What are static objects in java?
There is no separate entity as a static object in java. The static keyword in java is used to signify that the member (either a variable or a method) is not associated to an object instance of the class. It signifies the fact that the member belongs to the class as a whole. The words static and objects are opposites of one another so you cannot have a static object. However, you can declare an object as a class level variable which could be referred to as a static object but it will be referred to as a static or class variable and not a static object.
