การใช้งาน Collections และ Arrays

public class AllTheCities {

	public static void main(String[] args) {
		String[] euCapitals = {"Paris", "London", "Prague"};
		ArrayList capitals = new ArrayList();
        
        // Add cities to capitals all at once
		Collections.____(____, "Lima", "Bogota", "Santiago");
        // Convert euCapitals to List
        ____<____> euCapitalsList = Arrays.____(euCapitals);
        // Sort capitals
        ____.____(capitals);
        // Reverse capitals
        Collections.____(____);
        
		System.out.println(capitals);
		System.out.println(euCapitalsList);
		System.out.println(euCapitals);
	}
