iterate through hashset in java code example

Example 1: iterate hashmap java

public static void printMap(Map mp) {
    Iterator it = mp.entrySet().iterator();
    while (it.hasNext()) {
        Map.Entry pair = (Map.Entry)it.next();
        System.out.println(pair.getKey() + " = " + pair.getValue());
        it.remove(); // avoids a ConcurrentModificationException
    }
}

Example 2: set iteration java

import java.util.HashSet;
import java.util.Iterator;

class IterateHashSet{ 
  public static void main(String[] args) {
     HashSet<String> hset = new HashSet<String>();
     hset.add("Chaitanya");
     hset.add("Rahul");
 
     Iterator<String> it = hset.iterator();
     while(it.hasNext()){
        System.out.println(it.next());
     }
  }
}
