Lab 1

Set Up Instructions

• System A
  • cd src/main/java/Lab1/SystemA
  • javac *.java
  • java Plumber

  The output file is located at src/main/java/Lab1/SystemA/OutputA.csv

• System B
  • cd src/main/java/Lab1/SystemB
  • javac *.java
  • java Plumber

  The output file is located at src/main/java/Lab1/SystemB/WildPoints.csv and src/main/java/Lab1/SystemB/OutputB.csv.

Notes:

• To use different input test cases, you need to change the variable named fileName at SourceFilter.java. The default file used is .../Lab1/DataSets/FlightData.dat.
• For the implementation in System B, I changed the id of "incorrect" altitude from 2 to 6. Since 6 is an unused value of each id, so when the SinkFilter reaches a data with an id of 6 afterward, the program will know the data was changed previously and should append a * at the end of the data when writing this record to the CSV file on local disk.
• In my implementation, if the altitude was changed, then the previous altitude for the next altitude to compare with will be its updated value, instead of the original one.
• The output csv files from the case I was provided with are also available at src/main/java/Lab1/MyCaseOutput. The original non-truncate intermediate files are at .../MyCaseOutput/RawResultsWithoutTruncating.
