Print a byte array as a String

Demo Code

//package com.java2s;

public class Main {
    public static void main(String[] argv) throws Exception {
        byte[] bytes = new byte[] { 34, 35, 36, 37, 37, 37, 67, 68, 69 };
        System.out.println(toString(bytes));
    }// w  ww  .  ja  v a 2s .co  m

    /**
     * Print a byte array as a String
     */
    public static String toString(byte[] bytes) {

        StringBuilder sb = new StringBuilder(4 * bytes.length);
        sb.append("[");

        for (int i = 0; i < bytes.length; i++) {
            sb.append(unsignedByteToInt(bytes[i]));
            if (i + 1 < bytes.length) {
                sb.append(",");
            }
        }

        sb.append("]");
        return sb.toString();
    }

    /**
     * Convert an unsigned byte to an int
     */
    public static int unsignedByteToInt(byte b) {
        return (int) b & 0xFF;
    }
}
