Java读取String分行字符串的方法

public static void main(String[] args) throws IOException{
 String s="1\r\n2\r\n3\r\n \r\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());
 }
