System.exit()
, Runtime.exit()
,
and Runtime.halt()
.
Invoking System.exit()
or Runtime.exit()
calls the shutdown hooks and terminates the currently running Java
virtual machine. Invoking Runtime.halt()
forcibly
terminates the JVM without causing shutdown hooks to be started.
Each of these methods should be used with extreme caution. Calls
to these methods make the calling code unportable to most
application servers.
Use the option to ignore calls in main methods.
