If you want to invoke some application, check out the Runtime and ProcessBuilder API.

Hi

I think the Runtime class encompasses the execution of native code. Runtime.getRuntime().exec("notepad.exe"); for example runs the notepad. Remember that either the exe is in the PATH or give complete path to it.

This exec() method returns a Process object through which you can have more control like killing the process itself.

The following is a sample program.

import java.io.IOException;

public class StartProcess {
	public static void main(String []args){
		try {
			Process p = Runtime.getRuntime().exec("notepad.exe");
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
}

And please read the JavaWorld article "When Runtime.exec() won't". Once you start with external processes, this article is a must-read.

The java.lang.ProcessBuilder class makes it easier, but it simplifies the problems discussed in the Daconta article Rob quoted. You still must read it.
