包路径：com.google.common.util.concurrent.UncheckedExecutionException
类名称：UncheckedExecutionException

UncheckedExecutionException介绍

[英]Unchecked variant of java.util.concurrent.ExecutionException. As with ExecutionException, the exception's #getCause() comes from a failed task, possibly run in another thread.

UncheckedExecutionException is intended as an alternative to ExecutionException when the exception thrown by a task is an unchecked exception. However, it may also wrap a checked exception in some cases.

When wrapping an Error from another thread, prefer ExecutionError. When wrapping a checked exception, prefer ExecutionException.
[中]未经检查的java变体。util。同时发生的死刑例外。与ExecutionException一样，异常的#getCause（）来自失败的任务，可能在另一个线程中运行。
当任务引发的异常是未检查的异常时，UncheckedExecutionException是ExecutionException的替代方案。然而，在某些情况下，它也可能包装一个选中的异常。
当包装来自另一个线程的错误时，首选ExecutionError。包装选中的异常时，首选ExecutionException。
