java实现终止javaw.exe线程

public static void main(String[] args) throws IOException {
        Process process = Runtime.getRuntime().exec("cmd.exe /c tasklist |findstr \"javaw\"");
        Scanner in = new Scanner(process.getInputStream());
        while (in.hasNextLine()) {
            String p = in.nextLine();
            System.out.println(p);
            if (p.indexOf("javaw.exe") != -1) {
                StringBuffer buf = new StringBuffer();
                for (int i = 0; i < p.length(); i++) {
                    char ch = p.charAt(i);
                    if (ch != ' ') {
                        buf.append(ch);
                    }
                }
                // 打印 javaw.exe的pid
                String pid = buf.toString().split("Console")[0].substring("javaw.exe".length());
                // Runtime.getRuntime().exec("cmd.exe /c tskill " + pid);
                Runtime.getRuntime().exec("ntsd -c q -p 1528" + pid);
            }
        }
    }
