Guidelines for Using Constants

Do's:

1. Define Constants in a Separate Class:
   Create a class specifically for constants to centralize their management and improve code readability.

   public class Constants { public static final int MYNTRA_INTEGRATION_TYPE = 18; }

2. Use Constants in Your Code:
   Utilize these constants wherever needed in your code instead of hardcoding values.

   Channel channel = getChannelByIntegrationType(Constants.MYNTRA_INTEGRATION_TYPE);

   This makes your code easier to maintain and reduces the risk of errors caused by magic numbers.

3. Group Related Constants Together:
   If you have multiple constants related to a specific feature or module, group them together in a nested static class or separate constant files.

   public class IntegrationTypes { public static final int MYNTRA = 18; public static final int AMAZON = 19; // Add more constants as needed }
   Channel channel = getChannelByIntegrationType(IntegrationTypes.MYNTRA);

4. Add Descriptive Comments:
   Provide comments for your constants to explain their purpose, especially if the constant names are not self-explanatory.

   public class Constants { // Integration type for Myntra public static final int MYNTRA_INTEGRATION_TYPE = 18; }

Don'ts:

1. Avoid Hardcoding Values Directly in Your Code:
   Do not use literal values directly in your code as it reduces readability and makes maintenance difficult.

   // Bad Practice Channel channel = getChannelByIntegrationType(18);

   If the value needs to change, you would have to find and replace it everywhere it is used.

2. Avoid Using Unclear or Ambiguous Constants:
   Make sure the names of your constants are clear and descriptive to avoid confusion.

   // Avoid this public static final int INT_TYPE_18 = 18; // Use this public static final int MYNTRA_INTEGRATION_TYPE = 18;

By following these guidelines, you can ensure your code is more maintainable, readable, and less error-prone.
