How to convert byte[] to Byte[] in java?

Code:

import java.util.Arrays;
 
public class BytesToBytes {
  public static void main(String[] args) {
 
    byte[] b = new byte[]{1,2,3,4,5,6,7,8,9};
    Byte[] B = new Byte[b.length];
    for (int i = 0; i < b.length; i++) {
        B[i] = Byte.valueOf(b[i]);
    }
 
    System.out.println("byte[] b: " + Arrays.toString(b));
    System.out.println("Byte[] B: " + Arrays.toString(B));
  }
}

Output:

$ java BytesToBytes
byte[] b: [1, 2, 3, 4, 5, 6, 7, 8, 9]
Byte[] B: [1, 2, 3, 4, 5, 6, 7, 8, 9]
