HashMap elementlarini for-each sikli yordamida aylanib chiqing.

Eslatma: Faqat kalitlar kerak bo‘lsa, keySet() metodidan, faqat qiymatlar kerak bo‘lsa, values() metodidan foydalaning:

// Print keys
for (String i : capitalCities.keySet()) {
  System.out.println(i);
}

// Print values
for (String i : capitalCities.values()) {
  System.out.println(i);
}

// Print keys and values
for (String i : capitalCities.keySet()) {
  System.out.println("key: " + i + " value: " + capitalCities.get(i));
}
