问题描述
我是Java编程的新手。任何人都能说出Java中全局变量和局部变量之间的区别吗?
I am new to Java programming. Can anyone tell what is the difference between global and local variable in Java?
推荐答案
你提到的问题有点困惑标题中的static / global,以及问题中的global / local。
Your question is a little confused since you refer to static/global in the title, and global/local in your question.
static
变量绑定到 class ,每个类你将有一个实例。
static
variables are tied to a class, and you will have one instance per class.
类可以有成员变量,你将拥有该类的每个实例一个实例。
classes can have member variables, and you will have one instance per instance of that class.
请注意,如果您有多个类加载器,这会更复杂。在这种情况下,您可以加载多个类定义,因此可能有多个静态变量。
Note that this is complicated further if you have multiple classloaders. In this scenario you can have multiple class definitions loaded, and consequently, possible multiple static variables.
