Increment a Hex value (JAVA)

Hi,

can you increment a hex value in Java? i.e. "hex value" = "hex value"++

From stackoverflow

• What do you mean with "hex value"? In what data type is your value stored?

  Note that int/short/char/... don't care how your value is represented initially:

  int i1 = 0x10;
  int i2 = 16;
  

  i1 and i2 will have the exact same content. Java (and most other languages as well) don't care about the notation of your constants/values.

• Yes. All ints are binary anyway, so it doesn't matter how you declare them.

  int hex = 0xff;
  hex++;  // hex is now 0x100, or 256
  int hex2 = 255;
  hex2++; // hex2 is now 256, or 0x100
  

• It depends how the hex value is stored. If you've got the hex value in a string, convert it to an Integer, increment and convert it back.

  int value = Integer.parseInt(hex, 16);
  value++;
  String incHex = Integer.toHexString(value);
  

• Short answer: yes. It's

  myHexValue++;
  

  Longer answer: It's likely your 'hex value' is stored as an integer. The business of converting it into a hexadecimal (as opposed to the usual decimal) string is done with

  Integer.toHexString( myHexValue )
  

  and from a hex string with

  Integer.parseInt( someHexString, 16 );

• The base of the number is purely a UI issue. Internally an integer is stored as binary. Only when you convert it to human representation do you choose a numeric base. So you're question really boils down to "how to increment an integer?".
