How To Throw Multiple Exceptions In Java

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 Java 7 instead. Use multi-catch syntax Java 7

Multiple Catch Block in Java. Starting from Java 7.0, it is possible for a single catch block to catch multiple exceptions by separating each with pipe symbol in the catch block. Catching multiple exceptions in a single catch block reduces code duplication and increases efficiency.

In Java 7, catch block has been improved to handle multiple exceptions in a single catch block. 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. Java catch multiple exceptions

Catching base Exception. When catching multiple exceptions in a single catch block, the rule is generalized to specialized. This means that if there is a hierarchy of exceptions in the catch block, we can catch the base exception only instead of catching multiple specialized exceptions. Let's take an example. Example 3 Catching base exception

A catch block that handles multiple exception types creates no duplication in the bytecode generated by the compiler the bytecode has no replication of exception handlers. Rethrowing Exceptions with More Inclusive Type Checking. The Java SE 7 compiler performs more precise analysis of rethrown exceptions than earlier releases of Java SE.

In Java, we may have to deal with multiple exceptions. It is not possible to throw numerous exceptions in Java. We can specify multiple exceptions, but only one of them will be thrown. However, we have a few alternatives that we may use to simulate throwing multiple exceptions. We can use chained exceptions for dealing with multiple exceptions.

To throw multiple exceptions in Java you'll first have to suppress each exception into one customized exception and then throw the same customized exception. Please check the below code snippet to achieve the same. public class AggregateException extends Exception public void addExceptionException ex addSuppressedex exception true

The advanced techniques which are used in Handling Multiple Exceptions are Multi-catch Feature in Java 7 Single Catch Block Catch multiple exception types in a single catch block using the multi-catch feature. Code Conciseness Enhances code readability and reduces redundancy by handling multiple exceptions in one block.

Exceptions Thrown. Java throw keyword is used throw an exception explicitly in the code, We are allowed to throw only one exception at a time i.e. we cannot throw multiple exceptions.
