Iterate through the values of Java LinkedHashMap in Java


An iterator is used in Java to iterate through the values of LinkedHashMap.

Let us first create LinkedHashMap −

LinkedHashMap<String,String> l = new LinkedHashMap<String,String>();

Add some elements to the LinkedHashMap −

l.put("1", "Jack");
l.put("2", "Tom");
l.put("3", "Jimmy");
l.put("4", "Morgan");
l.put("5", "Tim");
l.put("6", "Brad");

Iterate through the values −

Collection res = l.values();
Iterator i = res.iterator();
while (i.hasNext()){
   System.out.println(i.next());
}

The following is an example to iterate through the values of LinkedHashMap −

Example

 Live Demo

import java.util.*;
public class Demo {
   public static void main(String[] args) {
      LinkedHashMap<String,String> l = new LinkedHashMap<String,String>();
      l.put("1", "Jack");
      l.put("2", "Tom");
      l.put("3", "Jimmy");
      l.put("4", "Morgan");
      l.put("5", "Tim");
      l.put("6", "Brad");
      System.out.println("LinkedHashMap elements...");
      Collection res = l.values();
      Iterator i = res.iterator();
      while (i.hasNext()) {
         System.out.println(i.next());
      }
   }
}

Output

LinkedHashMap elements...
Jack
Tom
Jimmy
Morgan
Tim
Brad
