Java

Write a method called parseRational. It should take a single string argu- ment and return a double. The string argument will be a form similar to the arguments in the following example calls.

parseRational("1/4") returns 0.25, parseRational(" 14/ -2 ") returns 7.0. parseRational(" 28 / 56 ") returns 0.5.

Notice that the numerator and denominator may be surrounded by arbitrary whitespace. You may assume that the string is well formed and do not need to validate the input.

Hint: you can use the split method of string class to split a string into an array of strings and use Integer.parseInt to convert a string into a number. Also, remember to trim white spaces.
