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) {
		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());
