Byte数组和Int的互相转换

public static int bytesToInt(byte[] bytes) {
    int addr = bytes[0] & 0xFF;
    addr |= ((bytes[1] << 8) & 0xFF00);
    addr |= ((bytes[2] << 16) & 0xFF0000);
    addr |= ((bytes[3] << 25) & 0xFF000000);
    return addr;

}

/* Int转byte[] */
public static byte[] intToByte(int i) {
    byte[] abyte0 = new byte[4];
    abyte0[0] = (byte) (0xff & i);
    abyte0[1] = (byte) ((0xff00 & i) >> 8);
    abyte0[2] = (byte) ((0xff0000 & i) >> 16);
    abyte0[3] = (byte) ((0xff000000 & i) >> 24);
    return abyte0;
