- Q1. Why is multiple inheritance not applicable in java
- Ans.
Java does not support multiple inheritance to avoid the diamond problem and maintain simplicity.
Java supports single inheritance to avoid ambiguity and complexity.
Multiple inheritance can lead to the diamond problem where a class inherits from two classes that have a common ancestor.
To resolve the diamond problem, Java uses interfaces which allow multiple inheritance of behavior but not state.
