Task #3 Arrays of Objects 1. Copy the files Song java (see Code Listing 7.1), Compact Disc.java (see Code Listing 7.2) and Classics.txt (see Code Listing 7.3) from the Student Files or as directed by your instructor. Song.java is complete and will not be edited. Classics.txt is the data file that will be used by Compact Disc.java, the file you will be editing. 2. In Compact Disc.java, there are comments indicating where the missing code is to be placed. Declare an array of Songs, called cd, with a size of 6. 3.
