The finally keyword is used as a block to execute a given set of statements, whether an exception is thrown or not thrown. For example, if you open a file, it must be closed whether an exception is raised or not.SyntaxFollowing is the syntax −try {    // statements causing exception } catch( ExceptionName e1 ) {    // error handling code } catch( ExceptionName e2 ) {    // error handling code } catch( ExceptionName eN ) {    // error handling code } finally {    // statements to be executed }ExampleLet us see an example to implement ...
