Is there any java utility to convert string to hex value (integer) ?

Initialize final Hex string as empty. Consider every character from input, cast it into integer. This integer value is ascii value of that character. Change this integer value into hexadecimal value and add this hexadecimal value to final Hex string.
Hex encoding is performed by converting the 8 bit data to 2 hex characters. The hex characters are then stored as the two byte string representation of the characters. Often, some kind of separator is used to make the encoded data easier for human reading.
Using the int() function: Using int(string, base=16) , we can convert the string to an integer with base 16 (Hexadecimal). Once we have the integer, we can use the inbuilt hex() function to convert an integer to a Hexadecimal number.
When you have a string starting with 0x or #
Integer.decode(hexStr);
is the goal
Or
Integer.parseInt(hexString, 16);
Is this what you are looking for?
Integer.toHexString(Integer.parseInt(String));
