In order to improve the efficiency of the interview process, it is convenient to write a function in Java to convert the string into an integer. Give me a quick look at the code basics.Requirement: Do not call conversion functions such as parseint.

1. Gets the hexadecimal value of each character in the ' string '.2. Gets the character that corresponds to each value in the hexadecimal string. 、3. Convert the hexadecimal string to shaping.4. Converts a hexadecimal string to a floating-point type.

Int. Parse is converting string to intConvert.ToInt32 is the conversion of objects that inherit from object to int.You get an object, you want to convert it to int, with Int. Parse is not, you have to use Convert.ToInt32.Convert.ToInt32 () and Int.
