hashMap.entrySet();

/*Parameters: The method does not take any parameter.
  
The java.util.HashMap.entrySet() method in Java is used to create a set
out of the same elements contained in the hash map. It returns a set view
of the hash map or we can create a new set and store the map elements 
into them.*/
