Following are the commands and the instructions to run ANT on your project.

Note: build.xml is present in studentskills/src folder.

Instruction to clean:

ant -buildfile studentskills/src/build.xml clean

Description: It cleans up all the .class files that were generated when you compiled your code.

Instructions to compile:

ant -buildfile studentskills/src/build.xml all

The above command compiles your code and generates .class files inside the BUILD folder.

Instructions to run:

ant -buildfile studentskills/src/build.xml run -Dinput="input.txt" -Dmodify="modify.txt" -Doutput1="output1.txt" -Doutput2="output2.txt" -Doutput3="output3.txt" -Derror="error.txt" -Ddebug="debugValue"

Note: Arguments accept the absolute path of the files.

Description:

1. Assumption

• Format of line in input file should be as given format: <B_NUMBER>:<FIRST_NAME>,<LAST_NAME>,,,[,[, ...]]
• After (:) valuse are separated by coma(,) No spaces after and before coma(,)
• Bnumber should be 4 digit positive integer.
• Max number of skill that will be listed in the input file will be 10.
• Lines in input file can have repeated bnumbers.
• Format of line in modify file should be as given format: <REPLICA_ID>,<B_NUMBER>,<ORIG_VALUE>:<NEW_VALUE>
• Before (:) valuse are separated by coma(,) No spaces after and before coma(,)
• Modification file will not have any request to change the GPA.
• Order of input arguments to run command is input.txt, modify.txt, output1.txt, output2.txt, output3.txt, debug value.

2. Data structures:

• String are used to append the results that need to display.
• Set are used to store skills.
• List is used to store trees.

3. External Materials:

• Used BST algorithms reference: https://www.geeksforgeeks.org/binary-search-tree-set-1-search-and-insertion/

4. Code working:

• Input file is read line by line in the InputDataProcessor and values are split on (:) and are stored in respective variable.
• All values are passed to StudentRecord to store the values of student and object of that student is created.
• Created student obj is passed to TreeHelper to create node by sending student record to Node class to create Node and is return to clone that node for other tress.
• After cloning node observers of those nodes are registered and then send to Tree to insert node in tree to create tree using BST algorithm.
• After inserting node and creating tree Modify file is read line by line in InputDataProcessor and values are split at (:) and are stored in respective variables.
• Modified information is passed to TreeHelper to search the node based on bNumber and update the node information.
• After updating node notify its observers to update their nodes.
• After all insert and update all trees are stored in Results and are printed on StdOut and in respective output file.

5. Note:

• I have used 1 slack day from 5 slack days.
