使用静态修饰符声明一个静态成员，属于键入本身而不是特定的对象.

Use the static modifier to declare a static member, which belongs to the type itself rather than to a specific object.

???

当我定义一个变量 public int abc 时，我遇到了这个静态关键字.当这个变量的值在while的括号内，或if的括号内，或方法的括号内发生变化时，这些变化是无效的，没有反映, 括号外不知道.所以只是一个命中试验.我将变量设为静态并解决了所有问题.

My encounter with this static keyword occurred when I defined a variable public int abc. When the value of this variable changed withing the brackets of while, or within the brackets of if, or within the brackets of methods, these changes were not valid, were not reflected, were not know outside the brackets. So just a hit trial. I made the variable static and all problems solved.

但是为什么??

推荐答案

静态成员和非静态成员(不是变量)的区别在于，静态成员在程序的整个运行时是唯一的(即有只有一个静态成员实例)，而非静态成员与对象实例相关联(即，对应对象的每个实例都有一个成员实例).这是定义所说的多一点.

The difference between a static and a non-static member (not variable) is that a static member is unique over the whole runtime of a program (i.e. there is only one static member instance) whereas a non-static member is associated with an object instance (i.e. there is a member instance for each instance of the corresponding object). This is in a bit more words what the definition says.

这一切如何适用于您所写的未反映的更改，我不太确定 - 也许您应该发布相应的代码.

How this all applies to what you wrote in regard to changes not reflected im not too sure - maybe you should post the corresponding code.
