How does the try-with-resources statement work in Java?

How does the try-with-resources statement work in Java?

The try-with-resources statement in Java is used to automatically close resources like files or sockets. It ensures that each resource is closed at the end of the statement, which helps prevent resource leaks.

Can you give me an example of using 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 example, the BufferedReader is automatically closed after the try block.

What happens if an exception occurs inside the try block?

If an exception occurs inside the try block, it will be caught by the catch block, allowing you to handle the error gracefully. The resources declared in the try-with-resources statement will still be closed automatically.

Is try-with-resources available in C++ too?

No, try-with-resources is a feature specific to Java. However, C++ has similar functionality using RAII (Resource Acquisition Is Initialization) to manage resource lifetimes.
