A. Files required: 1. Art.java 2. p7arts.txt & p7artists.java (Input files to read from) 3. out2.txt (Output file to write to)

B. Java programs needed to write: 1. ArtistWork.java: - It extends Art class and implements Comparable Interface (need to create the interface) and consists of the following: i) An extra field "artistName" ii) A constructor that accepts the four fields of Art and artistName iii) toString() methods: to print the values of 5 fields iv) compareTo(Artistwork o) : So that the list can be sorted according to "artId" and then "artistId".

2. MyArtList.java: - It contains the following: i) list - an Arraylist of ArtistWork ii) "artistList" to find artistName based upon artistId iii) Constructor that accepts the file Name so that the list can be constructed upon reading the file. iv) findName() : a method that finds artistName from artistList based on the supplied artistId. v) Two print() methods to print the content to output file and to the console.

c. Construct Step1.java that contans only the following code: public class Exam3Step1 { public Exam3Step1() { MyArtList myArts = new MyArtList("p7artists.txt"); myArtists.print("Name", "exam3out1.txt"); }

}

D. "Main.java" that calls "Step2" which will produce an output file "out2.txt"

E. Attach the output when answering.

Sample output for Step 2: (Only for reference) (Incomplete)

ArtistID = 1, ArtistName = Acconci, ArtID = 1038, ArtTitle = Spring FLowers, Appraised Value = 800

ArtistID = 1, ArtistName = Acconci, ArtID = 1050, ArtTitle = Cattle Ranch, Appraised Value = 10000

ArtistID = 1, ArtistName = Acconci, ArtID = 1103, ArtTitle = Trail End, Appraised Value = 8000

ArtistID = 2, ArtistName = Budd, ArtID = 1042, ArtTitle = Coffee on the trail, Appraised Value = 7544

and so on for other ArtistID ....
