Reading a text file using FileReader & BufferedReader : Unexpected output !

[Rahul Sudip Bose]

the program below compiles properly. Its supposed to "print" the below source code saved inside "mytxt.txt" . But i get only some parts of the text in output.

import java.io.*;

class writing 
{
public static void main(String args[ ])
{
try
{
//make a 'file' object 
File file = new File("mytxt.txt");
//Get data from this file using a file reader. 
FileReader fr = new FileReader(file);
//To store the contents read via File Reader
BufferedReader br = new BufferedReader(fr);                                                 
//Read br and store a line in 'data', print data
String data;
while(br.readLine( ) != null) 
{
data = br.readLine( );   		 	                       
System.out.println(data);
}                                
}catch(IOException e){System.out.println("bad !")}

}      

}

PS : how do i upload the screen shot of the console output from my pc ?

You are reading from your file twice at each iteration, but you are only storing half of the lines in data.

I surmise that it is only printing the even numbered lines in your file. That is because your while statement is reading a line and then you read another line in the while loop. And you only print the line that was read in the loop. Try:

import java.io.*;

class writing 
{
    public static void main(String args[ ])
    {
        try {
            // make a 'file' object 
            File file = new File("mytxt.txt");
            //  Get data from this file using a file reader. 
            FileReader fr = new FileReader(file);
            // To store the contents read via File Reader
            BufferedReader br = new BufferedReader(fr);                                                 
            // Read br and store a line in 'data', print data
            String data;
            while((data = br.readLine()) != null) 
            {
                //data = br.readLine( );                                     
                System.out.println(data);
            }                                
        } catch(IOException e) {
            System.out.println("bad !");
        }
    }      
}
