What is character that equivalent to 00000000 in bytes?

I need to append character that 00000000 in byte in String builder. I need to put it into String Array and and read it again later. Example :

StringBuilder sBfNumRow = new StringBuilder();
sBfNumRow.append(""); //add char that 00000000 in byte
stObj [c] = sBfNumRow.toString(); // put into String array 
stObj [c] .getBytes // read it again later.

Can someone help me to do this?

A char and int can be casted to each other so use that technique.

To illustrate.

int a = 0;
char zero = a;

Or use 0 direct without '0'

char zero = 0;

And in your code it would be.

BfNumRow.append((char) 0); //add char that 00000000 in byte

That would be

BfNumRow.append((char) 0);

if you want specifically use the char type. This

BfNumRow.append(0);

will use StringBuilder.append(int).
