Enum Representation in Java
Slovakia is divided into 8 regions. Below is an enum representation of these regions with their respective codes:
java
public enum Region {
BRATISLAVA("BA"),
KOŠICE("KE"),
PREŠOV("PO"),
TRENČÍN("TC"),
NITRA("NI"),
ŽILINA("ZA"),
TRNAVA("TA"),
BANSKÁ_BYSTRICA("BB");
private final String code;
Region(String code) {
this.code = code;
}
public String getCode() {
return this.code;
}
}
In the code:
- The enum
Region
defines the 8 regions of Slovakia 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 Slovakia in a database, you can create a table and insert the data using the following SQL:
sql
-- Table definition for storing regions of Slovakia
CREATE TABLE regions (
id INT AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(100) NOT NULL,
code CHAR(2) NOT NULL
);
-- Inserting data for regions of Slovakia
INSERT INTO regions (name, code) VALUES
('Bratislava', 'BA'),
('Košice', 'KE'),
('Prešov', 'PO'),
('Trenčín', 'TC'),
('Nitra', 'NI'),
('Žilina', 'ZA'),
('Trnava', 'TA'),
('Banská Bystrica', 'BB');
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 Slovakia along with their respective codes into the table.
This setup ensures that you can efficiently store and query the regions of Slovakia, both in your Java application (via enums) and in a relational database system.
