how can the output be in different lines without an endline?

#3

Hello, @blog8647988822. The output appears on different lines because of the println() method. It prints its arguments on a new line each time it’s called. If we used print() everything would be on the same line. See below:

public class LanguageFacts {
  public static void main(String[] args) {
    // Press enter or return on your keyboard after each semicolon!
    
    System.out.println("Java is a class-based language.");
    System.out.println("Java classes have a 'main' method.");
    System.out.println("Java statements end with a semicolon.");
    System.out.println("Programming is useful and fun!");
    System.out.print("Hi");
    System.out.print(" there");
    System.out.print(", Buddy!");
  }
}

Output:

Java is a class-based language.
Java classes have a ‘main’ method.
Java statements end with a semicolon.
Programming is useful and fun!
Hi there, Buddy!

Hope this helps!
