Java方法抛出异常 [英] Java method throwing exception
本文介绍了Java方法抛出异常的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
仅抛出异常
方法1:
public void myMethod()throws Exception1,Exception2,Exception3,Exception4,Exception5
{}
而不是方法1,我可以这样声明吗?
public void myMethod()throws Exception
{}
解决方案
是的,你可以定义。但是,方法调用者将会丢失一些有关引发的异常的信息。最佳做法是抛出特定的异常并专门处理。
I have a java method which is potent of throwing multiple unchecked exceptions. My question is: do I need to declare it to throw all the the exceptions or Is there any problem if I declare throws Exception
only?
Method 1:
public void myMethod() throws Exception1,Exception2,Exception3,Exception4,Exception5
{}
Instead of method 1, can I declare like this?
public void myMethod() throws Exception
{}
解决方案
Yes, you can define. But, method caller will loose some information about the exception thrown. Best practise is to throw specific exception and handle them specifically.
