  • Learnt about Refactor, which can rename a variable and in all the classes that may link to it rather than just a find/Replace 
  • Learnt about using objects in classes, such as a engine in a car class
  • learnt about using the .getObject method to access the objects methods e.g. .getObject().setValue()
  • Learnt that you don't declare a constant object for your class because all the Instances of your class will refer to the same object, so you use new Object() instead.
