what happen to the exceptions when try used the finally only instead of catch and how it handles? [duplicate]

Question

when a programmer use a try block without catch

like this

    PersistenceManager pm = PMF.get().getPersistenceManager();
    try {
        pm.makePersistent(c);
    } finally {
        pm.close();
    }

what happen to exception and how it possibly handle later ?

I try learn it from internet but no clear result for it...

Answer 1

When you do not specify a catch block you are basically moving the responsibility of handling the exception to the caller of the method.

So if your method does not catch one or more Exceptions from the try block and an exception is raised in your method block it will be thrown back to the caller.

The finally block ensures that if something bad happens in the try block then at least you will have a chance to close/release any resources related before the exception is thrown back to the caller.
