Enum Representation in Java
Senegal is divided into 14 regions. Below is an enum representation of these regions with their respective codes:
java
public enum Region {
DAKAR("DK"),
DIOURBEL("DI"),
FATICK("FA"),
KAOLACK("KA"),
KEDOUGOU("KE"),
KOLDA("KO"),
LOUGA("LO"),
MATAM("MA"),
SAINT_LOUIS("SL"),
SEDHIOU("SE"),
TAMBACOUNDA("TA"),
THIES("TH"),
ZIGUINCHOR("ZI");
private final String code;
Region(String code) {
this.code = code;
}
public String getCode() {
return this.code;
}
}
In the code:
- The enum
Region defines the 14 regions of Senegal along with their respective codes.
- Each region is associated with a two-character abbreviation.
- The
getCode() method allows you to retrieve the region code.
SQL Representation for Storing Region Data
To store the regions of Senegal in a database, you can create a table and insert the data using the following SQL:
sql
-- Table definition for storing regions of Senegal
CREATE TABLE regions (
id INT AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(100) NOT NULL,
code CHAR(2) NOT NULL
);
-- Inserting data for regions of Senegal
INSERT INTO regions (name, code) VALUES
('Dakar', 'DK'),
('Diourbel', 'DI'),
('Fatick', 'FA'),
('Kaolack', 'KA'),
('Kedougou', 'KE'),
('Kolda', 'KO'),
('Louga', 'LO'),
('Matam', 'MA'),
('Saint Louis', 'SL'),
('Sedhiou', 'SE'),
('Tambacounda', 'TA'),
('Thies', 'TH'),
('Ziguinchor', 'ZI');
In the SQL:
- We define a
regions table with columns id (auto-incremented), name (the name of the region), and code (the abbreviation for the region).
- The
INSERT INTO statement adds the regions of Senegal along with their respective codes into the table.
This setup ensures that you can efficiently store and query the regions of Senegal, both in your Java application (via enums) and in a relational database system.
