Byte[] to char[]

byte, char, java

Solution

Why you need to stick to strings, use array of char array, first append extra 0 in case its short and If your data is in byte format, use `bytes1.toString()` and then something like this,

public class Example {

    public static void main(String args[])
    {
        String[] byte1 = {"2","45","56","1"};
        for (int i = 0; i < byte1.length; i++) {
            if(byte1[i].length()<2){
                byte1[i] = "0"+byte1[i];
            }
        }
        char[][] chr = new char[5][10];
        StringBuilder buffer = new StringBuilder();
        for(int i = 0; i < byte1.length;i++){
               chr[i] = byte1[i].toCharArray();
        }


    for (int i = 0; i < chr.length; i++) {
            System.out.println(chr[i]);
    }
    }
}

Problem

I am in a requirement of display raw byte data in char form, there are some issue I am stuck like for example [ 1, 32, -1, -1 ] ( byte data ) which when converted into char comes as [1, 3, 2, -, 1, - ,1] My requirement [ 1, 32, -1, -1 ] in char format. Intailly I used the command ``` StringBuilder buffer = new StringBuilder(); for(int i = 0; i < byte1.length;i++){ buffer.append(byte1[i]); } char[] c = buffer.toString().toCharArray(); ``` Didn't serve my requirement. Then I used ``` char dig = (char)(((int)'0')+ (-32)); it gave an invalid output ``` Kindly help in my requirement. Thanks in advance
