How Can I Catch All Possible Exceptions in Java?

--
All exceptions come from the "mother class" called java.lang.Throwable and one of two subclasses called java.lang.Error and java.lang.Exception. A block of code that is executed when an exception occurs is called an Exception handler. By catching java.lang.Throwable, it is possible to handle all unexpected conditions. 
...
try {
}
catch(Throwable e) {
...
}
...
There are some special exceptions that used by the JVM, those are the sub-classes of java.lang.Error. We are not suppose the catch them in our real code and we usually catch java.lang.Exception for all application and runtime exceptions.
...
try {
}
catch(Exception e) {
...
}

    You know this is plain wrong, right? Pokemon exception handling is the worst thing you can do (about exceptions, obviously).

    Say you catch a Throwable and you want to rethrow it, you can call Thread.currentThread().stop(t). This triggers the current thread to throw the Throwable t. Note: this bypasses the compilers checked exception, so handle with care.

WebSphere MQ Interview Questions

What is MQ and what does it do? Ans. MQ stands for MESSAGE QUEUEING. WebSphere MQ allows application programs to use message queuing to participate in message-driven processing. Application programs can communicate across different platforms by using the appropriate message queuing software products. What is Message driven process? Ans . When messages arrive on a queue, they can automatically start an application using triggering. If necessary, the applications can be stopped when the message (or messages) have been processed. What are advantages of the MQ? Ans. 1. Integration. 2. Asynchrony 3. Assured Delivery 4. Scalability. How does it support the Integration? Ans. Because the MQ is independent of the Operating System you use i.e. it may be Windows, Solaris,AIX.It is independent of the protocol (i.e. TCP/IP, LU6.2, SNA, NetBIOS, UDP).It is not required that both the sender and receiver should be running on the same platform What is Asynchrony? Ans. With messag...

Advantages & Disadvantages of Synchronous / Asynchronous Communications?

  Asynchronous Communication Advantages: Requests need not be targeted to specific server. Service need not be available when request is made. No blocking, so resources could be freed.  Could use connectionless protocol Disadvantages: Response times are unpredictable. Error handling usually more complex.  Usually requires connection-oriented protocol.  Harder to design apps Synchronous Communication Advantages: Easy to program Outcome is known immediately  Error recovery easier (usually)  Better real-time response (usually) Disadvantages: Service must be up and ready. Requestor blocks, held resources are “tied up”.  Usually requires connection-oriented protocol
