JDBC (Java Database Connectivity) is the standard Java API for database-independent connectivity between the Java programming language and a wide range of databases.

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public class JdbcExample {
    public static void main(String[] args) {
        try {
            Connection con = DriverManager.getConnection(
                    "jdbc:mysql://localhost:3306/mydb", "user", "password");
            Statement stmt = con.createStatement();
            ResultSet rs = stmt.executeQuery("select * from emp");
            while (rs.next())
                System.out.println(rs.getInt(1) + "  " + rs.getString(2) + "  " + rs.getString(3));
            con.close();
        } catch (Exception e) {
            System.out.println(e);
        }
    }
