block will do the job. But if you want to improve the security which avoids resources 'leaking' when the gc runs, I recommend you use try-with-resources it is neater and more efficient.
