当 int 类型左移/右移位数大于等于 32 位操作时，会先求余（%）后再进行左移/右移操作。也就是说左移/右移 32 位相当于不进行移位操作（32%32=0），左移/右移 42 位相当于左移/右移 10 位（42%32=10）。当 long 类型进行左移/右移操作时，由于 long 对应的二进制是 64 位，因此求余操作的基数也变成了 64。

也就是说：`x<<42`等同于`x<<10`，`x>>42`等同于`x>>10`，``x >>>42`等同于`i4 >>> 10`。
也就是说：`x<<42`等同于`x<<10`，`x>>42`等同于`x>>10`，`x >>>42`等同于`x >>> 10`。
