Good evening, I'm just starting to study computer science and today we talked about classes, objects and methods. If I understand correctly, classes are like blueprints. From these, objects emerge, which in turn have methods. For example: Class: Car -> Object: VW or Object: BMW or did I misunderstand that? and what is the constructor…
Hi guys, In the picture you can see 4 variables, but I can't tell anything about the data type of the first one…is it even a variable
For example, a person is instantiated in the main program. I want to insert the citizenship properties "German" and "Dutch" into a Person class in a string hash set. How do I combine this in a constructor?
What is the difference between super. super() this. this() in Java and how is this applied to program analysis? Thanks.
