You can flush the root user's priviliges in mysql cli.
> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
> FLUSH PRIVILEGES;java.sql.sqlexception: access denied for user
As you are creating a database from scratch, you could use:
Connection connection = DriverManager.getConnection("jdbc:mysql://localhost/?user=root&password=rootpassword");
PreparedStatement ps = connection.prepareStatement("CREATE DATABASE databasename");
int result = ps.executeUpdate();java.sql.sqlexception: access denied for user
