SQL Developer is a 'client' tool. It is pretty much worthless without a database to connect to. You can't execute SQL statements without a database. The database can be either on your local machine (where you have installed SQL Dev) or on a remote machine. To get a database on your own machine, you will need to download Oracle Database, install it, and create a database. Be sure to read the installation guide for installation prereqs, including certified operating systems.
