Look at the Javadocs for System.exec()

just that i couldnt get that else where..i wanna implement a platform independent file tracker,so i gotta get the exec version for linux where i could run files in their own available default application. Can you help me???

Writing platform independent Java is easy. Writing platform independent software that uses platform specific tricks is nearly impossible.

And you have to ask hard questions such as:

What platforms to you care about?

Because if you mean PC and Linux, and not OS-X, you will get different answers than if you mean PC, Linux, OS-X, *BSD, AIX, HP-UX and others.

Once you have answered that, how about iPhone and other smart phones?

Additionally to words of fishtoprecords,if you want to use built-in commands from the OSes like DOS,Shell etc and to run them from Java,so you can do a platform independent if you check on which OS the program is running,so for checking create class constants:

Code:

/**
 * some handy constants that can be used throughout the program
 */
public class Constants {
    /**
     * the name of the OS as given by the Java system property "os.name"
     */
    public final static String osname = System.getProperty("os.name");
    /**
     * true if the program is running on OS X
     */
    public final static boolean isOSX = osname.equalsIgnoreCase("Mac OS X");
    /**
     * true if the program is running on Linux
     */
    public final static boolean isLinux = osname.equalsIgnoreCase("Linux");
    /**
     * true if the program is running on Solaris
     */
    public final static boolean isSolaris = osname.equalsIgnoreCase("SunOS");
    /**
     * true if the program is running on Windows Vista
     */
    public final static boolean isVista = osname.equalsIgnoreCase("Windows Vista");
    /**
     * true if the program is running on Windows
     */
    public final static boolean isWindows = !(isOSX || isLinux || isSolaris);
}

And then you can in another class to execute command line commands checking which os is that and then to put the proper command of course in order not to be given different answers from the system

Thank you,senior ...ll try out something which doesnt need any specific tricks..
