十六进制文本如下，便于后续分析使用： CA FE BA BE 00 00 00 34 00 18 0A 00 04 00 14 09 00 03 00 15 07 00 16 07 00 17 01 00 01 61 01 00 01 49 01 00 06 3C 69 6E 69 74 3E 01 00 03 28 29 56 01 00 04 43 6F 64 65 01 00 0F 4C 69 6E 65 4E 75 6D 62 65 72 54 61 62 6C 65 01 00 12 4C 6F 63 61 6C 56 61 72 69 61 62 6C 65 54 61 62 6C 65 01 00 04 74 68 69 73 01 00 1F 4C 63 6F 6D 2F 64 73 6B 6A 2F 6A 76 6D 2F 62 79 74 65 63 6F 64 65 2F 4D 79 54 65 73 74 31 3B 01 00 04 67 65 74 41 01 00 03 28 29 49 01 00 04 73 65 74 41 01 00 04 28 49 29 56 01 00 0A 53 6F 75 72 63 65 46 69 6C 65 01 00 0C 4D 79 54 65 73 74 31 2E 6A 61 76 61 0C 00 07 00 08 0C 00 05 00 06 01 00 1D 63 6F 6D 2F 64 73 6B 6A 2F 6A 76 6D 2F 62 79 74 65 63 6F 64 65 2F 4D 79 54 65 73 74 31 01 00 10 6A 61 76 61 2F 6C 61 6E 67 2F 4F 62 6A 65 63 74 00 21 00 03 00 04 00 00 00 01 00 02 00 05 00 06 00 00 00 03 00 01 00 07 00 08 00 01 00 09 00 00 00 38 00 02 00 01 00 00 00 0A 2A B7 00 01 2A 04 B5 00 02 B1 00 00 00 02 00 0A 00 00 00 0A 00 02 00 00 00 06 00 04 00 08 00 0B 00 00 00 0C 00 01 00 00 00 0A 00 0C 00 0D 00 00 00 01 00 0E 00 0F 00 01 00 09 00 00 00 2F 00 01 00 01 00 00 00 05 2A B4 00 02 AC 00 00 00 02 00 0A 00 00 00 06 00 01 00 00 00 0B 00 0B 00 00 00 0C 00 01 00 00 00 05 00 0C 00 0D 00 00 00 01 00 10 00 11 00 01 00 09 00 00 00 3E 00 02 00 02 00 00 00 06 2A 1B B5 00 02 B1 00 00 00 02 00 0A 00 00 00 0A 00 02 00 00 00 0F 00 05 00 10 00 0B 00 00 00 16 00 02 00 00 00 06 00 0C 00 0D 00 00 00 00 00 06 00 05 00 06 00 01 00 01 00 12 00 00 00 02 00 13 Java字节码结构分析
