exception catch

if I have the following code

case A:
*****************************
try {

// do some stuff
} catch (IOException) {
// handle error
response.sendRedirect("/errorPage.jsp");
} finally {
jdbcConnection.close();
}
********************************

case B:
try {

// do some stuff
} catch (IOException) {
// handle error
return "IOException";
} finally {
jdbcConnection.close();
}
****************************************

My question is --- Will the "jdbcConnection.close()" be executed (i.e. closing the jdbc Connection) in both Case A and B when there is IOException raised ? (One is redirecting page and one is returning out of subroutine)

Yes, the call to close will execute in both of your provided cases.

finally is called irrespective of whether you return or not.So the connection is closed.

If finally is not called, you would have got an unreachable code error at compile time.
