Q2. Why java doesn't support multiple inheritance?
Ans. 
Java doesn't support multiple inheritance to avoid the diamond problem.
• Multiple inheritance can lead to the diamond problem where a class inherits from two classes with a common parent.

• This can cause ambiguity in method calls and lead to code complexity.

• Java supports multiple interface inheritance to achieve similar functionality.

• For example, a class can implement multiple interfaces to inherit their methods.

• This allow...read more
