Write three overloaded methods, at a minimum each method must take a String and an int
argument. Each method should do the following:
Returns the code 999 if the string argument contains the word gun.
Prints the number of characters in the string argument.
Prints the starting index of the first occurrence of the pattern ing found in the string argument.
Prints the string argument in all lower case.
Prints a message indicating if the integer passed in is even or odd.
Prints the character at index x of the String argument , where x is the int argument passed into
the method. If the int argument is larger than the string itself, print a message indicating this
case.
