In the case a Java, if a variable at the class level (called a "field" in Java) is declared as static, a single copy of such a variable exists, no matter how many objects are created for the class. This lets you share information between different objects; you can also access such a variable without creating a single object, using the class name. A good example are the fields Math.PI and Math.E, i.e., fields in the "Math" class which you can access without creating an object based on the class.
