Multiple inheritance

Multiple inheritance is a term from object oriented programming. In every modern object oriented programming language, a class can inherit from another class. Multiple inheritance simply means that a class can inherit from more than one class. An example of a programming language where this is possible is C++. In Java, it is not possible, but in most situations one can use interfaces instead to get the same thing in a different way. More specifically, in Java a class can inherit from only one class, but can ''implement'' multiple interfaces.

Example in C++:

class A
{
public:
  int GetA() { return a; }
  void SetA(int n) { a = n; }
private:
  int a;
};
class B
{
public:
  int GetB() { return b; }
  void SetB(int n) { b = n; }
private:
  int b;
};
class C: public A, public B
{
public:
  int GetSum() { return GetA()+GetB(); }
};
int main()
{
  C c;
  c.SetA(5);
  c.SetB(7);
  cout << c.GetSum() << endl; // is 12
}
