Chapter: Collections Last Updated: 11-05-2016 18:26:11 UTC

Program:

            /* ............... START ............... */
                
import java.util.LinkedHashMap;
import java.util.Set;
import java.util.Iterator;
import java.util.Map;

public class JavaLinkedHashMapExample {

	public static void main(String args[]) {
		// HashMap Declaration
		LinkedHashMap<Integer, String> linkedHashMap = new LinkedHashMap<Integer, String>();

		// Adding elements to LinkedHashMap
		linkedHashMap.put(10, "Tony");
		linkedHashMap.put(23, "Jack");
		linkedHashMap.put(2, "Mark");
		linkedHashMap.put(2, "Sharon");
		linkedHashMap.put(5, "Tim");

		// Generating a Set of entries
		Set set = linkedHashMap.entrySet();

		// Displaying elements of LinkedHashMap
		Iterator iterator = set.iterator();
		while (iterator.hasNext()) {
			Map.Entry me = (Map.Entry) iterator.next();
			System.out.print("Key is: " + me.getKey() + "& Value is: " + me.getValue() + "\n");
		}
	}
}

                /* ............... END ............... */
        

Output

Key is: 10& Value is: Tony
Key is: 23& Value is: Jack
Key is: 2& Value is: Sharon
Key is: 5& Value is: Tim
