You can execute any application by:-

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.InputStream;
import java.io.IOException;
class Main
{
public static void main(String[] args)throws IOException
{
    Process pr=Runtime.getRuntime().exec(args[0]);
    InputStreamReader isr=new InputStreamReader(pr.getInputStream());
    BufferedReader br=new BufferedReader(isr);
    String line="";
    while((line=br.readLine())!=null)
    {
        System.out.println(line);
    }
}
}

you can send argument to the application with specific path like c:\users\admin\vlc.exe. so it that it ll get executed..

    String key = "x", value = "c//as//xyx.exe";

    File application = new File(applicationName);

    if (application.exists()) {

        Process p = Runtime.getRuntime().exec(application.toString());
        p.waitFor();

    } else {
