A method which is not abstract i.e. if a methods definition is given in the same class its declared is called concrete. where as abstract method would have no definition till the deep down of the hierarchy of class structure but ll ve a declaration in all the subclasses and definition in one subclass after which it need not be declared in the further subclasses. By the way defining the abstract method in a subclass would end the carrying of the declaration till down, but defining it is not mandatory where declaring is mandatory.

Why is multiple inheritance not provided in Java?
One of the main reasons for creating Java was to address the problems of C++. One such problem was multiple inheritance, which was prone to ambiguity when a class inherited from two separate classes which shared a function with an identical definition. The designers of Java decided to eliminate this problem altogether by only allowing a class to inherit from a single other concrete class.
