Exception Handling

Analogy: safety

Exceptions are like Bombs ticking in your code.

If you ignore them, your program CRASHES (Explodes).
If you use try-catch, you are the Bomb Squad. You diffuse the bomb safely and the program continues.

The Bomb Squad

You have 10 seconds to cut the correct wire.

Without Safety: Cutting the wrong wire crashes the system.
With try-catch: The safety net catches the explosion.

Bomb Squad (Exception Handling)

Safety Mode

Disabled: Cutting a wrong wire will CRASH the program (Explode).

00:10

The Code

Wrap dangerous code in a try block.

Java Example

Switch language in Navbar

try {
    cutWire(wire); // Might throw ExplosionException!
} catch (ExplosionException e) {
    System.out.println("Caught the explosion! We are safe.");
} finally {
    System.out.println("This runs no matter what.");
}
