surround with try with resources

Here's an example of how to surround a code block with try-with-resources in Java:

try (FileInputStream fileInputStream = new FileInputStream("input.txt");
     BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(fileInputStream))) {
    // Code block to read and process the file
    String line;
    while ((line = bufferedReader.readLine()) != null) {
        // Process the line
    }
} catch (IOException e) {
    // Handle the exception
}

In this example, we're reading a file using a FileInputStream and wrapping it with a BufferedReader to read the file line by line. We're using try-with-resources to automatically close the resources (the FileInputStream and the BufferedReader) when we're done with them. If an IOException is thrown while reading the file, we're catching it and handling it appropriately.
