Example

import java.util.*;
public class Main{
  public static void main(String[] args) {
        AbstractMap<String, String> abstractMap = new HashMap<>();
        abstractMap.put("hello-1", "Educative");
        abstractMap.put("hello-2", "edpresso");
        abstractMap.put("hello-3", "answers");
        System.out.println(abstractMap.values());
    }
}

Explanation

  • Line 5: We define an abstract map. The abstract map has the implementation of the hash map.
  • Lines 6–8: We use the put() method to add entries to the map.
  • Line 9: We invoke the values() method to obtain the values of the map. We then print these values.
