How to delete a line from a .txt file in node.js?

How can I fix my simple Java program?

• Okay, I only need help with reading the file or case 1 in the switch. I am supposed to use a void method but I don't know what to put in the parameters or what to return? Help? import java.io.*; import java.util.*; import java.text.*; public class MP3 { final int MAXsongs = 100; // max amount of info on a file final int MAXartists = 100; final int MAXalbums = 100; String[] Song = new String [MAXsongs]; // arrays for text String[] Artist = new String [MAXartists]; String[] Album = new String [MAXalbums]; String line = null; int countS = 0; // counter for songs in program int countB = 0; // counter for artists in program int countA = 0; // counter for albums in program public void Read (double output) throws IOException //to open and view the database { BufferedReader reader = new BufferedReader (new FileReader ("JonsData.txt")); System.out.println ("This is your music collection: "); while ((line = reader.readLine ()) != null) { Song [countS] = (line); line = reader.readLine (); Artist [countB] = (line); line = reader.readLine (); Album [countA] = (line); System.out.println (Song [countS]); // output read info to the screen System.out.println (); System.out.println (Artist [countB]); System.out.println (); System.out.println (Album [countA]); countS++; countB++; countA++; } reader.close (); } public static void main (String str[]) throws IOException { BufferedReader stdin = new BufferedReader (new InputStreamReader (System.in)); DecimalFormat df = new DecimalFormat ("#"); int menu; // switch System.out.println ("Welcome to your database"); System.out.println (); System.out.println ("1: Open and veiw your collection"); System.out.println ("2: Add a file to your collection"); System.out.println ("3: Search by: category, titles, artists"); System.out.println ("4: Sort by: category, titles, artists"); System.out.println ("5: Create a backup of the collection"); System.out.println ("6: Delete a song from the collection"); System.out.println ("7: Allow multiple users to create other databases as well"); System.out.println (); System.out.println ("Which option would you like to choose?"); // asks user to choose 1 of 7 options menu = Integer.parseInt (stdin.readLine ()); switch (menu) { case 1: Read (); break; case 2: break; case 3: break; case 4: break; case 5: break; case 6: break; case 7: break; default: System.out.println ("Not an option"); } } }

• Answer:

  It might actually be less effort to learn how to program rather than reposting your question every 20 minutes, incrementally getting it written for you.
