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

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

Sure! The try-with-resources statement is a feature in Java that simplifies resource management. It automatically closes resources like files or database connections when they are no longer needed.

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

In the traditional approach, you have to manually close resources in the finally block. With try-with-resources, the closing is handled automatically, reducing boilerplate code and the risk of resource leaks.

Can you provide a code example?

Certainly! 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 happens if an exception occurs while closing the resource?

If an exception occurs while closing the resource, it is suppressed and can be retrieved later using the getSuppressed() method. This allows you to handle multiple exceptions gracefully.
