Write code to convert byte array To String

Convert each byte in the array to string

Hint

Use String.format() method to format the byte value

Demo

//package com.book2s;

public class Main {
    public static void main(String[] argv) {
        byte bytes = 42;
        System.out.println(bytesToString(bytes));
    }/*from  w  w w .ja v a 2 s . c  om*/

    public static String bytesToString(byte... bytes) {
        StringBuilder builder = new StringBuilder();
        for (byte aByte : bytes) {
            String binStr = Integer.toBinaryString(aByte);
            int length = binStr.length();
            if (length > 8) {
                builder.append(binStr.substring(length - 8)).append(" ");
            } else {
                builder.append(
                        String.format("%08d", Integer.parseInt(binStr)))
                        .append(" ");
            }
        }
        return builder.toString();
    }
}
