Question: The following code snippet is used to read a file named "text.txt" and count the number of lines in the file. However, there is an error in the code. Identify and correct the error(s), and explain your solution.

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

public class FileReadingExample {
    public static void main(String[] args) {
        File file = new File("text.txt");
        try {
            Scanner scanner = new Scanner(file);
            int count = 0;
            
            while (scanner.hasNext()) {
                count++;
                scanner.nextLine();
            }
            
            System.out.println("Number of lines in the file: " + count);
        } catch (FileNotFoundException e) {
            System.out.println("File not found");
        }
    }
}

Answer: The error in the given code is that the scanner.nextLine() method is called after incrementing the count variable, resulting in an incorrect count of lines in the file.

To correct the error, the scanner.nextLine() method should be called before incrementing the count variable.

Modified code snippet:

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

public class FileReadingExample {
    public static void main(String[] args) {
        File file = new File("text.txt");
        try {
            Scanner scanner = new Scanner(file);
            int count = 0;
            
            while (scanner.hasNextLine()) {
                scanner.nextLine();  // Move this line before count++
                count++;
            }
            
            System.out.println("Number of lines in the file: " + count);
        } catch (FileNotFoundException e) {
            System.out.println("File not found");
        }
    }
}

Explanation: In the original code, the scanner.nextLine() method was called after incrementing the count variable. This means that the first line of the file was skipped before incrementing the count. As a result, the count was off by one.

By moving the scanner.nextLine() method before incrementing the count variable, the correct line is read from the file and then the count is incremented. This ensures that all lines are accounted for correctly.

Now, when executing the modified code, it will correctly count the number of lines in the file and print the result.
