My code is giving me trouble......its telling it cant find variable length

 public void addTeam()
    {
        System.out.print("\nWould you like to add the teams to group 1 or 2: ");
        int selection = scan.nextInt(); 
        System.out.println("");
        
        for(int z = 1; z <= 4; z++)
        {
        System.out.print("Enter the name of the team: ");
        String name = scan.next();
        System.out.print("Enter the location of the team: ");
        String location = scan.next();
        System.out.println("");
        
        Team team = new Team(teamLocation, teamName);
        if(selection == 1){groupA.addTeam();}
           else 
           
           {groupB.addTeam();}        
        
        }
    
    for(int index = 0; index < groupB.length; index++)
    {
        boolean addTeamtoGroup = false;
        if(group[index] == null && addTeamtoGroup == false)
        {
            group[index] = team;
            addTeamtoGroup = true;
            // break;
        }
    }
    return true;
}

Where is the variable groupB declared? I'm guessing that since it isn't an array, that's your problem. Note that arrays have a variable length, Strings have a method length(), and Lists have a method size(), all of which are comparable.

[mega105wr]

Ive Declared it in the same class as this code is in....

I've declared it as

public static Group groupB = new Group();

.

so what should I do?

[macosxnerd101]

It sounds like the Group class doesn't have a length variable. Does it contain a List, array, or String that you could access a corresponding attribute for?

[japanir]

Well it could be helpfull if you posted the Group class, it's members, variables, to get a clear view of what you try to do.
especially, did you create a method to retrieve the current length\size of a Group Object?

Your Group class does not contain a variable length, and the arrays are local to the main() method. This isn't great class design, but I know I adressed this in your other thread as well as linked to tutorials illustrating good class design.

[Dogstopper]

You are trying to access Group.length which is not a static or local method or variable. In order to call that, you have to have a length attribute or a method to call.

Thanks so Much guys.....i got it now...really appreciate it .
