When would I use a Static Object reference

Question

I have been coding in Java for sometime and I understand the difference between Static and non static methods. But I recently came across static Object reference

 private static Work workTwo = new Work();

What is the need for a static object reference and under what case should I include them in my code

Same as for a method: when you want it to belong to the class itself rather than an instance of it. — azurefrog, Feb 03 '17 at 18:45
`static final` constants for a class that may be used by all objects from that class — CraigR8806, Feb 03 '17 at 18:46

Use it when the semantics are what you need. Specifically when you want the value to exist only once and be shared across all instances of the class, or the entire application. static final is good for immutable constants (eg numbers or strings).
