hello everybody, there is a method which iterates trough map and returns string represantation of it. I get following errors:

public String getMatchInfo(int scheduleSize)
    {[INDENT]         if (matchMap.size() == 0)
        {[INDENT]             return "Schedule of stadium " + stadiumName + " is empty";
[/INDENT]}
        else
        {[INDENT]             String schedule = "Schedule of stadium " + stadiumName + ":\n";
            Iterator it = matchMap.entrySet().iterator();

            switch (scheduleSize)
            {[INDENT]                 case 0:
                    while (it.hasNext())
                    {[INDENT]                         HashMap.Entry<Integer, Match> pairs = (HashMap.Entry<Integer, Match>)it.next(); //error there: The type HashMap.Entry is 
     //not visible
                        schedule += (pairs.getValue()).getPreMatchInfo();
                        schedule += "\n";
[/INDENT]}
                default:
                    int i = 0;

                    while (it.hasNext())
                    {[INDENT]                                   i++;
          if (i > matchMap.size())[INDENT]          break;
[/INDENT]HashMap.Entry<Integer, Match> pairs = (HashMap.Entry<Integer, Match>)it.next(); // Error there: The type HashMap.Entry is 
     //not visible
                        schedule += (pairs.getValue()).getPreMatchInfo();
                        schedule += "\n";
[/INDENT]}
[/INDENT]}
return schedule;
[/INDENT]}
[/INDENT]}

HashMap is imported

please , can you post the full source with clear signature ? I think if you do it, I will able to help you

What does the 'matchMap' contain? What are the data types of the key and value?

Also the type is not visible may indicate that you're missing an import statement. Assuming the code is correct this import statement may look like:
import packagename.Match;

Try using Map.Entry instead of HashMap.Entry. While HashMap does implement the Map interface, that probably doesn't mean that HashMap will work to reference Map.Entry. You'll need to import Map to do this as well.
