在不进行编码的情况下将字符串与字节数组相互转换

在不进行编码的情况下将字符串与字节数组相互转换

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);    }}
