      First project is 'figures' that corresponds with Section 1.2 and 1.3 of the video.

      That's very kind - thank you! I'm currently recording lectures on the fundamentals of Java (which relate to the initial chapters of BlueJ), but hoping to produce additional videos on the BlueJ chapters in 2022.

    Hello mate, I have a project for school, but I don't know how to link two classes together, like to have the little arrow between the two classes.

    HI, when i download the zipfolder from the link you´ve pinned down an i try to open them in blueJ, i´m just getting a blank page without all the examples. but i can see them in the folder. also when i try to open the note pad to see how the codes are written, i can´t open them, can you help me with that?

    Easy to follow and great explanation. Why is that in general, university lectures are not able to explain these concepts in a way that most of the students can understand? I am sure lecturers are watching these videos as they use as a reference. Would be curious about their point of view...

    • @NicholasDayPhD

      This is a very good question... I think some experienced lecturers or professionals forget what it is like to learn the subject for the first time, because it is so familiar to them... What seems clear to us, is not often clear to a student who is new to the subject... It's very useful to be reminded of this - thanks for your question!

    Hi, I can't find the void makeInvisible method. It's not included in my BlueJ program. Any ideas?

      Hi Jojo, have you opened the right BlueJ project that corresponds with this exercise? The method should be given to you by default in the first project.

      @@jojoverdejo It should be provided for you, as the other methods are. Can you see other methods such as makeVisible(), moveDown(), moveUp() etc in the list when you right click on an object? If not, you may not be in the right project... Check you've loaded the 'figures' project.

    I downloaded the FIGURES project but its a zip file and idk what to do now can u guide pls

    • @NicholasDayPhD
      @NicholasDayPhD  2 роки тому +1

      Hello there, make sure to 'unzip' or 'extract' the files from the downloaded zip folder. On a Windows device it should be a menu option on the top right in the 'ribbon'. Or alternatively, right click on the zip folder itself and there should be an option in the menu to extract or unzip. Then, in the extracted folder, make sure you open the 'package' file - should have the BlueJ icon if you've installed BlueJ. That should then load the 'figures' project in the BlueJ IDE with the associated java files.
