Java中的字符串与字节流转换

直接代码，看后就明白：

 

public class StreamFromString {static String src = "今天的天气真的不好";public static void main(String[] args) throws IOException {byte[] buff = new byte[1024];//从字符串获取字节写入流InputStream is = new ByteArrayInputStream(src.getBytes("utf-8"));int len = -1;while(-1 != (len = is.read(buff))) {//将字节数组转换为字符串String res = new String(buff, 0, len);System.out.println(res);}}}
