Here you go (JAVA) :

    try {
        int ch, processorCount = 0;
        Process process = Runtime.getRuntime().exec("cat /proc/cpuinfo");
        StringBuilder sb = new StringBuilder();
        while ((ch = process.getInputStream().read()) != -1)
            sb.append((char) ch);
        Pattern p = Pattern.compile("processor");
        Matcher m = p.matcher(sb.toString());
        while (processorCount.find())
            processorCount++;
        System.out.println(processorCount);
    } catch (IOException e) {
        e.printStackTrace();
    }
