Properties File • Cre a te a new f ile in your resource's directory (usu a lly src/m a in/resources in a M a ven project) a nd n a me it for ex a mple con f ig.properties (or a ny n a me you prefer). • Add the properties you need in this f ile. 31 

Properties 32 

Properties This f ile should not be committed to your version control system if it cont a ins sensitive inform a tion like API keys. Advice: • Cre a te a copy of your con f ig.properties f ile a nd n a me it con f ig.s a mple.properties. Repl a ce the sensitive d a t a like the API key with pl a ceholder v a lues. • Add con f ig.properties to your .gitignore f ile. This will prevent the a ctu a l properties f ile from being tr a cked by Git. • Commit the con f ig.s a mple.properties f ile to your repository. This will provide a templ a te for other developers to know wh a t keys/v a lues a re expected in the a ctu a l con f ig.properties f ile. 33
