java code error

hi, im getting a 'class or interface expected' error. here is the code. any help appreciated.
Use the '+' operator to concatinate strings. Ie.:
System.out.println("Welcome to the grade book for " + courseName);
System.out.println("Welcome to the grade book for " + courseName);
First... decare the import at the top of the file.
Second... it will still fail to compile. I can help no further unless you can convince me this is not homework

Does the import statement have to be at the very beginning of the file?

Imports should come before class definitions. Otherwize you get the error the OP is talking about. They do not have to be the top line however.

Now it will compile.
You can also do this...
ninth.java
import java.util.Scanner;public class ninth{ private class GradeBook { public void displayMessage(String courseName) { System.out.printf("Welcome to the grade book for \n %s \n",courseName); } } public static void main(String args[]) { Scanner input = new Scanner(System.in); GradeBook myGradeBook = new GradeBook(); System.out.println(" Please enter the course name:"); String nameOfCourse = input.nextLine(); System.out.println(); myGradeBook.displayMessage(nameOfCourse); } }This topic is closed to new replies.
