Problem 24: Baseball Statistics
The local Kids’ League coach keeps some of the baseball team statistics in a text
file organized as follows: each line of the file contains the name of the player
followed by a list of symbols indicating what happened on each at bat for the
player. The letter h indicates a hit, o an out, w a walk, and s a sacrifice fly. Each
item on the line is separated by a comma. There are no blank spaces except in
the player name. So, for example the file could look as follows:
Sam Slugger,h,h,o,s,w,w,h,w,o,o,o,h,s
Jill Jenks,o,o,s,h,h,o,o
Will Jones,o,o,w,h,o,o,o,o,w,o,o
The file BaseballStats.java contains the skeleton of a program thats reads and
processes a file in this format. Study the program and note that three Scanner
objects are declared.
• One scanner (scan) is used to read in a file name from standard input.
• The file name is then used to create a scanner (fileScan) to operate on that file.
• A third scanner (lineScan) will be used to parse each line in the file. Also note
that the main method throws an IOException. This is needed in case there is a
problem opening the file. Complete the program as follows:
1. First add a while loop that reads each line in the file and prints out each part
(name, then each at bat, without the commas) in a way similar to the
URLDissector program in Listing 5.11 of the text. In particular inside the loop you
need to a. read the next line from the file b. create a comma delimited scanner
(lineScan) to parse the line c. read and print the name of the player, and finally,
d. have a loop that prints each at bat code.
2. Compile and run the program to be sure it works.
