+
+Based on this tutorial the following classes were created.
+https://www.tutorialspoint.com/postgresql/postgresql_java.htm
+
+In order to create the table, run the PostgresCreate.
+Once the table has been created, one could insert data
+and subsequently select it by running the other java
+classes.
+
+Run docker-compose up first before running the java classes.
+Note: the postgres database resides in docker.
