Wie man mit einem SIGTERM umgeht

Könnte man hinzufügen, eine shutdown-hook zu tun Bereinigung.

Wie diese:

public class myjava{
    public static void main(String[] args){
        Runtime.getRuntime().addShutdownHook(new Thread() {
        @Override
            public void run() {
                System.out.println("Inside Add Shutdown Hook");
            }   
        }); 

        System.out.println("Shut Down Hook Attached.");

        System.out.println(5/0);     //Operating system sends SIGFPE to the JVM
                                     //the JVM catches it and constructs a 
                                     //ArithmeticException class, and since you 
                                     //don't catch this with a try/catch, dumps
                                     //it to screen and terminates.  The shutdown
                                     //hook is triggered, doing final cleanup.
    }   
}

Führen es dann aus:

el@apollo:~$ javac myjava.java
el@apollo:~$ java myjava 
Shut Down Hook Attached.
Exception in thread "main" java.lang.ArithmeticException: / by zero
        at myjava.main(myjava.java:11)
Inside Add Shutdown Hook
