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;
import java.io.IOException;
import java.io.FileNotFoundException;
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();
}
}
}

Why reader.read(); didnt stop unless we put into data variable ?
Happy brother's day bro
Yoh bro I've been meaning to ask, what is e.printStackTrace()?
It will print the exception that occurs

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.
Bro? 😳

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.
