Iterate through elements of TreeSet in Java
First, create a TreeSet and add elements −
TreeSet<String> set = new TreeSet<String>(); set.add("34"); set.add("12"); set.add("67"); set.add("54"); set.add("76"); set.add("49");
Now, let us iterate through the elements −
Iterator<String> i = set.iterator(); while(i.hasNext()){ System.out.println(i.next()); }
The following is an example that iterate through elements of TreeSet −
Example
import java.util.*; public class Demo { public static void main(String args[]){ TreeSet<String> set = new TreeSet<String>(); set.add("34"); set.add("12"); set.add("67"); set.add("54"); set.add("76"); set.add("49"); System.out.println("TreeSet elements..."); Iterator<String> i = set.iterator(); while(i.hasNext()){ System.out.println(i.next()); } } }
Output
TreeSet elements... 12 34 49 54 67 76
