    }

-40, -62, 107, 66, -126,

-40, -62, 107, 66, 0x82,

看bytecode窗口是 -0x7e ，应该是-126啊。。。不知道怎么转了0x82了。

[Asm] 纯文本查看 复制代码

.array-data 1 x 0x78
              -0x28
              -0x3E
              0x6B
              0x42
              -0x7E
              0x67
              -0x38

差太多了。为什么这样？怎么解决？

-126的16进制，在编译器里就是0x82
