  • (1) I guess your connection is null. You are using `connection.createStatement()` without first checking whether the connection is null. (2) `Connection connection = DatabaseConnection.getConnection(); if (connection == null) System.err.println("connection is null"); Statement statement = connection.createStatement();` (3) `if (connection == null) System.err.println("connection is null");` is only for debug. – life888888 Mar 18 '23 at 13:23
