下面是一个示例代码，将其转换
String到
byte array和回
String没有编码。
public class Test{ public static void main(String[] args) { Test t = new Test(); t.Test(); } public void Test() { String input = "Hèllo world"; byte[] inputBytes = GetBytes(input); String output = GetString(inputBytes); System.out.println(output); } public byte[] GetBytes(String str) { char[] chars = str.toCharArray(); byte[] bytes = new byte[chars.length * 2]; for (int i = 0; i < chars.length; i++) { bytes[i * 2] = (byte) (chars[i] >> 8); bytes[i * 2 + 1] = (byte) chars[i]; } return bytes; } public String GetString(byte[] bytes) { char[] chars = new char[bytes.length / 2]; char[] chars2 = new char[bytes.length / 2]; for (int i = 0; i < chars2.length; i++) chars2[i] = (char) ((bytes[i * 2] << 8) + (bytes[i * 2 + 1] & 0xFF)); return new String(chars2); }}
