In Java, is the “finally” block guaranteed to be called (in the main method)?

Question

I\'m a Java rookie and I was wondering, if I have the following typical Java code

public class MyApp {
  public static void main(String[] args) {
    try {
          


        

Answer 1

In a word, yes.

Code in the finally block in Java always executes unless:

• The JVM exits during the try or catch block
• The thread running the code is interrupted or killed during the try or catch block

(from: http://java.sun.com/docs/books/tutorial/essential/exceptions/finally.html)

So, unless you explicitly call System.exit(int), or kill the process or thread externally, you can rely on it.
