It's been a while since I've used Java too, but I don't remember it requiring try..catch around ALL code. If you don't catch immediately, it defers the error to somewhere up the stack. This is what I meant by "ignoring" exceptions being the default behavior.

Shoopy gave the key term: checked exceptions. Your grandparent criticized unchecked exceptions, and gave praise to Go error handling for features found in checked exceptions.

There are obviously still non-trivial differences between checked exceptions and Go's error handling, but they aren't as world shattering as unchecked exceptions.

If you don't catch a checked exception in your code, then you need to pass the buck to your callers, by adding a "throws" clause into the method signature.
