The integer class is used to convert binary data into hexadecimal data. The same is true for octal data.

Public static string bin2hex (string binstr) {int deci = integer. valueof (binstr, 2); Return integer. tohexstring (deci);} public static string hex2bin (string hexstr) {int deci = integer. valueof (hexstr, 16); Return integer. tobinarystring (deci );}

Public static void main (string ARGs []) {string STR = "f012"; system. out. println (hex2bin (STR); system. out. println (bin2hex ("01011011 "));}

Execution result:

1111000000010010
5b

Very simple

Same as octal Conversion
