What are exceptions?

Imagine you're building a tower with blocks, and suddenly one block falls, that’s like an exception. It's when something goes wrong in a simple plan.

When you’re playing a game or doing a task, everything usually works smoothly. But sometimes, something unexpected happens, just like how your favorite toy might break if you drop it too hard. That surprise is what we call an exception.

What Exceptions Do

Think of a robot that’s supposed to count apples in a basket. It sees 5 apples and starts counting: 1, 2, 3, 4, 5. But then it tries to count one more apple, and there isn’t any! The robot gets confused. That confusion is an exception.

Sometimes, the robot can fix itself by saying, “Oh, there are no more apples,” and just stops counting. That’s like how a grown-up might say, “No worries, we’ll try again later.”

Exceptions help us understand when things don’t go as planned, like your tower of blocks falling down or your favorite toy breaking, so we can fix them or try something new.
