Why we can’t extend more than one class in java?
We can’t extend more than one class in Java. This is so, as Java does not support multiple inheritance because of ambiguity.
Consider the above diagram which shows multiple inheritance as Class D extends both Class B & C. Now lets assume we have a method in Class A and Class B & Class C overrides that method in their own way.

Henceforth, extension of multiple classes is restricted.
