How do i remove this last line

[steady junco]

Hello, I have pretty much completed this assignment and coded everything right, just for the completion it cant end on a new empty line and I can not figure out how to not have it.

My code:
import java.io.FileNotFoundException;
import java.io.File;
import java.io.PrintWriter;
import java.util.Scanner;

public class FunWithFiles {

/**
* Displays the file given by fname to the screen
*
* @param fname file to be displayed
*/
public static void displayFile(String fileName) {
try {
File bFile = new File(fileName);
Scanner fscnr = new Scanner(bFile);
while(fscnr.hasNextLine()) {
if(fscnr.hasNextLine()) {
System.out.println(fscnr.nextLine());
}
}
fscnr.close();
} catch (FileNotFoundException e) {
System.out.println("ERROR - File " + fileName + " not found!");

    }

}

public static void main(String[] args) {
  Scanner scnr = new Scanner(System.in);
  System.out.print("Enter a filename: ");
  String fileName = scnr.nextLine();
  displayFile(fileName);

  scnr.close();
}

}

While you are waiting for getting help, here are some tips to improve your experience:

Code is much easier to read if posted with syntax highlighting and proper formatting.

If nobody is calling back, that usually means that your question was not well asked and hence nobody feels confident enough answering. Try to use your time to elaborate, provide details, context, more code, examples and maybe some screenshots. With enough info, someone knows the answer for sure.

Don't forget to close your thread using the command </help-thread close:1027500463647621170> when your question has been answered, thanks.

hey there!

i don't get what is your problem exactly

would you like to give us a friendly description about your question or issue please ?

[steady junco]

When the code is ran it outputs a empty line at the end of it and I need it to not output that extra line

so like in this image my output is the first part but I need it to look like the second part and the only thing that is off is that its outputting an extra line and I can not figure out how to get it to not do that

[fleet swan]

ah i get it

first of all your code is ugly

second, you dnt need that if inside the while ()

maybe that check is making the issue

[steady junco]

Oh i know i dont need that If, i was trying to fix the problem with that lol

ill send updated code

[fleet swan]

try to do

try {
    File bFile = new File(fileName);

    Scanner fscnr = new Scanner(bFile);

    while (fscnr.hasNextLine()) {
        System.out.println(fscnr.nextLine());
    }

    fscnr.close();

} catch (FileNotFoundException e) {
    System.out.println("ERROR - File " + fileName + " not found!");
}

[steady junco]

Yeah i got that

[fleet swan]

fixed ?

[steady junco]

No its still doing it

[fleet swan]

did you save the file before recompiling ?

[steady junco]

Yes

[fleet swan]

alright, in that case

try to check if the line is NOT empty

[mint stream]

..

println prints a newline character at the end

that includes the last line as well

[steady junco]

So how would I do it without println?

[fleet swan]

while (fscnr.hasNextLine()) {
  String line = fscnr.nextLine();
  if(!line.empty){
    println()
  }
}

[mint stream]

uh no

that's not the issue @fleet swan

the last line isn't empty

it has text, but println prints a newline character after it

So basically, you gotta somehow use println for every line except the last

[steady junco]

Yeah

[fleet swan]

hmm in that case, maybe he should switch to for

but i didn't use it with scanner

[mint stream]

you could use a for loop and check for the last

uhh looking for other options rq

[steady junco]

thank you guys 😅

[mint stream]

oh a simpler option is using hasNextLine again

if you use hasNextLine after the nextLine statement, you will know if the loop will run again

hasNextLine will be false if this was the last iteration, since that's the condition of the while loop

so- use println if hasNextLine is true, and use print if it's false

[steady junco]

Okay ill try it

thank you

[mint stream]

From to this stackoverflow answer

[steady junco]

It worked thank you!

[mint stream]

🎉

Have fun coding ^-^
