How to Add Key-Value pairs to LinkedHashMap in Java?

// Java Program to add key-value 
// pairs to LinkedHashMap
import java.util.*;
public class Main {
  
    public static void main(String[] args)
    {
        // create an instance of LinkedHashMap
        LinkedHashMap<Integer, Integer> map
            = new LinkedHashMap<Integer, Integer>();

        int num, key, val;
        num = 2;
        for (int i = 0; i < num; i++) {
          
            // Taking inputs from user
            key = i + 1;
            val = key * 10;

            // Add mappings using put method
            map.put(key, val);
        }
        // Displaying key
        System.out.println("Keys: " + map.keySet());

        // Displaying value
        System.out.println("Values: " + map.values());

        // Displaying key-value pair
        System.out.println("Key-Value pairs: "
                           + map.entrySet());
    }
}
