Java doesnt support multiple inheritance but it provide a way through which it can enact it.
Consider the scenario is C++
Class A{
public void add(){
// some text
}
}
Class B{
public void add(){
// some text
}
}
Class C extends A,B{
public static void main(String arg[]){
C objC = new C();
objC.add(); // problem, compiler gets confused and cant
decide to call Class A or B method.
}
This problem is called Diamond problem.
This problem in java is taken care with the use of interfaces
In Java similar problem would look like:
interface A{
add();
}
interface B{
add();
}
class C implements A,B{
add(){
// doesnt matter which interface it belong to
}
}
