การใช้งาน HashMap

// Import HashMap
import java.____.____;

public class EmployeeDirectory {

	public static void main(String[] args) {
		// Create a HashMap directory of Integer to String using parameterized constructor
		HashMap<_____, ____> directory = new ____<____, ____>();
		directory.put(23, "Joye");
		// Add employee "Marcia" with id 31 to the directory
		directory.____(____, "____");
		directory.put(45, "Davy");
		System.out.println(directory);
		String name = directory.get(31);
		System.out.println(name);
		// Remove "Davy" from the directory
		directory.____(____);
		System.out.println(directory);
	}
