Java Read From a Text File

In this article, we will read a text file and print out its content.

Example:

To represent the text file, create a File object.
To read the contents of the file, create a Scanner object.
Use the Scanner object to read the contents of the file line by line or character by character.
Close the Scanner object to free up its resources.

Here is the text file content.

package week1.day2;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.util.Scanner;
public class Calculator {
    public static void main(String[] args) throws IOException {
        // Create a File object to represent the text file
        File file = new File("C:\\Users\\arili\\git\\Assignments\\Selenium\\target\\OnePiece.txt");
        try {
            // Create a Scanner object to read the contents of the file
            Scanner scanner = new Scanner(file);
            // Use the Scanner object to read the contents of the file line by line
            while (scanner.hasNextLine()) {
                String line = scanner.nextLine();
                System.out.println(line);
            }
            // Close the Scanner object to release the resources used by it
            scanner.close();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
    }
}

In this example, the File object is created using the path of the text file.
The Scanner object is then used to read the contents of the file line by line using a while loop.
Each line is printed to the console using the println() method.
Finally, the Scanner object is closed using the close() method.
