Constants naming conventions

Constant variable names should be written in upper characters separated by underscores. These names should be semantically complete and clear.
Example:
RED, YELLOW, MAX_PRIORITY, MAX_STOCK_COUNT
Make sure to use the final modifier with constant variables.
public final String SECURITY_TOKEN = "...";
 
public final int INITIAL_SIZE = 16;
 
public final Integer MAX_SIZE = Integer.MAX;
