Runtime Environment + Linux + the "find" command

Question

Hi everybody,
I want to write a small program which makes it easy for me to use the find command with Linux. I have experience with Java but I have never used the runtime environment before. I am not sure how to best execute the "find" command. I tried this:
    public static void main(String[] args)
        String command = "find -name \"*\"";
        execute(command);
    private static void execute(String p_command)
        // Show the executed command.
        System.out.println(p_command);
        // Get the runtime object and handle the command.
        Runtime rt = Runtime.getRuntime();
        try
            // Execute the command.
            Process proc = rt.exec(p_command);
            // Show the output of the command.
            InputStream stdin = proc.getInputStream();
            InputStreamReader isr = new InputStreamReader(stdin);
            BufferedReader br = new BufferedReader(isr);
            String line = null;
            System.out.println("<OUTPUT>");
            while ( (line = br.readLine()) != null) System.out.println(line);
            System.out.println("</OUTPUT>");
            // Show the exit value of the process.
            int exitVal = proc.waitFor();
            System.out.println("Process exitValue: " + exitVal);
        catch (Exception e)
            System.out.println("Could not excecute: " + p_command);
    }This piece of code returns this:
find -name "*"
<OUTPUT>
</OUTPUT>
Process exitValue: 0This is not correct, because it should return something like this:
[jethro@laptop FindNix]$ find -name "*"

It looks like you doing all correctly. I don't know what does Runtime.exec() do with passed arguments, but if specify command in following way:
String command = "find -name *";
'find' executed through Runtime.exec() behaves as if it was executed from command line with arguments -name "*".
