How do you catch multiple exceptions in a single catch?
Java allows you to catch multiple type exceptions in a single catch block. It was introduced in Java 7 and helps to optimize code. You can use vertical bar (|) to separate multiple exceptions in catch block.
Can we handle multiple exceptions in single catch block?

Can we have multiple try with single catch block in Java?

How many times you can write catch block?
Yes, we can write multiple catch blocks in a program , but the child exception (like NullRefernceException, OutOfIndexRangeException etc.) should be written first and the parent exception(i.e. Exception) should be written in last. But only one exception will be executed at a time.
Can we catch more than one type of exception in Java?
In Java SE 7 and later, we can now catch more than one type of exception in a single catch block. Each exception type that can be handled by the catch block is separated using a vertical bar or pipe |. Catching multiple exceptions in a single catch block reduces code duplication and increases efficiency.
Is it possible to catch multiple exceptions in one catch block?
However, to catch each exception, it needs to be done separately in their own catch blocks. Single catch block can handle more than one type of exception. However, the base (or ancestor) class and subclass (or descendant) exceptions can not be caught in one statement.
What is the catch clause in Java 7?
In the above Java 7 code the catch clause specifies the types of exceptions that the block can handle, and each exception type is separated with a vertical bar (|). This feature reduces code duplication and lessen the temptation to catch an overly broad exception.
Does catching multiple exceptions reduce code duplication in Java?
If you are catching multiple exceptions and they have similar code, then using this feature will reduce code duplication. Let’s understand java catch multiple exceptions feature with an example. Before Java 7, we used to catch multiple exceptions one by one as shown below.
