public class Main {

public static void main(String[] args) {

Scanner scanner = new Scanner(System.in);

Integer num1 = scanner.nextInt();

Integer num2 = scanner.nextInt();

// Initialize an instance of SoftReference by passing num1 to the constructor

SoftReference<Integer> softReference = ...

// Initialize an instance of WeakReference by passing num2 to the constructor

WeakReference<Integer> weakReference = ...

num1 = null;

num2 = null;

System.out.println((int) Math.pow(/* print the sum here */, 2));
