Casting an int from a sorted set

[Bmack]

Hi,
trying to write a method that will return an int from a sorted set. I get a messasge "Semantic error: java.lang.String cannot be cast to java.lang.Integer". Is there any way in which I can return an int?


[code]
public int getLowestValueInSet()
{
TreeSet tSet = new TreeSet();
tSet.add("7")
tSet.add("3");
tSet.add("4");
// System.out.println("Lowest value in Java TreeSet is : " + tSet.first());
int lowestValue=(Integer)tSet.first();
return lowestValue;
}
[code]

Maybe this:

TreeSet<Integer> tSet = new TreeSet<Integer>();
tSet.add(new Integer(7));
tSet.add(new Integer(4));
tSet.add(new Integer(3));

Thanks, that worked a treat. I applied your solution to the method that created the set I was using and it all worked. Thanks for taking the time to reply.

F.Y.I.

public SortedSet makeCalendar(int [] suppliedDays)
{
   SortedSet<Integer> calendar = new TreeSet<Integer>();
   for (Integer aDay : suppliedDays)
   { 
      calendar.add(new Integer(aDay));
   }
      return calendar;
   }
}
