In this task, you are being asked to write value returning methods in Java. Write a method named quartersToDollars. The method should accept an int argument that is a number of quarters and return the equivalent number of dollars as a double. For example, if you pass 4 as an argument, the method should return 1.0; and if you pass 7 as an argument, the method should return 1.75. Also, make sure the method only accepts positive integer arguments and returns a negative value of -999.99 for any negative arguments. You should detect a negative return value and print message that the input was incorrect.
