Order matters here. Arrange your catch blocks from most specific to most general. Java uses the first matching catch block, so if you were to put Exception first that would catch everything. If you handle multiple exceptions in the same way, consider using the multi-catch feature available in...
So far we have seen how to use a single catch block, now we will see how to use more than one catch blocks in a single try block. In java, when we handle more than one exceptions within a single try {} block then we can use multiple catch blocks to handle many different kind of...
Here, we are demonstrating the multiple "catch" blocks., The program may generate a different kind of exceptions according to the input values of variables, and then we handle the exceptions using the "catch" block. C# program to demonstrate the multiple catch blocks in exception handling ...
As you can see that inrethrowmethod, catch block is catching Exception but it’s not part of throws clause. Java 7 compiler analyze the complete try block to check what types of exceptions are thrown and then rethrown from the catch block. Note that this analysis is disabled if you change...

In Java SE 7 and later, a singlecatchblock can handle more than one type of exception. This feature can reduce code duplication and lessen the temptation to catch an overly broad exception. Consider the following example, which contains duplicate code in each of thecatchblocks: ...
