老实说笔者学习 Go 的时间并不长,积淀也不深厚,这次因缘巧合,同组的同事以前是上海大学的开源社区推动者之一,同时我们也抱着部分宣传公司和技术分享的意图,更进一步的,也是对所学做一个总结,所以拟定了这次分享.另外与会的同学大多都是大二大三的"萌新",考虑到受众水平和技术分享的性质,所以实际上这次分享涉及到的知识点都相对基础,当然为了寓教于乐,本人也十分讨厌着重介绍基础语法时可能引起的枯燥,所以加了少少的私货,并且也针对 1.11 及之前版本中或优雅,或局限的特性做了发散性的讲解. 总而…

Static and non-Static :  非静态方法(不带static)可以访问静态变量和方法(带static),但是反过来就不行. 类的静态成员(变量和方法)属于类本身,在类加载的时候就会分配内存,可以通过类名直接去访问. 非静态成员(变量和方法)属于类的对象,只有在类的对象产生(创建实例)的时候才会分配内存,然后通过类的对象去访问. 在一个类的静态成员中去访问非静态成员之所以会出错是因为在类的非静态成员不存在的时候静态成员就已经存在了,访问一个内存中不存在的东西会出错. 静态变量和方…
