Java question

[Trippyginger]

I am learning java and I was wondering if there is a way to have a variable that can be called upon in two separate classes. In most cases you can call upon the variable that you declared in a specific class and you can use it throughout the class. But is there a way to use that same variable though more than one class?

Yes, you need a reference to the object that is "holding" the variable and you need to make the variable public or create a getter/setter.

1. Declare the variable as static and access it as ClassName.VariableName in any other class.

 

Keep Access control/Thread safety in mind if you plan on modifying the value.

I'm not sure if I understand the question correctly, but I can think of two ways to do this.

 

1. Create a class to hold that variable and create an instance of that class and manipulate it with other classes.

 

2. Make the variable static in a class and call upon the class to access the variable.

 

There are pros and cons to both and there are probably other ways to do this also.
