英文:
How to change a variable in a Class with dot notation?
问题
class MyClass(me: String) {
var name: String = "My Name"
}
为什么无法执行以下操作：
MyClass.name = "New Name"
我想要在主类中更改变量的值，而不想创建一个实例来执行此操作。在Kotlin中是否可能？
创建实例并更改该值显然不会更改主类的值，所以我主要寻找一种使用点符号来从主类中更改变量的方法，
这是否可能？
英文:
class MyClass(me : String) {
var name :String = "My Name"
}
Why can't i do
MyClass.name = "New Name"
I want to change the variable value in the main class, And i don't want to create an instance to do this. Is it possible in kotlin?
Creating instance and changing that value obviously doesn't change the value of main class, So i am mainly looking for a way to change the variable from the main class using the dot notation ,
Is it possible?

当然，要实现这个，只需将您的变量放入一个伴随对象，如下所示：
class MyClass(me: String) {
companion object {
var name = "我的名字"
}
}
在您当前的实现中，name 是一个实例属性，但显然您希望它是您的类的静态属性。
英文:
Sure, to accomplish this just put your variable into a companion object like this:
class MyClass(me : String) {
companion object {
var name = "My Name"
}
}
In your current implementation, name is an instance property, but you clearly want it to be a static property of your class.
