You should use

public class Youtube{

in your code(as class names are capitalized) and call the file Youtube.java.

System.out.printIn("hello youtube");  // capital 'I'

to

System.out.println("hello youtube");  // lowercase 'l'

And as has been mentioned already, in Java, the public class in a file must match the filename.
