Write a reference class called Song. It represents a simple songconsisting of two sequences, one of durations and one of frequencies. Here is its API: public song this constructor creates a Song object with empty duration and frequency sequences. public void addFrequency (double frequency) :this method adds a frequency to the sequence of frequencies. public void add uration (double duration) this method adds a duration to the sequence of durations. public void play this plays the sequence of durations and frequencies. It does this by indexing through both sequences, calling the playTone method on each individual duration and frequency. n addition to those public methods above, place in your clas a private version of the playTone method from an earlier assignment. Its first line will be private void playTone(double frequency, double duration) Test your class by placing my Playsong java program into your song package. My program creates a Song object, reads a series of durations and frequencies from a file into it, and then calls the play method. You will also need to copy my march txt file into your Eclipse data folder
