Q2. What is supervised machine learning?
Ans. 
Supervised machine learning is a type of machine learning where the model is trained on labeled data.
• In supervised learning, the algorithm learns from labeled training data.

• Interfaces are used for achieving multiple inheritance in Java.

• Abstract classes can have instance v...read more
