Naming - CZECHGROUP.cz

Class Names Standard

In our codebase, class names MUST be declared using PascalCase. This convention aids in distinguishing class names from other types of identifiers at a glance.

Definition

PascalCase means starting each word with a capital letter, without spaces or underscores between words. It's also known as Upper Camel Case.

Example (Correct):

public class CustomerAccount {
    // Class name is in PascalCase
}

public class ShoppingCart {
    // Class name is in PascalCase
}

Example (Incorrect):

public class customerAccount {
    // Not using PascalCase
}

public class shopping_cart {
    // Not using PascalCase
}

Method Names Standard

For clarity and consistency, method names MUST be declared in camelCase. This standard applies across all our codebases, irrespective of the programming language.

Definition

camelCase starts with a lowercase letter, and each subsequent word starts with a capital letter, without spaces or underscores.

Example (Correct):

public void updateAccountBalance() {
    // Method name is in camelCase
}

private void saveUserPreferences() {
    // Method name is in camelCase
}

Example (Incorrect):

public void UpdateAccountBalance() {
    // Not using camelCase
}

private void save_user_preferences() {
    // Not using camelCase
}

Constant Names Standard

Constants within our codebase MUST be declared using SCREAMING_SNAKE_CASE to easily differentiate them from other types of variables.

Definition

SCREAMING_SNAKE_CASE involves writing all letters in uppercase, with underscores separating words.

Example (Correct):

public static final int MAX_USER_COUNT = 100;

private static final String API_KEY = "your-api-key-here";

Example (Incorrect):

public static final int MaxUserCount = 100; // Not using SCREAMING_SNAKE_CASE

private static final String apiKey = "your-api-key-here"; // Not using SCREAMING_SNAKE_CASE

Variable Names Standard

To maintain a consistent and readable codebase, all variable names MUST be declared in camelCase. This convention applies to local and global variables alike.

Definition

camelCase for variable names starts with a lowercase letter, with each subsequent word beginning with an uppercase letter, without spaces or underscores.

Example (Correct):

int accountBalance;
String userName;

Example (Incorrect):

int AccountBalance; // Not using camelCase
String user_name;   // Not using camelCase
