The finally block executes
when the try block exits normally, or
when an exception occurs.
Therefore, the finally block always executes when the try block exits.
try {
} catch (ExceptionType name) {
} catch (ExceptionType name) {
} finally {
// always executes
}
The finally block is a key tool for preventing resource leaks. Place the code in a finally block when closing a file or recovering other resources
