Iterator Java While
This segment of tutorial illustrates about the while loop and its use with the Iterator interface.We will create an example to print the content of the a ArrayList using the while loop.

- The Java While loop Iterator is the top tested loop.
- It is in two forms while(), do while()
- While loop is mostly used with Iterator compared to for loop
Java While Loop Iterator Example
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
public class while1 {
public static void main(String[] args) {
List l = new ArrayList();
for (int i = 10; i <= 50; i += 10) {
l.add(i);
}
Iterator it = l.iterator();
System.out.println("while loop");
while (it.hasNext()) {
System.out.print(it.next() + "\t");
}
Iterator it1 = l.iterator();
System.out.println("\ndo .. while");
do {
System.out.print(it1.next() + "\t");
} while (it1.hasNext());
}
}
