What is the try-with-resources statement in Java?

Can you explain what the try-with-resources statement is in Java?

Sure! The try-with-resources statement is a feature in Java that simplifies resource management, ensuring that resources like files or database connections are closed automatically after use.

How does it differ from the traditional try-catch-finally approach?

In the traditional approach, you have to explicitly close resources in a finally block, which can lead to boilerplate code. Try-with-resources automatically closes resources, making the code cleaner and less error-prone.

Can you provide a code example?

Absolutely! 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 example, the BufferedReader is automatically closed after the try block.

What types of resources can be used with try-with-resources?

You can use any resource that implements the AutoCloseable interface, such as InputStream, OutputStream, and database connections.
