JAVAは2つのbyte配列を1つにまとめる

    /**
     *    byte       
     * @param data1        1
     * @param data2        2
     * @return        
     */
    public static byte[] mergeBytes(byte[] data1, byte[] data2) {
        byte[] data3 = new byte[data1.length + data2.length];
        System.arraycopy(data1, 0, data3, 0, data1.length);
        System.arraycopy(data2, 0, data3, data1.length, data2.length);
        return data3;
    }
