interface | 易学教程

接触了go语言已经有几个月的时间了，虽然大部分的系统包还不是很熟练，但是对于go也算是有一定的了解。go语言在语言的层面上并没有非常亮眼的地方。在效率方面,go语言不及c/c++，在移植性上go语言不及java，在高并发方面erlang也能做的很好。所以go会给人有一种很全能的感觉，在各个方面都做了适当的取舍。在开发效率上go会比较快些。 go语言中，interface是重点。在面向对象设计中，有组合优于继承这句话。go语言放弃了继承，在组合方面表现的很好。首先来看看interface的用法。interface有两种用法：１，空接口，用过C/C++的人看了空接口的定义第一时间想到的就是C/C+＋中的void*。 var Businesser interface{} var IntData int = 100 var StringData string = "i love hxc" Businesser = IntData var IntData2 int = Businesser.(int) fmt.Println(Businesser) // 100 fmt.Println(IntData2) //100 Businesser = StringData var StringData2 string = Businesser.(string) fmt.Println
