Set iterator() method in Java with Examples
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
