Retrieving a specific range of data from an array (Java)

I want to populate a ComboBox with the default 128 MIDI instruments, but calling Synthesizer.getDefaultSoundbank().getInstruments() returns a list of every instrument available (more than 400 on my machine).

I then copy the list of all the available instruments into an Object array (named _instruments), although it g开发者_如何学Goives me everything I could ever need, I only need the first 128 elements.

            _soundbank = _synthesizer.getDefaultSoundbank();
            _synthesizer.loadAllInstruments(_soundbank);
            _synthesizer.close();   
            _instrument = _soundbank.getInstruments();

Is there a specific way to get the first set of instruments or would it be possible to simply trim anything after the first 128 elements in an array? That way I would only be left with the first full set.

I hope that makes sense, it's an awkward scenario. Thanks!

The shortest and more comfortable way to do it would be using Arrays.copyOf. See below:

_instrument = Arrays.copyOf(_soundbank.getInstruments(), 128);

See the Javadoc for more info.

What about Java's own Arrays.copyOfRange(..) to extract the first 128?
