Answer: There is in the java.lang.System

System.out.println(p);
to see what properties you can get(CPU among others)..
you then can:
 String prop = System.getProperty("aproperty(the CPU among other)");

Java application.
Answer:  There is!
execute a shell and then write the name of the shell script on the shells stdin stream.
Process child = rtime.exec("/bin/bash");
BufferedWriter outWriter = new BufferedWriter(new
OutputStreamWriter(child.getOutputStream()));
outWriter.writeLine("filename");
outWriter.flush();

Is there any way to manage Systray Icons with Java? I didn t even find anything in

call the program from Java with JNI.
