treeset order in java code example

Example 1: TreeSet in java

// java treeset example
import java.util.Iterator;
import java.util.TreeSet;
public class TreeSetExamples
{
   public static void main(String[] args)
   {
      TreeSet<String> ts = new TreeSet<String>();
      ts.add("red");
      ts.add("blue");
      ts.add("green");
      ts.add("red");
      Iterator<String> iterate = ts.iterator();
      while(iterate.hasNext())
      {
         System.out.println(iterate.next());
      }
   }
}

Example 2: java treeset sort

Set<String> set = new TreeSet<String>(new Comparator<String>() {

    public int compare(String one, String other) {
        // implement
    }

});
