Why is the program not displaying the lines with the strings one, two, etc?
Thanks

outputFile.println("four");
outputFile.println("five");

File file = new File(filename);
Scanner inputFile = new Scanner(file);

while (inputFile.hasNext())
{
String friendName = inputFile.nextLine();

System.out.println(filename);

inputFile.close();
















}
}

Can i see the output??

Do not understand what you are asking I am a complete novice

I've never used Scanner, but a quick glance at the API doc for the class makes me think that 'hasNext' and 'nextLine' is not a good combination. 'hasNext' and 'next' seem better matched but not appropriate for you, since you're not (yet) interested in delimiters. There's a more appropriate method than 'hasNext' to test for more lines of input. Try that one and see if you get what you want.

Put your code in code tags. See the "BB Code" link below.

There is no code to print those lines.
Can you copy the console contents here from when you execute the program?

On windows: To copy the contents of the command prompt window:
Click on Icon in upper left corner
Select Edit
Select 'Select All' - The selection will show
Click in upper left again
Select Edit and click 'Copy'

Paste here.

I expect to see the name of the file printed several times.

Im sorry I do not understand what you are suggesting besides BBCODE

Norm has done a better job than I have of reading your code :D

Yes I am getting that inside of NetBean IDE. I want it to print One two three etc.

Look at the name of the variable that you are reading the file's lines into
and compare it to the name of the variable that is being printed.

Think about what you see printed.

CHECK THE LINE WHERE I PUT ARROW HEAD

Code :

import java.io.*;
import java.util.Scanner; 
 
 
public class yourClass{
 
/**
* @param args the command line arguments
*/
public static void main(String[] args) throws IOException {
 
String filename;
 
 
 
//create keyboard
Scanner keyboard = new Scanner(System.in); 
 
 
//get filename
System.out.print("Please give filename: "); 
filename = keyboard.nextLine(); 
 
//open file
PrintWriter outputFile = new PrintWriter(filename); 
 
outputFile.println("one"); 
outputFile.println("two");
outputFile.println("three");
outputFile.println("four");
outputFile.println("five"); 
 
//close
outputFile.close();
 
File file = new File(filename); 
Scanner inputFile = new Scanner(file); 
while (inputFile.hasNext())
{
String friendName = inputFile.nextLine(); 
 
System.out.println(friendName);  //IT SHOULD BE friendName not filename. <<<<<<<<<---------------------------------
}
inputFile.close();	
}}

Please tell me if it is obvious because I have been at this since 9am this morning

Thanks. About to try right now.
