Section 6.6 Static member variables
Suppose that you wanted to write a Student class so that the class could keep track of the number of students it had created. Although you could do this with a global counter variable that is an ugly solution. The right way to do it is to use a
static variable. In Python, we could do this as follows:
In Java, we would write this same example using a
static declaration.
In this example notice that we create a static member variable by using the
static modifier on the variable declaration. Once a variable has been declared static in Java it can be accessed from inside the class without prefixing the name of the class as we had to do in Python.
