只是浏览CompletableFuture文档并偶然发现了completeExceptionally和obtrudeException方法，并且很难理解差异和用例。社区可以通过示例帮助了解差异和用例吗？

完全异常：

completableFuture.completeExceptionally(
  new RuntimeException("Calculation failed!"));
//.. 
completableFuture.get(); //exception will be thrown whether `completableFuture` was not already completed.

突出异常：

completableFuture.obtrudeException(
  new RuntimeException("Calculation failed!"));
//.. 
completableFuture.get(); //exception will be thrown **whether or not** `completableFuture` was completed.
