Answer 1

//string 转 byte[]
String str = "Hello";
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 = "hello";
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();

}
