java读取分行字符串

 

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="
"+line;//每行可以做加工
		    	 strbuf.append(line+"\r\n");
		     }       		    	 
		 } 
	     System.out.println(strbuf.toString());
	}
