Help me really quick since i don't understand ish in Computer science and the teacher isnt very good at explaining shit.

Help me find whats wrong with this?

Code:
public class retail {

    public static void main (String[] args);
    
    //Get the user's amount of purchase.
    System.out.print ("What was the amount of the purchase?");
    amount = Keyboard.nextLine();
    
    
    
    
    }
    
    
    
}
I will probably update this thread with more help but help me fast please so i can get this hw done before walking dead.
