Write a Java method toDecimalString() that receives a string with hexadecimal symbols and returns another string where every hexadecimal symbol is converted individually to its decimal representation. If the received string contains a wrong hexadecimal value, it should return an error message. To test your method, write a main() method that enables the user to input a string in hexadecimal format, removes eventual extra spaces from it, and makes all characters of the string in upper case. Then, sends this string to toDecimalString() and displays the returned string (decimal format or error message). Hints: 1. To declare an empty string use: String newString = ""; 2. The hexadecimal system is composed of 16 symbols: 0 to 9 and A to F. a. To check if a character c is a digit you can use: Character.isDigit(c); b. The decimal representation of A is 10, B is 11, C is12, D is 13, E is 14, and F is 15. Run Example 1: Enter a hexadecimal string: 2gk Decimal value is: Wrong hexadecimal value (g) Run Example 2: Enter a hexadecimal string: 1f2bc9a Decimal value is: 1 15 2 11 12 9 10
