字節數組怎么轉置？

1、string 轉 byte[]

String str = "Hello";

byte[] srtbyte = str.getBytes();

2、byte[] 轉 string

byte[] srtbyte;

String res = new String(srtbyte);

System.out.println(res);

3、設定編碼方式相互轉換

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();

}
