Popular Names Grapher

Against all bureaucratic stereotypes, the Social Security Administration, provides a neat web site showing the distribution of names chosen for kids over the last 100 years in the US. Every 10 years, the data gives the 1000 most popular boy and girl names for kids born in the US. The data can be boiled down to a single text file as shown below. On each line we have the name, followed by the rank of that name in 1900, 1910, 1920, ... 2000 (11 numbers). A rank of 1 was the most popular name that year, while a rank of 997 was not very popular. A 0 means the name did not appear in the top 1000 that year at all. The elements on each line are separated from each other by a single space.

We see that "Sam" was #58 in 1900 and is slowly moving down. "Samantha" popped on the scene in 1960 and is moving up strong to #7. "Samir" barely appears in 1980, but by 2000 is up to #798. Ultimately, we want to graph each name's popularity as a bar graph.

We will use the following files in today's activity:

• Canvas.java
• NameRecord.java
• NameDatabase.java
• LabeledInput.java
• Main.java

You will be updating the first three classes, the last one simply starts the program (you will not need to update it). You can use Eclipse to download these files to your machine by choosing the classwork project named namesurfer. When compiled and run, it should display an almost empty window.

To make the program work, complete the following methods:

1. Complete the accessor methods, getName and getRank, for the NameRecord class.
2. Complete the constructor for the class NameRecord.
3. Complete the constructor for the class NameDatabase.
4. Complete the match methods for the NameRecord class, then the NameDatabase class.
5. Complete the getPercent method for the Canvas class.
