    Default Compiling issues in the terminal?

    public class Site {
     
    private int siteNumber;
    private String reserved;
    private String Name;
    private String licensePlate;
    private String postalCode;
    private int partyNumber;
     
    public Site(int site, String res, String nam, String lic, String post, int party) {
     
    site = siteNumber;
    res = reserved;
    Name = nam;
    lic = licensePlate;
    post = postalCode;
    party = partyNumber;
    }
     
    public int getSite() {
    return siteNumber;
    }
     
    }
     
    public class Campsite {
       public static void main (String[] args) {
     
    Site site1 = new Site(5, "Reserved", "Caroline Strickland", "A13 F4G", "A1M 3A1", 5);
     
    System.out.println("it is" + site1.getSite());
     
    }
     
    }
     
    //site number (1 - 50)
    //is this a serviced or non-serviced site?
    //is the site reserved?
    //name of camper (last name, followed by first name)
    //license plate number (6 characters)
    //postal code
    //number in party

    With this code, when I compile it under that name Campsite.java, I always get one error saying:

    Campsite.java:1: class Site is public, should be declared in a file named Site.java
    public class Site"

    I do have a file called Site.class in my files though, so I'm wondering what's going wrong?

    The error message is very specific. There can only be one top-level public class in each source file. That class should also contain the main() method. Remove the 'public' from the Site class declaration and all should be well.

    Hello.
    It is not necessary or compulsory to have a main() in the top-level public class. It is optional.
    main() is compulsory for the class that we want to run at the command prompt. This class could be top-level or inner. It could be public or non-public. But of course the signature of main() must be public static void main(String[]).
    The following two pieces of code illustrate this:

    // Test.java (contains Test class and Run class)
    public class Test {
      public void doDisplay()  {
          System.out.println("doDisplay() of Test class");
      }
    }
     
    class Run  {
        public static void main(String s[])  {
            Test test=new Test();
            System.out.println("in main() of Run");
            test.doDisplay();
        }
    }
    In the above code, I can type,
    > java Run

    // Test1.java
    public class Test1 {
        public static void doPrint()  {
            System.out.println("doPrint() of Test1 class");
        }
     
         private static class Inner  {
            public static void main(String str[])  {
                System.out.println("in main() of Test1.Inner");
                doPrint();
            }
        }
    }

    In the above code, I can type,
    > java Test1\$Inner

    Thanks,
    Syed.

    This error was caused because you defined the classes in the same file, and the Campsite was closed before Site started. The solution is to define Site in a new file and not stuck in the bottom of the Campsite's file
