Return in try catch block. Correcty?

Is it possible to make something like that?:

try {
...
} catch (exception){

    return; // this is most important thing here. In catch block only "return"

}

Can I handle exception in this way - use only "return;"? It works fine, but I would like to know is it correct?

if you do something like this

public void someMethod(){
    try{
    ...
    } catch (Exception e) {
        return;
    }
}

You lose your exception.It's a bad practice, because if something goes wrong - you even won't be able to understand what's going wrong. Better ways

  • print error message to logs
  • rethrow this exception or your custom exception and process it on the next levels

It is correct syntax but as per java coding standards we must not swallow exceptions rather handle them in catch block or rethrow it with proper message

Yes, that's actually a valid use case. There are many valid reasons to return in the catch block, one of them being returning default values:

try {
    return service.getData();
} catch (SocketTimeoutException ex) {
    logTimeout(ex);
    return getCachedData();
}

This way you are ignoring the Exception, is it really want you want? It all depends on your context - it might be safe to do this (I doubt it, but hey, it's your code). Generally when some Exceptions happens - you should react, not by simply returning, but logging, defaulting (rarely a good option), retrying, etc.
