Definition of done (DOD) for each task described separately, in each sub module(basic/advanced), but overall common rules are next

• Code inspection results (default Intellij Idea inspection profile). Zero or close to it warnings amount. The less warnings - the better(Java Doc related warnings can be omitted and not taken into account, you can disable it)
• Sonar Lint inspection. Same rules -zero or near to it issues amount is best.
• Unit tests. All existing tests should be with positive results. Adding new tests - additional plus.
