使用CharBuffer和 InputStreamReader读取各种编码的网页

只要指明编码格式，就能正确的读取

import java.io.BufferedReader;import java.io.IOException;import java.io.InputStreamReader;import java.net.URL;import java.nio.CharBuffer;public class PageParser {public static void main(String args[]) {BufferedReader in = null;try {in = new BufferedReader(new InputStreamReader(new URL("http://news.cnool.net/0-1-19/35941/3.html").openStream(),"utf-8"));} catch (Exception e2) {e2.printStackTrace();}CharBuffer bos = CharBuffer.allocate(20480);int read = 0;StringBuilder sb = new StringBuilder();try {while (in.read(bos) != -1) {bos.flip();sb.append(bos.toString());}} catch (IOException e1) {e1.printStackTrace();}System.out.println(sb.toString());}}
