java - Maintaining global but changeable variables across classes/packages

Question

I want to maintain some global variables that can be changed in Java. And once the state/value of a variable changes, next time I use this variable I should have the new changed state/value.

For example I use a config property and once changed, the new value should be used thereafter.

I am not able to figure out how to achieve this in Java. Any suggestions would be very helpful.
