推荐答案

如果你正在处理异常，事情是非常简单的。 p>

If you're looking to handle the exception, things are pretty straightforward.

   public void exceptionFix1() {
       try {
           //code that throws the exception
       } catch (ExecutionException e) {
           //what to do when it throws the exception
       }
   }

   public void exceptionFix2() throws ExecutionException {
       //code that throws the exception
   }

请记住，第二个例子将被封装在一个 try-catch 块中的某个地方执行层次结构。

Keep in mind that the second example will have to be enclosed in a try-catch block somewhere up your execution hierarchy.

如果你想修复例外，我们必须看到更多的代码。
