Introduction to Java Programming Language

This repository contains my solutions to the homework tasks and the final exam for the Introduction to Java Programming Language course at the Faculty of Electrical Engineering and Computing, University of Zagreb.

Here is a brief description of each homework along with links to the homework's source code and its pdf. Most of the pdfs are partially or wholly in Croatian, so each pdf link says whether it is in Croatian, English or both.
