In many languages, when faced with a problem like this, we can declare a global variable Java Constant. As the name suggests, a constant is an entity in programming that is immutable. In other words, the value that cannot be changed.

So, the state of the object can be changed but not the reference. With variables, the final modifier often is used with static to make the constant a class variable.
