如何用十六进制ASCII符号中的修改替换ByteArray元素？

import javax.xml.bind.DatatypeConverter;

public class HexByteArrayReplacement {
    public static void main(String[] args) {
        byte[] byteArray = { 0x48, 0x65, 0x6C, 0x6C, 0x6F }; // Example ByteArray

        // Step 1: Convert ByteArray to hexadecimal string
        StringBuilder hexString = new StringBuilder();
        for (byte b : byteArray) {
            hexString.append(String.format("%02X", b));
        }

        // Step 2: Modify or replace hexadecimal characters
        String modifiedHexString = hexString.toString().replace("48", "41"); // Replace 'H' with 'A'

        // Step 3: Convert modified hexadecimal string back to ByteArray
        byte[] modifiedByteArray = DatatypeConverter.parseHexBinary(modifiedHexString);

        // Print the modified ByteArray
        for (byte b : modifiedByteArray) {
            System.out.print((char) b);
        }
    }
}
