In this article, we would like to show you how to use try with resources in Java.

Below we present a comparison of two solutions:

try-with-resources,
try with finally block.

1. Using try-with-resources

Edit

xxxxxxxxxx
 
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
​
public class Example {
​
    public static void main(String[] args) {
        String path = "C:\\path\\example.txt";
​
        try (BufferedReader br = new BufferedReader(new FileReader(path))) {
            System.out.println(br.readLine());
​
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

2. Using `try` with `finally` block instead

Edit

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
​
public class Example {
​
    public static void main(String[] args) throws IOException {
        String path = "C:\\path\\example.txt";
​
        BufferedReader br = new BufferedReader(new FileReader(path));
        try {
            System.out.println(br.readLine());
​
        } finally {
            br.close();
        }
    }
}
