This is not a good practice, but if you really need it, there is a number of ways:

1. Web apps: You can put your variable in some kind of context, like the session or the application scope.
2. Desktop apps: You can create an object and store it as a property of a class that always have an object active.
3. Any kind of app: use a public static property. It is visible to everyone.
