你这断章取义的,谁知到在干什么
代码不完整,看不出这JB代码到底想干嘛。
爱干嘛干嘛,接分!
得了,结账吧
完全看不懂!

真是遇见高手了。求解释这代码太短了,好像是二维码
这代码太短了,好像是二维码
为什么eat12,14的情况。 不懂二维码的原理,看代码能看懂么?
Numeric mode 数字编码,从0到9。如果需要编码的数字的个数不是3的倍数,那么,最后剩下的1或2位数会被转成4或7bits,则其它的每3位数字会被编成 10,12,14bits 对应你的 estimateBitsModeNum
不同version下编码的位数:
对应你的 lengthIndicator

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
