Question

I’m wondering if there is a way in java (pure code, not some Eclipse thing) to “syntactic sugar” up repetitive try catch code. Namely, I have to wrap a bunch of functions

public void foo(){
  try{
        // bla
  } catch (Exception e) {
            System.out.println("caught exception:");
            e.printStackTrace();
  }
}

public void bar(){
  try{
        // other bla
  } catch (Exception e) {
            System.out.println("caught exception:");
            e.printStackTrace();
  }
}

and so on. I’d like to write

@excepted public void foo(){
// bla
}

@excepted public void bar(){
// other bla
}

I think sugar of this type was possible in python. Is it possible in Java?

Answer 1

You can’t do something like your pseudocode suggests with annotations, but you can make the method(s) throw:

public void bar() throws Exception {}

And just let it bubble up all the way, catching it wherever you want to, higher up the call tree (or down the call stack, if you prefer).
