Let’s explore 1 - try/catch Basics 🤖
Java lets you handle errors using try and catch. This keeps your robot from crashing when something unexpected happens.
Basic Structure
try {
// risky code goes here
} catch (Exception e) {
out.println("Oops! " + e.getMessage());
}Use try/catch when you read files, work with user input, or call methods that might throw exceptions.
When to Use
- Setup code – loading resources like images or sound
- Math operations – guarding against divide-by-zero errors
- API calls – catching network or parsing issues
Handling errors gracefully shows kindness to your future self and teammates.
