    With the water bottle, would you be able to set a scanner so they decide the amount and how much they drank?

    Here you created the object of one class into another class without using inheritance or anything? How is that possible? Is it allowed in c++ too to create object of one class into another just straight..

    Very useful videos. I knew a little from reading minecraft code but this is really helpful. Also for others, if you add
    System.out.println("Your remaining water level is: " + waterBottle.getWater() + " liters"); this will show liters after the water level is displayed. I was playing around with it to see how you could add text after the object. Cheers.

    you are awesome at these tutorial. One thing that would work for me as a leaner, keep mentioning which ones are a parameter, instantiate, variables, etc.. you great!

    Best explanation on what object oriented programming is. Thank you so much for your genius water bottle example. I appreciate it.

  25. DreadTheZombieZ June 11, 2017 at 1:58 am - Reply

    Didn’t watch it all yet so I dunno if he said this butttttt you can do tWater += amount; its the same as tWater = tWater + amount;
    for people who watch this in the future 😀

    will teacher just for you to know a constructor is used to initialize objects and you defined a default constructor which you do not need to cuz every java program have a default constructor hidden and defined.

    Must allow the user to find the total voltage of batteries when installed as a single,double, or quadruple set.
    Must be able to set the voltage to calculate
    Must input the kind of battery (String name)
