java - 如何将字符串转换为具有相同内容的byte[]

Question

我想将字符串转换为具有相同内容的字节[]。例子我有:

String str = "abc";
byte[] bytes;
//I want to convert "str" to "bytes" that they have same content:
(code here)
//after, print bytes -> "abc".

Answer 1

只要付出一点努力，你就可以达到这个目标。

所以我们要做的是使用getBytes方法

byte[] convertToBytes= stuff.getBytes("UTF-8");
String newString = new String(convertToBytes, "UTF-8");
