try ,catch, finally execution

throws Exception in finally blocks

The catch block is only executed if an exception is thrown in the try block.
The finally block is executed always after the try(-catch) block, if an exception is thrown or not.

My question is IF I got Exception in finally block than how to handle it ?????

catch it and handle or throw it? Depends completely on your application. — Stephan, Aug 22 '12 at 15:00

You can throw an exception which results in a value returned (in either a catch or finally block) and you can return a value which results in an exception (from a finally block) — Peter Lawrey, Aug 22 '12 at 15:22

This is a well-known problem/gotcha in the Java language specification, in the sense that if an exception is thrown within the finally clause (without handling it in a nested try-catch) , the original exception gets lost. You will need to nest a new try-catch to catch the new exception, and process it there.

in java 7 there is a way to handle it. there is now a notion of "suppressed" exceptions where you can tie multiple exceptions together (see [Throwable.addSuppressed()](http://docs.oracle.com/javase/7/docs/api/java/lang/Throwable.html#addSuppressed%28java.lang.Throwable%29)). this was added for the new try-with-resources feature. – jtahlborn Aug 22 '12 at 15:09

+1 You have the same problem with throwing exceptions in the catch block. – Peter Lawrey Aug 22 '12 at 15:21

You have to handle Exception in finally block

like

finally{
    try
    {
       ///
    }
    catch(Exception e)
    {
      ///  
    }
}
