If you aren't on java 7, you can extract your exception handling to a method - that way you can at least minimize duplication

<pre><code>try {
 // try something
}
catch(ExtendsRuntimeException e) { handleError(e); }
catch(Exception e) { handleError(e); }
</code></pre>

blocks|key|319318|text|对于Java+<7，您可以将if-else与Exception一起使用：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|319319|try+{
++++//+common+logic+to+handle+both+exceptions
}+catch+(Exception+ex)+{

}|code-block|syntax|javascript|319320|已编辑并替换了Throwable+with+Exception。|319321|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

For Java &lt; 7 you can use if-else along with Exception:

<pre><code>try {
 // common logic to handle both exceptions
} catch (Exception ex) {
 if (ex instanceof Exception1 || ex instanceof Exception2) {

 }
 else {
 throw ex;
 // or if you don't want to have to declare Exception use
 // throw new RuntimeException(ex);
 }
}
</code></pre>

Edited and replaced Throwable with Exception.

I'm making study cards, and this thread was helpful, just wanted to put in my two cents.

blocks|key|319418|text|在Java+SE+7发布之前，我们习惯于使用与try块相关联的多个catch语句来编写代码。一个非常基本的例子：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|319419|+try+{
++//+some+instructions
}+catch(ATypeException+e)+{
}+catch(BTypeException+e)+{
}+catch(CTypeException+e)+{
}|code-block|syntax|javascript|319420|但是现在有了Java的最新更新，我们可以在单个catch子句中处理多个异常，而不是编写多个catch语句。下面是一个示例，展示了如何实现此功能。|319421|try+{
//+some+instructions
}+catch(ATypeException%7CBTypeException%7CCTypeException+ex)+{
+++throw+e;
}|319422|因此，一个catch子句中的多个异常不仅简化了代码，而且减少了代码的冗余性。我找到了这篇文章，它很好地解释了这个特性及其实现。Improved+and+Better+Exception+Handling+from+Java+7这也可能对你有帮助。|offset|length|319423|entityMap|0|LINK|mutability|MUTABLE|url|http://www.coolcoder.in/2011/08/improved-and-better-exception-handling.html^0|0|0|0|0|1R|1E|0|0^^$0|@$1|2|3|4|5|6|7|W|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|X|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Y|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|Z|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|10|8|@]|9|@$M|11|N|12|1|13]]|A|$]]|$1|O|3|-4|5|6|7|14|8|@]|9|@]|A|$]]]|P|$Q|$5|R|S|T|A|$U|V]]]]

Before the launch of Java SE 7 we were habitual of writing code with multiple catch statements associated with a try block.
A very basic Example:

<pre><code> try {
 // some instructions
} catch(ATypeException e) {
} catch(BTypeException e) {
} catch(CTypeException e) {
}
</code></pre>

But now with the latest update on Java, instead of writing multiple catch statements we can handle multiple exceptions within a single catch clause. Here is an example showing how this feature can be achieved.

<pre><code>try {
// some instructions
} catch(ATypeException|BTypeException|CTypeException ex) {
 throw e;
}
</code></pre>

So multiple Exceptions in a single catch clause not only simplifies the code but also reduce the redundancy of code. 
I found this article which explains this feature very well along with its implementation.

This may help you too.

I need to catch two exceptions because they require the same handling logic. I would like to do something like:

<pre><code>catch (Exception e, ExtendsRuntimeException re) {
 // common logic to handle both exceptions
}
</code></pre>

Is it possible to avoid duplicating the handler code in each catch block?

Is it possible in Java to catch two exceptions in the same catch block?

我需要捕获两个异常，因为它们需要相同的处理逻辑。我想做一些类似的事情：catch (Exception e, ExtendsRuntimeException re) {    // common logic to handle both exceptions}是否有可能避免在每个catch块中重复处理程序代码？

问在Java中可以在同一个catch块中捕获两个异常吗？
