java里面byte数组和String字符串转换
//string 转 byte[] String str = "问题"; byte[] srtbyte = str.getBytes(); // byte[] 转 string String res = new String(srtbyte); System.out.println(res);当然还有可以设定编码方式的
String str = "问题";
byte[] srtbyte = null;
try {
srtbyte = str.getBytes("UTF-8");
String res = new String(srtbyte,"UTF-8");
System.out.println(res);
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
