Automatic Resource Management

Snippet

Automatic Resource Management

The try-with-resources statement ensures that each resource is closed at the end of the statement, preventing memory leaks and resource exhaustion.

snippet.java
java
import java.io.*;
 
public class TryWithResources {
    public static void main(String[] args) {
        try (BufferedReader br = new BufferedReader(new FileReader("test.txt"))) {
            System.out.println(br.readLine());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
