    fooBar();
} finally {
    barFoo();

and

Answer 1

try {
    statements;
} catch (exceptionType1 e1) {      // one or multiple
    statements;                 
} catch (exceptionType2 e2) {
    statements;
}    
...
} finally {                                 // one or none
    statements;
}

1. All try statements must include either one catch clause or a finally clause
2. It can have a multiple catch clauses but only one finally clause
3. During any execution, if any errors occurs, then the Control is transferred to the appropriate Catch block and executes the statements and Finally block is executed.

No Matter what The Finally block is always executed, So in General, Finally block is used, when you have sessions, Database connections or Files or sockets are open, then the code for closing those connections will be placed. This is just to make sure in an application no memory leaks or Any other issues should not occur.
