I am trying to convert string of 0 and 1 to byte[] to save this in file, and in next step read this from the file and convert to string of 0 and 1. I don't know how to write toByteArray(String input)

Something like this:

String input = "011100101110001101000";
byte[] array = toByteArray(input);//how to do it
String output = "";

for(byte b : array) 
    outputString += Integer.toBinaryString(b);

System.out.println(output);// 011100101110001101000

1.It's not Java. 2.What when binaryString.lenght() % 8 != 0 ? – M.Devan Oct 23 '20 at 08:49
