Read data from a file using BufferedReader !!

Using BufferedReader:

1. import java.io.File;
2. import java.io.FileReader;
3. import java.io.BufferedReader;
4. 
   
5. public class ReadFileByBufferedReader {
6. 
   
7. public static void main(String[] args) {
8. try {
9. File file = new File("D://data.txt");
10. FileReader fr = new FileReader(file);
11. BufferedReader br = new BufferedReader(fr);
12. String line = br.readLine(); // read the line
13. while (null != line) {
14. System.out.println(line); // print the line
15. line = br.readLine(); // read the next line
16. }
17. fr.close();
18. } catch (Exception e) {
19. System.out.println("excepton occured in " + e);
20. }
21. }
22. }

Note: extension support .java/.txt/.xml/.yml/.html/.css etc file

Hi guys !!
This is Ishaan from India.
and I'm reading the data from a text file line by line using BufferedReader.
Isn't it interesting !! to read the data from a file line by line
irrespective of amount of data that a file is having.

II Approach:

1. import java.io.File;
2. import java.io.FileReader;
3. import java.io.BufferedReader;
4. 
   
5. public class ReadFileByBufferedReader {
6. 
   
7. public static void main(String[] args) {
8. File file = null;
9. FileReader fr = null;
10. BufferedReader br = null;
11. try {
12. file = new File("D://data.txt");
13. fr = new FileReader(file);
14. br = new BufferedReader(fr);
15. String line = br.readLine(); // read the next line
16. 
    
17. while (line != null) {
18. System.out.println(line); // print the line
19. line = br.readLine(); // read the next line
20. }
21. } catch (Exception e) {
22. System.out.println("excepton occured in " + e);
23. } finally {
24. try {
25. if (fr != null) {
26. fr.close();
27. }
28. if (br != null) {
29. br.close();
30. }
31. } catch (Exception e) {
32. System.out.println("excepton occured in finally block " + e);
33. }
34. }
35. }
36. // support .java/.txt/.xml/.yml/.html/.css etc file
37. }
