The finally Block
The finally Block
finally {
if (out != null) {
System.out.println("Closing PrintWriter");
out.close();
} else {
System.out.println("PrintWriter not open");
}
}- The finally block always executes when the try block exits. This ensures that the finally block is executed even if an unexpected exception occurs.

- Putting cleanup code in a finally block is always a good practice, even when no exceptions are anticipated.
