iterate through hashMap by forEach loop

Comment

import java.util.HashMap;
import java.util.Map.Entry;

class Main {
  public static void main(String[] args) {

    // create a HashMap
    HashMap<Integer, String> languages = new HashMap<>();
    languages.put(1, "Java");
    languages.put(2, "Python");
    languages.put(3, "JavaScript");
    System.out.println("HashMap: " + languages);

    // iterate through keys only
    System.out.print("Keys: ");
    for (Integer key : languages.keySet()) {
      System.out.print(key);
      System.out.print(", ");
    }

    // iterate through values only
    System.out.print("\nValues: ");
    for (String value : languages.values()) {
      System.out.print(value);
      System.out.print(", ");
    }
    
    // iterate through key/value entries
    System.out.print("\nEntries: ");
    for (Entry<Integer, String> entry : languages.entrySet()) {
      System.out.print(entry);

langTable.put("H", "Hibernate");
 
// Iterating HashMap using foreach
