Creating a LinkedHashMap and adding elements to it and printing the elements

 

import java.util.LinkedHashMap;

import java.util.Map;

public class AddDemo {

public static void main(String[] args) {

//creating LinkedHashMap

LinkedHashMap<Integer, String> lhm = new LinkedHashMap<>();

//adding element to our LinkedHashMap

lhm.put(21, "Amit");

lhm.put(5, "Rahul");

lhm.put(13, "Veeru");

lhm.put(34, "Subhash");

lhm.put(19, "Saahil");

//printing values using for each loop

//insertion order is maintained in LinkedHashMap

for (Map.Entry m : lhm.entrySet()) {

System.out.println(

"key = " + m.getKey() + "," + "Value = " + m.getValue()

);

}

}
