Suppose that a class RadioStation has been defined for storing information about radio stations. Each station object keeps track of its name (a string), its broadcast band (a string) and its station number (a real number). For example, there is a local station called KUOW that is an FM station broadcast on 94.9. The class includes the following members:

Name	Description
`private String name`	name such as `"KUOW"`
`private String band`	band such as "FM" or "AM"
`private double station`	station such as 94.9
`private RadioStation link`	link to simulcast partner station (`null` if none)
`public RadioStation(String name, String band, double number)`	constructs a station with given name, band, station #
`public String getName()`	returns the name
`public String getBand()`	returns the band
`public double getStation()`	returns the station number
`public String toString()`	returns a String representation of the radio station
`public void simulcast(RadioStation other)`	records that this station and the other are simulcasts

Your task is to modify the class to be Comparable by adding an appropriate compareTo method. Radio stations should be grouped together by band (e.g., all AM stations grouped together and all FM stations grouped together). Within a given band, the stations should be sorted by station number (e.g., FM 94.9 less than FM 96.5).

The broadcast band can be any arbitrary string. For example, it might be "AM" versus "FM" or might include subdivisions like "FM 1" and "FM 2" or might include other text like "XM" for satellite radio.
