System out println new String new byte     byte 0x63     US-ASCII       Note especially that converting bytes to Strings always involves an encoding  If you do not specify it  you ll be using the platform default encoding  which means the code can break when running in different environments

If it s a single byte  just cast the byte to a char and it should work out to be fine i e  give a char entity corresponding to the codepoint value of the given byte  If not  use the String constructor as mentioned elsewhere   char ch    char 0x63  System out println ch

You can use printf   System out printf  string  c n   0x63     You can as well create a String with such formatting  using String format   String s   String format  string  c   0x63

you can use  the character equivalent to 0x63 is  c  but byte equivalent to it is 99  System out println  byte    char 0x63

The string ctor is suitable for this conversion   System out println  string     new String new byte    0x63

You have to construct a new string out of a byte array  The first element in your byteArray should be 0x63  If you want to add any more letters  make the byteArray longer and add them to the next indices   byte   byteArray   new byte 1   byteArray 0    0x63   try       System out println  string     new String byteArray   US-ASCII       catch  UnsupportedEncodingException e           TODO  Handle exception      e printStackTrace        Note that specifying the encoding will eventually throw an UnsupportedEncodingException and you must handle that accordingly

Use char instead of byte   System out println  string      char 0x63     Or if you want to be a Unicode puritan  you use codepoints   System out println  string     new String new int    0x63    0  1      And if you like the old skool US-ASCII  every byte is a character  idea   System out println  string     new String new byte     byte 0x63                                              StandardCharsets US ASCII      Avoid using the String byte    constructor recommended in other answers  it relies on the default charset  Circumstances could arise where 0x63 actually isn t the character c
