Great approach, @ishrth_fathima But if your java constant values are logically related, an enum is even better. Enums not only group constants but can also hold extra functionality.

public enum TimeConstants {
    MAX_SECONDS(25),
    MIN_SECONDS(5);

    private final int value;

    TimeConstants(int value) {
        this.value = value;
    }

    public int getValue() {
        return value;
    }
}

Then, use it like this:

java

CopyEdit

int timeout = TimeConstants.MAX_SECONDS.getValue();

:heavy_check_mark: Groups related constants

:heavy_check_mark: Ensures type safety

:heavy_check_mark: Allows additional behavior

:rotating_light: When to use?

:point_right: Best when constants belong to a category, like time limits or error codes."
