      Thank you so much for this tutorial.
      Your code does not work.:(
      Here is mine:
      import java.io.FileReader;
      import java.io.IOException;
      public class Main{
      public static void main(String[] args){
      try{
      FileReader reader = new FileReader("lyrics.txt");
      int data = reader.read();
      while(data!=-1 ){
      System.out.println((char) data);
      data = reader.read();
      }
      reader.close();
      }catch(FileNotFoundException e){
      e.printStackTrace();
      }catch (IOException e){
      e.printStackTrace();
      }
      }
      }
      There's also an issue with my code.
      I get this error message:
      "error(s).Main.java:17: error: cannot find symbol
      }catch(FileNotFoundException e){
      ^
      symbol: class FileNotFoundException
      location: class Main
      1 error"
      If anyone knows how I can fix my code, kindly let me know.

    Your videos are so helpful bro. Not only do your videos make so much more sense than any googling or even courses I can take, but you make so many of them and you even copy your code down in the description?! You definitely make the best coding tutorials out there. Thank you for the hard work and dedication!

    Yo just wanna say that GOD loved the world so much he sent his only begotten
    son Jesus to die a brutal death for us so that we can have eternal life
    and we can all accept this amazing gift this by simply believing in him (Jesus) asking for the forgiveness of your sins
    and forming a relationship with heavenly father.
