    Default 'class' or 'interface' expected

    I am having another problem, when i entered in this code
    Java Code:
       private static boolean number(String Number, Interface, theStub){
           try{
               String List = theStub.getnumber();
               StringTokenizer tokens = new StringTokenizer (List);
               while (tokens.hasMoreTokens())
                    if (tokens.nextToken().equalsIgnoreCase(Number))
                        return true;
                    }catch (Exception e) {System.out.println("Error : " + e); } 
            return false;
        }
    It was throwing me back an error class or interface expected but i can not see the problem with the code, does anyone know where i am going wrong.

    Is this code in a class block?

    eg

    Java Code:
    class Class1 
    {
    
    private static boolean number(String Number, Interface, theStub){
           try{
               String List = theStub.getnumber();
               StringTokenizer tokens = new StringTokenizer (List);
               while (tokens.hasMoreTokens())
                    if (tokens.nextToken().equalsIgnoreCase(Number))
                        return true;
                    }catch (Exception e) {System.out.println("Error : " + e); } 
            return false;
        }
    
    }

    Well thats your problem.. Its definitely theStub class. I know you have removed the word theStub but dont forget to remove the other reference to it:

    Java Code:
    String List = theStub.getnumber();
    But obviousally without this none of the class will work...

    You need to write theStub class for any of this to work.

    Remove all of this:

    Java Code:
          try{
               String List = theStub.getnumber();
               StringTokenizer tokens = new StringTokenizer (List);
               while (tokens.hasMoreTokens())
                    if (tokens.nextToken().equalsIgnoreCase(Number))
                        return true;
                    }catch (Exception e) {System.out.println("Error : " + e); } 
            return false;
    and just run:

    Java Code:
    private static boolean number(String Number, Interface){
    
    }
    What happens?

    Does your client class have a 'main' method?

    I can't really see what the problem is. Can you post all the code for each class here.

    I just want all the code you are using so I can look at how it is coded. I cant work out why this is not working from what you have posted. Is there a lot of code? If there isnt that much then post it here. Otherwise zip it up.

    i said that i dont have a theStub class, with the application that i have, the first error is the class or interface expected.

    I have theStub line commented out so that it is not looking for that class

    Well not having theStub class is the least of your problems by the looks of it.

    I know you have removed theStub from

    Java Code:
    private static boolean number(String Number, Interface){
    But the rest of that code in the block relies on that class.

    None of this will work:

    Java Code:
           try{
               String List = theStub.getnumber();
               StringTokenizer tokens = new StringTokenizer (List);
               while (tokens.hasMoreTokens())
                    if (tokens.nextToken().equalsIgnoreCase(Number))
                        return true;
                    }catch (Exception e) {System.out.println("Error : " + e); } 
            return false;
    It is being called here:

    Java Code:
    String List = theStub.getnumber();
    Which you already commented out but with this removed, there is no 'List' which is needed for

    Java Code:
    StringTokenizer tokens = new StringTokenizer (List);
    You are going to need theStub for any of that to work.

    Even with that entire code block removed there are still errors as a result in the Client class.

    To be honist I have no idea. I removed the number method that has theStub code and there are other errors in the Client class. I commented them out and managed to compile it. This wont work as expected. I can't help you fix it any further.
