• Clone the repository.

  git clone https://github.com/vasilev02/Valentin-Vasilev-employees

  mvn assembly:single

• Go to target directory and to start the jar either use this command in terminal or if you navigate to the absolute path you can double click it and it will start.

Functionallity

The user picks up a file from the file system and, after selecting it, all common projects of the pair who have worked together on common projects for the longest period of time are displayed in a brief information with datagrid. We support different Date formats. The calculation is being computed in days.

User interface

UI is simple structure from Java Swing API. It contains button for uploading csv files which listens all the time for interact with files. After we upload file we will see information about longest working pair in two containers. First container inludes all common projects of the pair are displayed in datagrid with the following columns: Employee ID #1, Employee ID #2, Project ID, Days worked. Second is text area with infomration about the employees id, total count projects, respectively total days count calculated in days. There is a info also about the weeks, months and years if there are employees working for a very long time. The last one shows every project with it's id and worked days related to it.

Error handling

For this part we have simple error handling coded. If you try to upload CSV file which is empty, with invalid dates or invalid structure like row without employee key or without either start date or end date it will throw exception with the related message.
