捕获Exception类而不是Exception子类是不好的做法？ [英] Is it bad practice to catch the Exception class instead of Exception sub-classes?

问题描述

我有一个抛出Exception子类的方法。如果我为Exception的每个子类执行相同的catch功能，那么只是捕获E​​xceptions类或者我应该单独捕获每个异常是不好的做法吗？

I have a method which throws subclasses of Exception. If I am performing the same catch functionality for each sub-class of Exception that's causght is it bad practice to just catch the Exceptions class or should I catch each exception individually ?

推荐答案

是的，这是不好的做法，因为它会使catch块捕获不应被捕获的运行时异常。

Yes, it's bad practice, because it makes the catch block catch runtime exceptions that shouldn't be caught.

如果你使用Java 7，你可以使用

If you use Java 7, you can use

catch (SomeException | SomeOtherException | YetAnotherException e) {
    ...
}
