Instance variables are always associated with an instance of a class (an
object). Class variables are shared across all instances of a single class
(indicated by the static keyword in the variable declaration), modify its
value in instance A and instances B-Z also reflect the change.
For instance:
public class TestClass
{
private String instanceVariable = "A variable which is unique between
instances of this class";
private static String classVariable = "A variable shared between all
instances of this class.";
public TestClass()
{
// constructor
}
}
