Hi,
One simple scenario for you to understand this. Say you wanted to keep track
of the number of instances created from a particular class.
public class MyClass {
static int count = 0;
public MyClass() {
count++;
}
//...................
}
So using this "MyClass.count" anyone can check the number of instances
created inside a program.
Just a simple example.
Cheers,
Kamal
