Suggestion from the author @linzee1 of article 深入理解 Future, CompletableFuture, ListenableFuture，回调机制. 💕

catching() methods of Guava ListenableFuture is best-practice, straightforward and convenient, nice.

According the naming convention of CompletableFuture, the implementing instance methods are:

catching/catchingAsync
catchingCompose/catchingComposeAsync

📝 Implementation Note

The position order of catching* method is before exceptionally* method. (because catching* method is more best-practice and straightforward.)
