In this section of tutorial we will learn how to create a sample java application using iterator.We will create an example to display the contents of the ArrayList using iterator
In this section of tutorial we will learn how to create a sample java application using iterator.We will create an example to display the contents of the ArrayList using iterator
- Java Sample Iterator interface makes the traversing of the elements easy.
- It works similar to the Enumeration.
- It has method next() and haswNext()
Java Sample Iterator Example
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
import java.util.Random;
public class sample {
public static void main(String[] args) {
List list = new ArrayList();
for (int i = 0; i < 5; i++) {
list.add((float)Math.random() * 100);
}
Iterator i = list.iterator();
while (i.hasNext()) {
System.out.print(i.next() + "\t");
}
}
}
Output :
20.235153 18.181171 13.668783 54.82365 93.62838
