Can enums have string values?

A string object that can have only one value, chosen from the list of values ‘value1’, ‘value2’, …, NULL or the special ” error value. In theory, an ENUM column can have a maximum of 65,535 distinct values ; in practice, the real maximum depends on many factors. ENUM values are represented internally as integers.

You cannot create an object of an enum explicitly so, you need to add a parameterized constructor to initialize the value(s) . The initialization should be done only once. Therefore, the constructor must be declared private or default. To returns the values of the constants using an instance method(getter).5 Tem 2019

The Enum constructor can accept multiple values . Similarly, we can add any values we want to the enum, such as the proper case symbols, “He”, “Li” and “Be”, for example.2 Eyl 2021

Numeric enums are number-based enums i.e. they store string values as numbers. Enums are always assigned numeric values when they are stored. The first value always takes the numeric value of 0, while the other values in the enum are incremented by 1.

No they cannot . They are limited to numeric values of the underlying enum type. +1 Good one with the helper method! ToString(“F”) is useful for formatting to the name of the enum value, if they don’t want custom strings.

Learn to create Java enum where each enum constant may contain multiple values . We may use any of the values of the enum constant in our application code, and we should be able to get the enum constant from any of the values assigned to it.

Methods and variables in an enumeration Enumerations are similar to classes and, you can have variables, methods, and constructors within them .
