Java Set iterator with example
In this tutorial we will see how to use the Java iterator with Set interface . We will create an example to display the contents of the set collection.
In this tutorial we will see how to use the Java iterator with Set interface . We will create an example to display the contents of the set collection.
- Java Set Interface keeps the data without duplicate value.
- Its one subtype Treeset always returns sorted data.
- But the subtype HashSet doesnot return sorted data.
- It uses iterator() method to traverse the data
Example of Java Set Iterator
import java.util.*;
public class setiterator {
public static void main(String[] args) {
Set s = new TreeSet();
s.add(1000);
s.add(400);
s.add(900);
s.add(700);
s.add(400);
Iterator it = s.iterator();
while (it.hasNext()) {
System.out.println(it.next());
}
}
}
Output
400 700 900 1000
