Java中char与byte的互转

char[] 数组转为byte[] 数组

public static byte[] getBytes(char[] chars) {

Charset cs = Charset.forName("UTF-8");

CharBuffer cb = CharBuffer.allocate(chars.length);

cb.put(chars);

cb.flip();

ByteBuffer bb = cs.encode(cb);

return bb.array();

}

byte[] 数组转为数组 char[]

public static char[] getChars(byte[] bytes) {

Charset cs = Charset.forName("UTF-8");

ByteBuffer bb = ByteBuffer.allocate(bytes.length);

bb.put(bytes);

bb.flip();

CharBuffer cb = cs.decode(bb);

return cb.array();

}

char 转 byte[] 数组

public static byte[] charToByte(char c) {

byte[] b = new byte[2];

b[0] = (byte) ((c & 0xFF00) >> 8);

b[1] = (byte) (c & 0xFF);

return b;

}

byte[] 数组转 char

public static char byteToChar(byte[] b) {

char c = (char) (((b[0] & 0xFF) << 8) | (b[1] & 0xFF));

return c;

}
