Problem Explanation

Explanation

To solve this problem, we need to read the text file line by line and output the 10th line. We can achieve this by using a simple loop to read each line until we reach the 10th line. If the file contains less than 10 lines, we can output nothing.

Solution Code

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

public class TenthLine {
    public static void main(String[] args) {
        try {
            BufferedReader br = new BufferedReader(new FileReader("file.txt"));
            String line;
            int count = 0;
            while ((line = br.readLine()) != null) {
                count++;
                if (count == 10) {
                    System.out.println(line);
                    break;
                }
            }
            br.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
