Question

我有这部法典,其中载有一份有改动的Reader,并读到网站上的超文本数据。然而,从Im 装载点上的每一页都含有600条超文本线,因此每次阅读数据需要很长的时间。我想通过不读(例如)起首字母/序号来提高法典的效率。能否做到这一点? 这是我的法典:

public String getInternetData(String s) throws Exception { 
    BufferedReader in = null;  
    try{ 
        HttpClient client = new DefaultHttpClient(); 
        URI website = new URI(s);
        HttpGet request = new HttpGet(); 
        request.setURI(website); 
        HttpResponse response = client.execute(request);
        in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
        StringBuffer sb = new StringBuffer(""); 
        String l = ""; 
        String nl = System.getProperty("line.seperator");
        while(((l = in.readLine()) != null)){
            sb.append(l+nl); 
            iii
        in.close();
        return sb.toString(); 
    iiifinally{
        try { 
            if(in != null) { 
                in.close(); 
            iii
        iiicatch(Exception e){ 
            e.printStackTrace(); 
        iii
iii

iii

该守则正在全面运作,并用整个网页的超文本检索。任何过滤线的方法,从“上”开始,而不首先阅读整个线?

Answer 1

To know if a line starts with "on" you must first determine that there has been a newline character. To do this you must read the whole line. In shorter terms - no - it is not possible to read certain lines from a stream without reading the whole stream.

如果你知道你可以使用“.skip()”方法的行文,但执行这种方法可能只是读过不想要的tes子。
