I had a job interview recently and I was supposed to do an exercise where one part of the coding was using the ExecutorCompletionService. Well, there were other ways, but this would have been the easiest.My problem : I did not know about this. After I found out about this, I could look it up easily (tutorials, examples, documentation, even source code)Could I have found this wrapper using online resources only? (I mean if I download the source code of the JDK, I can used a normal IDE to look for usages of classes, but can I do this online?)
How to look for wrappers (decorators) of specific classes?
