byte [] b = new byte [10];
b [0] = (byte) str; / / Here how to convert byte str ah ? so that the compiler does not pass
/ / 0XCC is read out from the database string
------ Solution ------------------- -------------------------
str.getBytes ()
------ Solution ------- -------------------------------------
String str="0XCC";
byte[] b = str.getBytes();
System.out.println((char)b[0]);
---- - For reference only ---------------------------------------
b [0 ] = (byte) "0XCC". getBytes (); / / compiler is not passed ah
------ For reference only ----- ----------------------------------
b [0] = (byte) "0XCC". getBytes (); compiler does not pass ah
------ For reference only - -------------------------------------
you doing ah strong turn directly b = str.getBytes ();
