What are some common exceptions in Java and Python?
In Java, common exceptions include NullPointerException, ArrayIndexOutOfBoundsException, and IOException. In Python, you often encounter ValueError, TypeError, and KeyError.
Can you explain what a NullPointerException is?
A NullPointerException in Java occurs when you try to use an object reference that has not been initialized, meaning it points to null.
How does a KeyError differ in Python?
A KeyError in Python happens when you try to access a dictionary key that does not exist, indicating that the key is not found.
Are there ways to handle these exceptions?
Yes, both Java and Python provide mechanisms like try-catch blocks in Java and try-except blocks in Python to handle exceptions gracefully.
