Can I use try-with-resources in legacy code?

Can I use try-with-resources in my legacy Java code?

Yes, you can use try-with-resources in legacy Java code, but it requires Java 7 or later.

What if my legacy code is written in Java 6?

If your code is in Java 6, you won't be able to use try-with-resources directly. You would need to refactor it to Java 7.

What are the benefits of using try-with-resources?

The main benefits are automatic resource management and reduced boilerplate code for closing resources.

Can you give me an example of how to implement it?

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);
    }
}
