Jetbrains Academy - Cinema Room Manager

My solutions for the Jetbrains Academy Problem Cinema Room Manager

https://hyperskill.org/projects/138

The solution is build up step by step over several stages. Stage 1 is the first and simple one. The following stages build up on the previous stages and get more and more advanced. There are five stages in total.

Because each stage is completely independent of the previous one, IntelliJ might show some warnings about duplicated code between the stages.
