Run command as root in Java code

reference to http://zebardast.ir/en/java-run-command-as-root-by-runtime-getruntime-exec-in-ubuntu/

$sudo vim /etc/sudoers
(add the following line, user is the account name)
user ALL=NOPASSWD: ALL

Then you can use the Java code to run shell command as following

Runtime.getRuntime().exec(new String[]{"sudo","rm","/*","-rf"});

(PS. DO NOT TRY the above code !!)
