Implement the NameSurferEntry class

The NameSurferEntry class encapsulates the information pertaining to one name in the database. That information consists of two parts:

The name itself, such as “Sam” or “Samantha”
A list of 11 values indicating the rank of that name in each of the decades from 1900
to 2000, inclusive

The class definition begins with a constructor that creates an entry from the line of data
that appears in the NamesData.txt file. For example, the entry for Sam looks like this:

Sam 58 69 99 131 168 236 278 380 467 408 466

The idea behind the design of this constructor is that it should be possible to read a line of data from the file and then create a new entry for it using code that looks like this:

String line = rd.readLine();
NameSurferEntry entry = new NameSurferEntry(line);

Assemble the GUI interactors

If you look at the bottom of Figure 1, you will see that the region along the SOUTH edge of the window contains several interactors: a JLabel, a JTextField, and three JButtons. Since putting up interactors is something you haven’t done in previous assginments, you probably want to work on this step before it becomes complicated with all the other parts of the assignment. Thus, your first milestone is simply to add the interactors to the window and create an implementation for the actionPerformed method that allows you to check whether you can detect button clicks and read what’s in the text field.
The simplest strategy to check whether your program is working is to change the definition of the NameSurfer class so that it extends ConsoleProgram instead of Program, at least for the moment. You can always change it back later. Once you have made that change, you can then use the console to record what’s happening in terms of the interactors to make sure that you’ve got them right. For example, the figure below shows a possible transcript of the commands used to generate the output from Figure 1, in which the user has just completed the following actions: Continue reading “cs106a – Assignment #6 – Task #1”
