Static methods do not use any instance variables of any object of the class they are defined in. Static methods take all the data from parameters and compute something from those parameters, with no reference to variables. We can inherit static methods in Java.
Quick A: Yes, and there are no ambiguity with static members.
The static variables can be accessed in the static methods only if we try to access the non-static variables in the static method compiler will show an error because non-static variables can only access by creating an instance of the class only but static methods can be called without creating an instance of the class ...
A static variable shares the value with every object of the class that declares it. So every subclass will have that value too. If the main class or other subclass change that value, every class (no matter if parent or subclass) will have the new value.
I have these C++ classes:
class Base
{
protected:
static int method()
{
static int x = 0;
return x++;
}
};
class A : public Base
{
};
class B : public Base
{
};
Will the x static variable be shared among A and B, or will each one of them have it's own independent x variable (which is what I want)?
