nsigned byteがJavaにないことを知っています。では、から255(16進数)までの整数を使用してバイト配列を初期化するにはどうすればよいですか?
final byte assoc_resp_msg_int[] = new byte[] {
0xe3, 0x00, //APDU CHOICE Type(AareApdu)
0x00, 0x2c, //CHOICE.length = 44
0x00, 0x00, //result=accept
0x50, 0x79, //data-proto-id = 20601
0x00, 0x26, //data-proto-info length = 38
0x80, 0x00, 0x00, 0x00, //protocolVersion
0x80, 0x00, //encoding rules = MDER
0x80, 0x00, 0x00, 0x00, //nomenclatureVersion
0x00, 0x00, 0x00, 0x00, //functionalUnits, normal Association
0x80, 0x00, 0x00, 0x00, //systemType = sys-type-manager
0x00, 0x08, //system-id length = 8 and value (manufacturer- and device- specific)
0x88, 0x77, 0x66, 0x55, 0x44, 0x33, 0x22, 0x11,
0x00, 0x00, //Manager's response to config-id is always 0
0x00, 0x00, //Manager's response to data-req-mode-flags is always 0
0x00, 0x00, //data-req-init-agent-count and data-req-init-manager-count are always 0
0x00, 0x00, 0x00, 0x00, //optionList.count = 0 | optionList.length = 0
};
0x80
を次のようにバイトに格納する必要があります:
final byte assoc_resp_msg_int[] = new byte[] {
(byte)0xe3, 0x00, //APDU CHOICE Type(AareApdu)
0x00, 0x2c, //CHOICE.length = 44
0x00, 0x00, //result=accept
0x50, 0x79, //data-proto-id = 20601
0x00, 0x26,
(byte)0x80,
...
}
System.out.println(assoc_resp_msg_int[10]&0xFF);
//128
