import java.util.Arrays;
public class osoo {
public int[] swapNumbers(int[] numbers) {
numbers[0] ^= numbers[1];
numbers[1] ^= numbers[0];
numbers[0] ^= numbers[1];
return numbers;
}
public static void main(String[] args){
int[] numbers =new int[2];
numbers[0] =1;
numbers[1] =2;
osoo ossn =new osoo();
ossn.swapNumbers(numbers);
System.out.println(Arrays.toString(numbers));
}
}
