- Java HasNext Iterator is the method of the Iterator Interface.
- It returns the boolean.So it is used in the loop to traverse the next value.
- In case of false vale loop terminates.
Java HasNext Iterator Example
import java.util.ArrayList;
import java.util.Iterator;
public class hasnext {
public static void main(String[] args) {
String months[] = { "jan", "feb", "march", "april", "may", "june" };
ArrayList list = new ArrayList();
for (String m : months) {
list.add(m);
}
Iterator iterator = list.iterator();
while (iterator.hasNext()) {
System.out.println(iterator.next());
}
}
}
Output
jan feb march april may june
