Iterate through elements of HashSet in Java
Create a HashSet and add elements to it −
Set<Integer> hs = new HashSet<Integer>(); hs.add(20); hs.add(39); hs.add(67); hs.add(79); hs.add(81); hs.add(87);
Try the below given code to iterate through the elements −
Iterator i = hs.iterator(); while (i.hasNext()) System.out.println(i.next());
To iterate through the elements of HashSet, try the following code −
Example
import java.util.*; public class Demo { public static void main(String args[]) { Set<Integer> hs = new HashSet<Integer>(); hs.add(20); hs.add(39); hs.add(67); hs.add(79); hs.add(81); hs.add(87); hs.add(88); System.out.println("Elements = "+hs); Iterator i = hs.iterator(); while (i.hasNext()) System.out.println(i.next()); } }
Output
Elements = [81, 67, 20, 39, 87, 88, 79] 81 67 20 39 87 88 79
