Problem reading a file

[R Dom]

I am reading text file in java using following code

BufferedReader bufferedReader = null;
		
		try {
			FileReader fileReader = new FileReader(filePath);
			//FileInputStream fis = new FileInputStream(new File(filePath));
			bufferedReader = new BufferedReader(fileReader);
			String line = null ;
			while((line = bufferedReader.readLine())!= null){
				
					System.out.println(line);
			
					 
				
				
			}
			fileReader.close();
			bufferedReader.close();
		} catch (Exception e) {
			e.printStackTrace();
		}

When i execute the code i am getting output as blank text in first line and then all the file details.

file details are :
6
123
3456

output:
blank line
6
123
3456

Anyone can help me with this? I am doing anything wrong in code?

[Seetharaman Venkatasamy]

your program looks ok for me. your input file has any blank line?

[R Dom]

no it doesnt have any blank line.

[Carey Brown]

Try replacing line 10 with
System.out.println( "'" + line + "'" ); // double-quote quote double-quote

Do you think that will make any difference? What about a test using the String methods before printing?

hi R Dom,

Could you post the entire code.....?
Might be you are printing some blank space.........

If the blank line does not now equal two single quotes then the blank line comes from somewhere else.

[Campbell Ritchie]

I missed the single quotes. Sorry. That is what comes from using 3mm tall writing on my screen.

Here is my full code

import java.io.BufferedInputStream;
import java.io.BufferedReader;
import java.io.DataInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.InputStreamReader;


public class InputFileReader {

	private String filePath;
	
	
	private void readFile(){
		BufferedReader bufferedReader = null;
		
		try {
			FileInputStream fis = new FileInputStream(filePath);
			DataInputStream dis = new DataInputStream(fis);
			bufferedReader = new BufferedReader(new InputStreamReader(dis));
			String line = null ;
			while((line = bufferedReader.readLine()) != null){
				System.out.println("'"+line+"'");
			}
		
	          bufferedReader.close();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
	
	public String getFilePath() {
		return filePath;
	}

	public void setFilePath(String filePath) {
		this.filePath = filePath;
	}

	public static void main(String [] args){
	
		InputFileReader reader = new InputFileReader();
		reader.setFilePath("D:\\input.txt");
		reader.readFile();
		
	}
}

Here is my output from code above:

''
'6'
'2, 3, 5'
'1, 3, 5'
'4'
'1, 3'
'4, 6'
'1, 5'
'p'
'q'
''
'p, q'
'p'

Input file is as follows:
6
2, 3, 5
1, 3, 5
4
1, 3
4, 6
1, 5
p
q

p, q
p

Hey Dom,

Your code works fine for me..
i get the output as that of the file.
your output is obtained only when there is a space in the file. You could check comparing the output with space.

Please try out with some other files to read...... and i feel its the error is with the file you read.

[R Dom]

I dont know why it doesnt work for me.. I dont have any spaces in input file.. I cant attach my txt file..anybody knows how can i attache my input file? this forum doesnt allow me to attach txt files.

your code work properly in my netbean.... Could you tell me what IDE are you using and what's your OS? Have you try run your code in a virtual machine in your PC?

I am using Eclipse Helios on Windows 7...
Does it matter? Java is suppose to be platform independent.

I know java is suppose to be platform independent. i just want to know your IDE and OS, it doesn't matter
