问题描述
我最近开始使用Eclipse IDE,并在许多地方阅读,不应该使用默认(src)包并创建新的包。我只想知道这个原因
使用默认包可能会创建命名空间冲突。假设您正在创建一个包含 MyClass
类的库。有人在他的项目中使用你的库,并且在他的默认包中也有一个 MyClass
类。编译器应该做什么? Java中的包实际上是一个完全标识您的项目的命名空间。所以重要的是不要在现实世界的项目中使用默认包。
I recently started using Eclipse IDE and have read at a number of places that one shouldn't use the default(src) package and create new packages.
I just wanted to know the reason behind this.
Using the default package may create namespace collisions. Imagine you're creating a library which contains a MyClass
class. Someone uses your library in his project and also has a MyClass
class in his default package. What should the compiler do? Package in Java is actually a namespace which fully identifies your project. So it's important to not use the default package in the real world projects.
这篇关于为什么我们不应该使用(默认)src包?的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
