Using BufferedReader to read Text File

Question

I'm having problems with using the BufferedReader

I want to print the 6 lines of a text file:

public class Reader {  public static void main(String[]args) throws IOException{      FileReader in = new FileReader("C:/test.txt");     BufferedReader br = new BufferedReader(in);      while (br.readLine() != null) {         System.out.println(br.readLine());     }     in.close();  } 

Now from what I can gather every time I call the readLine() method it automatically advances to the next line.

So I can't use the condition br.readLine() != null since it'll already advance it one line and I get the output:

Line 2 Line 4 Line 6 

What Condition do I use to check if there is still a new line in the text field.

Thanks in advance!

Answer 1

This is the problem:

while (br.readLine() != null) {     System.out.println(br.readLine()); } 

You've got two calls to readLine - the first only checks that there's a line (but reads it and throws it away) and the second reads the next line. You want:

String line; while ((line = br.readLine()) != null) {     System.out.println(line); } 

Now we're only calling readLine() once per loop iteration, and using the line that we've read both for the "have we finished?" and "print out the line" parts.
