Generic remote access exception. A service proxy for any remoting protocol should throw this exception or subclasses of it, in order to transparently expose a plain Java business interface. When using conforming proxies, switching the actual remoting protocol e.g. from Hessian does not affect client code. Clients work with a plain natural Java business interface that the service exposes.
What is a remote exception in Java?
public class RemoteException extends IOException A RemoteException is the common superclass for a number of communication-related exceptions that may occur during the execution of a remote method call.

1. A simple RMI Application
In this example were are not going to dive deep into the RMI package, but we are going to create a simple RMI application in order to demonstrate java.rmi.RemoteException. This application will have a simple RMI server that provides an implementation of a remote method, as well as a client that can remotely call that method.
2. An example of java.rmi.RemoteException
Now, imagine that as your remote methods is executed, suddenly something goes wrong and it throws an exception. A java.rmi.RemoteException will be throw to the client.

How to handle Java exceptions?
Customized Exception Handling : Java exception handling is managed via five keywords: try, catch, throw, throws, and finally. Briefly, here is how they work. Program statements that you think can raise exceptions are contained within a try block. If an exception occurs within the try block, it is thrown. Your code can catch this exception (using catch block) and handle it in some rational manner. System-generated exceptions are automatically thrown by the Java run-time system. To manually throw an exception, use the keyword throw. Any exception that is thrown out of a method must be specified as such by a throws clause. Any code that absolutely must be executed after a try block completes is put in a finally block.

The argument, ExceptionType declares the type of the exception that it can handle and must be the name of the class that inherits from Throwable class.

StackOverflowError is an example of such an error.
What happens if an exception does not occur?
If exception occurs, then it will be executed after try and catch blocks. And if exception does not occur then it will be executed after the try block. The finally block in java is used to put important codes such as clean up code e.g. closing the file or closing the connection.
What is an exception in a program?
