How to encode a phrase using aes?
Below is my code

import java.util.Scanner;

public class encrypt {

        public static void main (String[] args){
             Scanner e = new Scanner(System.in);

           String str = e.nextLine();
           String key = e.nextLine();
            byte[] encrypt1 = str.getBytes();
            byte[] encrypt2 = key.getBytes();
            byte[] result = new byte[str.length()];
            
            for (int i = 0; i < encrypt1.length; i++) {
                result[i] = (byte) (encrypt1[i] ^ encrypt2[i % encrypt2.length]);
                System.out.println(result);
            }
            
            }

        }

Whatever I don't encode always produces only this result:
