I got the answer from here https://stackoverflow.com/questions/29989834/cant-get-a-stringbuffer-to-print
The issue is that the constructor of StringBuffer takes the argument as size. So instead you can do something like
StringBuffer sb = new StringBuffer(1);
sb.append(d);
So you need to append the character to the buffer then only can print out

Change your code to StringBuffer sb = new StringBuffer(""+d);

You need to append in StringBuffer
StringBuffer sb = new StringBuffer();
sb.append(d);
