通过Java编码获取String分行字符串的内容

代码案列：

import java.io.BufferedReader;
import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.nio.charset.Charset;

import net.sf.json.JSONObject;

public class Test {

    public static void main(String[] args) throws IOException {
         String s="11\r\n22\r\n33\r\n\nabd\r\n";  

BufferedReader br = new BufferedReader(new InputStreamReader(new ByteArrayInputStream(s.getBytes(Charset.forName("utf8"))), Charset.forName("utf8")));
         String line;
         StringBuffer strbuf=new StringBuffer();
         while ( (line = br.readLine()) != null ) {
             if(!line.trim().equals("")){
                 line="<br>"+line;//每行可以做加工
                 strbuf.append(line+"\r\n");
             }
         }
         System.out.println(strbuf.toString());  

    }

}

结果：

<br>11
<br>22
<br>33
<br>abd
