import java.lang.Runtime;
import java.io.IOException;
public class loadNotepad
{
public static void main(String args[]) throws IOException 
        {
        Runtime load = Runtime.getRuntime();
        // getRuntime() method is a static method which is used to 
        // obtain access to an object of class Runtime.
        r.exec("C:\\windows\\notpad.exe");
        }
} // End of class loadNotpad
