如何计算java中算法的空间和时间复杂度.

执行的总时间[使用System.nanoTime()]是否等于任何算法或函数的时间复杂度？

示例:斐波纳契数列中第n个数的空间和时间复杂度估计

String对象如何在Java中工作？术语"不可变"如何完全适用于字符串对象？虽然我们在原始字符串对象值上操作,但为什么我们在通过某些方法后看不到修改过的字符串？

客户端:

    public List<String> post(List<String> toWrite){
        String result = "";
        List<String> allResults = new ArrayList<String>();

        try {
            openConnection();
            connection.setDoOutput(true);
            connection.setRequestMethod("POST");
            initializeOutputStream();
            for(int i = 0; i < toWrite.size(); i++){
                out.write(toWrite.get(i));
                out.newLine();
            }
            System.out.println(connection.getResponseCode());
            System.out.println(connection.getResponseMessage());
            initializeInputStream();
            while((result = in.readLine()) != null){
                allResults.add(result);
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            closeConnection();
        }

        return allResults;
    }

One of the attempts at the host:

    protected void doPost(HttpServletRequest req, HttpServletResponse resp)
            throws ServletException, IOException {
        // TODO Auto-generated method stub
        List<String> incoming = …
