help you fix your problem No because the inner try block will not be reached when an exception occurs before and therefore the finally block is not reached either.

Workaround for python 2.4's yield not allowed in try block with finally clause

I hope this helps . I'm stuck on python2.4, so I can't use a finally clause with generators or yield. Is there any way to work around this? , You can duplicate code to avoid the finally block:
code :
try:
  yield 42
finally:
  do_something()
try:
  yield 42
except:  # bare except, catches *anything*
  do_something()
  raise  # re-raise same exception
do_something()

When should I use the finally-block in Java's try-catch-finally

this will help Use a finally block if you have code that must execute regardless of whether or not an exception is thrown.
Cleaning up scarce resources like database connections are a good example.

Proper usage of finally clause in try/catch block

I wish did fix the issue. Neither is correct. You shouldn't have a catch clause just to re-throw the exception again, clearing out its stack trace, and doing nothing productive, which is what your first option does.
You should just be closing in the finally:
code :
try
{
    _cmd.Open();        
    _cmd.Execute();
}
finally
{
    _cmd.Close()
} 
using(var command = ...)
{
    command.Open();        
    command.Execute();
}

How to avoid throw clause in finally block

I wish this helpful for you Your best shot is to use the Automatic Resource Management feature of Java, available since Java 7. If that is for some reason not available to you, then the next best thing is to replicate what that syntactic sugar expands into:
code :
public static void runWithoutMasking() throws MyException {
   AutoClose autoClose = new AutoClose();
   MyException myException = null;
   try {
       autoClose.work();
   } catch (MyException e) {
       myException = e;
       throw e;
   } finally {
       if (myException != null) {
           try {
               autoClose.close();
           } catch (Throwable t) {
               myException.addSuppressed(t);
           }
       } else {
           autoClose.close();
       }
   }
}

try/catch block return with finally clause in java

around this issue finally is executed before return statement. As java rule finally will always be executed except in case when JVM crashes or System.exit() is called.
Java Language Specification clearly mentions the execution of finally in different conditions:
