Why is this(name , 0); necessary in public Machine(String Name){..}??
It has two constructors by? the end of the video; one of them takes only a string, the other requires a string and a number.
new Machine();
in the main method? We wouldn't ever be able to refer to this object again, so why? would we do this?
Sometimes you can create classes where large parts of the program run in the constructor of a class like this; then it makes sense. For example, a desktop program might say "new MainFrame()"; this might create a main window, and the constructor might add lots of panels and widgets to it. So you just need? to create the main window and never have to refer to it again.
Ok,? that helps. It seems like I wouldn't have a way to get a handle on those panels, windows and widgets without going through a specific MainFrame object later, like myMainFrame:
MainFrame myMainFrame = new MainFrame();
... but I'm sure this will all make sense later. Thanks again! I'm really liking the series.
It's a pleasure :) The buttons and stuff that you add in the constructor of your window class would have their own methods that would then? be invoked automatically when they're clicked, so for that reason you wouldn't necessarily need to refer to the main window class again.
This is? a very crucial topic and its used daily in my production code.
machine arnie? haha
Yes I think you understand? it correctly. It's setting the private String name to Chalky.
in machine3 "chalky" makes private string name =chalky? :this.name=name makes machine string name=chalky
is this right please
