What are the best practices for file I/O in Java?

Some best practices include using BufferedReader and BufferedWriter for efficiency, handling exceptions properly, and closing resources in a finally block.

Why is it important to close resources?

Closing resources like streams is crucial to prevent memory leaks and ensure that system resources are released properly.

Can you give an example of using BufferedReader?

Sure! Here's a simple example:

BufferedReader reader = new BufferedReader(new FileReader("file.txt"));
String line;
while ((line = reader.readLine()) != null) {
    System.out.println(line);
}
reader.close();

What about using try-with-resources?

Using try-with-resources is a great practice as it automatically closes resources. Here's how you can use it:

try (BufferedReader reader = new BufferedReader(new FileReader("file.txt"))) {
    String line;
    while ((line = reader.readLine()) != null) {
        System.out.println(line);
    }
}
