Hey bro can you make a tutorial on playing sounds in java? I want to add some music and sound effects to my GUI...
Love this channel.
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.
@@joyceasante8292 i think you forgot to add
import java.io.FileNotFoundException;
Issue fixed! Thanks@Chan.
import java.io.FileReader;

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();
}
}

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!

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.

Not well explained for a beginner
I don’t think it gets much easier than that, maybe you need to review some core concepts first.
