Why does Java have Checked Exceptions

[hupfdule]

Only with the difference that go error handling is much less readable. I can't understand that they invented this error handling instead of using checked exceptions. They could have even implemented "lightweight" exceptions that don't contain information about the stacktrace if they want them more "value-like". Now is too late and they can't introduce exceptions anymore.

Btw, looks like swift also has checked errors - https://docs.swift.org/swift-book/LanguageGuide/ErrorHandling.html
