How do I handle checked exceptions in Java?

How do I handle checked exceptions in Java?

In Java, checked exceptions must be either caught or declared in the method signature. You can use try-catch blocks to handle them.

Can you give me an example of using try-catch for a checked exception?

Sure! Here's a simple example:

try {
    FileReader fr = new FileReader("file.txt");
} catch (FileNotFoundException e) {
    System.out.println("File not found: " + e.getMessage());
}

What happens if I don't handle a checked exception?

If you don't handle a checked exception, the compiler will throw an error, and your program won't compile.

Are there any best practices for handling checked exceptions?

Yes, it's best to handle exceptions at a level where you can take meaningful action, and avoid catching generic exceptions unless necessary.
