how can I read the data inside a .txt file which I have created in the data using online gdbcompiler in Java?

Question

my code :

import java.io.File;
import java.util.Scanner;

public class BacaFail{
public static void main(String []args) throws Exception{

        File f=new File("data.txt");
        Scanner sc=new Scanner(f);
        
        while(sc.hasNextLine()){
            System.out.println(sc.nextLine());
        }
    }
}

Answer 1

The file you create (data.txt) will be in your project listed alongside the source file. This way, you can manually look at it, just like at your code files.

Alternatively, you can access it just like in your example: from code.

Answer 2

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;

public class ReadFile {
    public static void main(String[] args) {
        // Change this to the name of your file
        File file = new File("data.txt");

        try (Scanner scanner = new Scanner(file)) {
            while (scanner.hasNextLine()) {
                String line = scanner.nextLine();
                System.out.println(line); // Print each line
            }
        } catch (FileNotFoundException e) {
            System.out.println("File not found: " + e.getMessage());
        } catch (Exception e) {
            System.out.println("An error occurred: " + e.getMessage());
        }
    }
}
