How to Leverage Java Enums for Meaningful UI Labels and DB Mapping
This article explains how to define Java enum classes, demonstrates their usage with code snippets, and shows a practical technique for converting numeric database values into readable Chinese labels for display in user interfaces.
Enum classes are defined as shown in the first image, where each enum constant can hold additional fields and methods.
The usage pattern is demonstrated in the second image, illustrating how to retrieve enum values and access their associated data.
For example, when numeric codes are stored in a database but need to be displayed as Chinese meanings in the UI, the approach shown in the third image can be applied to map those numbers to readable strings.
