Now I have 3 questions out of this code-::
1) why my
java compiler is not permitting me to write implements before extends?
2) I have not given definition of disp() method of my interface but implemented the same method in class Cls as public method..It is giving compile time error like disp was not defined in ClsMain.Even though its definition has to be found as it is inherited from Cls by ClsMain?
3) Is it an example of multiple inheritance by classes in java?
