The java.util.Set.iterator() method is used to return an iterator of the same elements as the set. The elements are returned in random order from what present in the set.
Syntax:
Iterator iterate_value = Set.iterator();
Parameters: The function does not take any parameter.
Return Value: The method iterates over the elements of the set and returns the values(iterators).
Below program illustrate the java.util.Set.iterator() method:
import java.util.*;
public class SetDemo {
public static void main(String args[])
{
Set<String> set = new HashSet<String>();
set.add( "Welcome" );
set.add( "To" );
set.add( "Geeks" );
set.add( "4" );
set.add( "Geeks" );
System.out.println( "Set: " + set);
Iterator value = set.iterator();
System.out.println( "The iterator values are: " );
while (value.hasNext()) {
System.out.println(value.next());
}
}
}
|
Output:
Set: [4, Geeks, Welcome, To]
The iterator values are:
4
Geeks
Welcome
To
