A load balancer that uses observer pattern.

Following are the commands and the instructions to run ANT on the project:

Note: build.xml is present in src folder.

To clean: ant -buildfile src/build.xml clean

Description: It cleans up all the .class files that are generated when we compile the code.

To compile the code: ant -buildfile src/build.xml all

Description: Compiles your code and generates .class files inside the BUILD folder.

To run the code: ant -buildfile src/build.xml run -Darg0="sample_input.txt" -Darg1="output.txt"
