How to read the file name as a string variable after informing the reader the file name should end in the suffix .txt?

Hi I Posted a similar question yesterday, but now I need help with reading the file name as a string variable. Attached is my updated code 

import java.io.*;
import java.util.*;
public class SongWriter {

    public static void main(String[] args) {
        PrintWriter outputStream = null;

        // Scope must be outside the try/catch structure.
        String fileName1;
        Scanner keyboard = new Scanner(System.in);
        System.out.print("Enter the name of the file. The file should end in the suffix.txt ");
        fileName1 = keyboard.next();

        try {
            outputStream = new PrintWriter("Song.txt");
            // new FileOutputStream("Song.txt")
        } catch (FileNotFoundException e) {
            System.out.println("Error opening the file Song.txt.");
            System.exit(0);
        }

        System.out.println("\n classical songs has many lines");
        System.out.println("\nNow enter the three lines of your Song.");
        String line = null;
        //Scanner keyboard = new Scanner(System.in);
        int count;

        for (count = 1; count <= 3; count++) {
            System.out.println("\nEnter line " + count + ": ");
            line = keyboard.nextLine();
            outputStream.println(count + "\t" + line);
        }

        outputStream.close();
        System.out.println("\nYour Song has been written to the file song.txt.\n");
    } // end of main
} // end of class

My initial question was how do I Adjust the program so it first asks for a name of the file to write to. Use the Scanner class and its next() method. Read in the file name as a string variable after informing the reader the file name should end in the suffix .txt Eg:- Song with the file names Song1.txt,Song2.txt and Song3.txt. With the help of others I was able to have the scanner class and the next() in my code. Can someone please tell me why my code is not working?

Change this line

// Use "Song.txt"
outputStream = new PrintWriter("Song.txt");

to

// Use the value stored in the fileName1 String.
outputStream = new PrintWriter(fileName1);

Also, you're not getting the entire line with keyboard.next() you should something like this instead

fileName1 = keyboard.nextLine().trim();
