Java try catch finally seems pointless

Question

This is a quite silly question but i don't understand the combined use of catch and finally. As far as i know the code after a catch block will be executed whether or not an exception will be raised, so why using

try
{
    doSomething();
}
catch(Exception e)
{
    e.printStackTrace();
}
finally
{
    doSomethingInFinally();
}

instead of

try
{
    doSomething();
}
catch(Exception e)
{
    e.printStackTrace();
}

doSomethingInFinally();

? I always see people using the first pattern but i think it is extra code.

Answer 1

There are cases where your suggestion doesn't work

• There is no catch statement at all (the method will not continue executing if an exception is thrown).

• The catch block re-throws the exception.

• There is a return statement in the try block.
• The catch statement doesn't handle the super-type exception (like Throwable in your case).
