I am writing a Java learning tool in Greenfoot. It's already working and I have this code.
to be called by these lines
Now, what I want to be able to do is, after the javac command, I'll run "java sample" inside a terminal.
I understand that going "cmd start java sample" only returns what is supposedly displayed on the cmd to the Greenfoot terminal. And by going "cmd start" ill just invoke a new cmd on the dir where my greenfoot project is at. (Since the target of our project is to teach Java to kids, I think it would be better if we need not include a documentation on how to manually run java on the console.)
I am on windows 7.
If anyone can point me to the right track or maybe give me a hint as to how ill be able to start my cmd already with java filename.. Please and Thank you

Process proc = Runtime.getRuntime().exec(cmd); //executes terminal command received
debug(cmd + ">", proc.getInputStream());
debug(cmd + "[ERROR]", proc.getErrorStream());

//System.out.println(cmd + " exitValue(): " + proc.exitValue());
}
public static void debug(String name, InputStream ins) throws Exception{
String line = null;
BufferedReader in = new BufferedReader(new InputStreamReader(ins));
while((line = in.readLine()) != null){
//System.out.println(name + " " + line);
System.out.println(line);
}
}try{
runProc("javac sample.java");
runProc("java sample");
} catch (Throwable t){
t.printStackTrace();}
