Java & MySQL - Create Database Example

This tutorial provides an example on how to create a Database using JDBC application. Before executing the following example, make sure you have the following in place −
You should have admin privilege to create a database in the given schema. To execute the following example, you need to replace the username and password with your actual user name and password.

The following steps are required to create a new Database using JDBC application −
Import the packages − Requires that you include the packages containing the JDBC classes needed for database programming. Most often, using import java.sql.* will suffice.

Copy and paste the following example in TestApplication.java, compile and run as follows −
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;

public class TestApplication {
   static final String DB_URL = "jdbc:mysql://localhost/";
   static final String USER = "guest";
   static final String PASS = "guest123";

   public static void main(String[] args) {
      // Open a connection
      try(Connection conn = DriverManager.getConnection(DB_URL, USER, PASS);
         Statement stmt = conn.createStatement();
      ) {		      
         String sql = "CREATE DATABASE STUDENTS";
         stmt.executeUpdate(sql);
         System.out.println("Database created successfully...");   	  
      } catch (SQLException e) {
         e.printStackTrace();
      } 
   }
}
Now let us compile the above example as follows −
C:\>javac TestApplication.java
C:\>

When you run TestApplication, it produces the following result −
C:\>java TestApplication
Database created successfully...
C:\>
