Example of Java Arraylist Iterate
import java.util.*;
public class javaarray {
public static void main(String[] args) {
List list = new ArrayList();
list.add("aaaa");
list.add("bbbb");
list.add("cccc");
list.add("dddd");
Iterator i = list.iterator();
while (i.hasNext()) {
System.out.print(i.next() + "\t");
}
}
}
Output
aaaa bbbb cccc dddd
