Access Public Global Variables in class

[spatel14]

I wrote a class Ex1 that has a public double variable. It's global, therefore it's defined outside of any method. Now, can I get access to this variable in another class, called Ex2? If so, what is the syntax to do this?

[PhHein]

Ex1 x1 = new Ex1();
x1.doubleMember = 2d;

If doubleMember is an instance variable.

It's global

What does that mean? I'm not familiar with the global keyword.

Quite.
There isn't really such a thing in Java.
The closest is a "public static" attribute.

[clydedoris]

when he says global, he refers to a class variable..

[Tolls]

Except they don't say it's a class variable, because they don't say it's static. They merely say "it's defined outside of any method", and it's public. Which to me implies it's a member attribute, not a static class attribute.
