What is the difference between try-with-resources and finally in Java?

What is the difference between try-with-resources and finally in Java?

Try-with-resources is a feature that automatically closes resources when done, while finally is used for cleanup.

Can you give me an example of try-with-resources?

Sure! Here's a simple example:

try (BufferedReader br = new BufferedReader(new FileReader("file.txt"))) {
    String line;
    while ((line = br.readLine()) != null) {
        System.out.println(line);
    }
} catch (IOException e) {
    e.printStackTrace();
}

In this case, the BufferedReader is automatically closed.

What happens if an exception occurs in try-with-resources?

If an exception occurs, it will be caught in the catch block, and the resources will still be closed automatically.

Is finally still necessary if I use try-with-resources?

Not usually, since try-with-resources handles resource closure. However, finally can still be used for other cleanup tasks.
