Code formatting

The source code should be formatted according to default settings of the last version of IntelliJ IDEA.

Naming convention

• Classes

  We are using UpperCamelCase. We want to describe as good as possible what class defines. We are using nouns to show what class defines.

• Methods

  We are using camelCase. We want to describe as good as possible what does the method do. We are using verbs to show what does the method do. In case of boolean methods we are using names such as "isApplicationValid()". 

• Variables

  We are using camelCase. We want to describe as good as possible what variable represents. We are using verbs epithets to show variable represents. In case of boolean variable we are using names such as "isCorrect".
