I want to create an application which provides GUI using a java swing but in that application i need to use terminal to execute the commands of Linux Ubuntu OS like sudo apt-get update and other.

Is there any method or code which executes my command in terminal but in background when I click on any button (on-click event) in form which is built using java swing?

You can also use ProcessBuilder class I used it one of my projects to execute commands in Linux(Fedora 18) to execute a particular process.

ProcessBuilder pb = new ProcessBuilder("ls");
Process p = pb.start();
p.waitFor();// This will wait untill the execution complets;

    Take a look at [ProcessBuilder](http://docs.oracle.com/javase/7/docs/api/java/lang/ProcessBuilder.html) Java Docs for more details – MadProgrammer Aug 16 '13 at 10:39
  • Also use `SwingWorker` (or equivalent) to read the IO streams without blocking the EDT. – trashgod Aug 16 '13 at 17:18

You can use Runtime.exec() methods to run commands. This creates a Process. You can then waitFor for your process to finish, read it's output for command's results, etc ...
Please see javadoc of java.lang.Runtime.exec and java.lang.Process
