Solution

ReadTextFile.java

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

public class ReadTextFile {
    public static void main(String[] args) {
        // Path of the file you want to read
        String filePath = "file_path.txt";

        try {
            // Create a FileReader object to read the file
            FileReader file = new FileReader(filePath);

            // Create a BufferedReader object to read lines of text efficiently
            BufferedReader reader = new BufferedReader(file);

            // Read the first line of the file
            String line = reader.readLine();

            // Iterate over all lines of the file until you reach the end
            while (line != null) {
                // Display the line on the console
                System.out.println(line);

                // Read the next line
                line = reader.readLine();
            }

            // Close the BufferedReader and FileReader
            reader.close();
            file.close();

        } catch (IOException e) {
            // Handle possible input/output exceptions
            e.printStackTrace();
        }
    }
}

import java.io.BufferedReader; import java.io.FileReader; import java.io.IOException; public class ReadTextFile { public static void main(String[] args) { // Path of the file you want to read String filePath = "file_path.txt"; try { // Create a FileReader object to read the file FileReader file = new FileReader(filePath); // Create a BufferedReader object to read lines of text efficiently BufferedReader reader = new BufferedReader(file); // Read the first line of the file String line = reader.readLine(); // Iterate over all lines of the file until you reach the end while (line != null) { // Display the line on the console System.out.println(line); // Read the next line line = reader.readLine(); } // Close the BufferedReader and FileReader reader.close(); file.close(); } catch (IOException e) { // Handle possible input/output exceptions e.printStackTrace(); } } }
