Hello everyone i am having issues with my project:

here is the specifics of the project:

1. Read a data file, create the internal data structure, make a GUI to display the structure, and let the user search the structure.

2. Sort the structure, use hash maps to create the structure more efficiently.

3. make a thread for each job, cannot run until a ship has a dock, make a GUI to show the progress of each job.

4. Simulate competing for resources (persons with particular skills) for each job.

Project 2 General Objectives

Project 2 - Map class, Comparator, sorting

 Use the JDK Map class to write more efficient code when constructing the internal data structures from the data file.

 Implement SORTING using the Comparator interface together with the JDK support for sorting data structures, thus sorting on different fields of the classes from Project 1.

 Extend the GUI from Project 1 to let the user sort the data at run-time.
