Many Spring and Spring Boot tutorials use Maven or Gradle. I suspect that Spring can be used with Ant and Ivy, do to have any hints/tutorials on how to best approach this?

What is the recommended process to move from Ant and Ivy to Maven or Gradle? Maybe you can point me in the general direction of some tutorials on this?

Welcome to CodeRanch Max.

Oracle and Acclaim and Pearson Vue do not provide physical copies of the Java 8 certification.
However you should have been given access to a web site which would allow you to download a PDF version of a certification document.
You could easily print this off and get it framed.

Now what you have a certification what's you next challenge?
Many people choose to get both their OCA and OCP certifications and then branch out from there.
You may want to look at some of the stories posted https://coderanch.com/wiki/659976/OCPJP-Wall-Fame to see how others have prepared for their OCP.
This could save you time, money and frustration.

IDEs are great for writing code especially production code.
You do not need to use an IDE, but they do tend to make things easier as they offer things like spell checking, syntax highlighting, debugging and more.
However you can use something like Windows Notepad to program Java (and many other languages) in.

meenal deshpande wrote:...and which is the best IDE

This depends on who you ask and what the purpose is. Everyone will have their own "best".
If you are more interested in Android programming then you may be more interested in Kotlin and as a result you would probably gravitate towards IntelliJ.
A rebranded version of IntelliJ is provided for free by Google and JetBrains for Android development. JetBrains are the ones who started the Kotlin language.

In the end @meenal, you will probably find that most Java IDEs have close to the same functionality especially if you extend them with plugins/addons.
So the question then becomes which IDE do you like to use and why?

Some companies may enforce and IDE and others may not.
Two of the most popular IDEs for Java are Eclipse and IntelliJ and it can be helpful to know how to use both of them.

Looks like we are going to need a bit more information in order to proceed such as:
  • Do you have a question about the code posted?
  • Does it compile?
  • Dose it run?
  • Does it run as expected?
  • What do you think the code should do?
  • Do you get any error messages? If so please provide them.
  • What Android version are you targeting (Lollipop, Marshmallow, Oreo, Pie, etc)?
  • What plat form are you targeting (phone, tablet, wareable)?

    First I would make sure that everything posted runs as expected.
    Next I would make sure that the unit tests are there, and if not then I'd add them.

    Now  that you have a copy of the project and all of the required unit test fire as expected you should try to see what is missing.
    For instance, is there a method which draws a card? If not you could add one.
    However if there is one, how does it do it? Does it use AWT, JavaFX, Swing, ASCII, etc?
    Ideally the project should support a render card interface and there should be more then one implementation of it.

    You can add what ever classes you want, but note that your code will be inspected and people may have questions/comments about your changes.
    There may be a changelog and a backlog, but then again those may not be there yet.

    Another thing you could do it go over the code to see if it make sense to you.
    If you have any questions regarding the code start a thread in the Corral and hopefully some people will join in and discuss them.

    Congratulations, here is a cow you have earned it.

    When you get a few moments please add yourself to the OCA Wall Of Fame https://coderanch.com/wiki/659980/Ocajp-Wall-Fame.
    By the way, what were you Enthuware scores?

    If your next challenge is the OCP exam then you may want to look at some of the sotries posted on the OCP Wall of Game https://coderanch.com/wiki/659976/OCPJP-Wall-Fame.
    This could save you frustration, time and money.

    I'm glad to see hat I'm not alone with my views on this matter.

    Yes Campbell, a touch interface would be allowed however I suspect that many of us use non touch interfaces most of the time unless you are talking about smart phones and tablets.

    Do you touch your screen/monitor, the glass part? Maybe with your finger when pointing something out? I'm not talking about smart phones or tablets add that is expected. Some people do, but I do not. It almost drives me crazy.
    Displays can be wrecked due to this. Maybe the screen isscratched or just gets dirty. A decent display can easily cost a couple of hundred dollars or more.
    There is a reason for line and column numbers, and your can use that when talking about code.

    Maybe I'm alone with this view this is just one of my personality traits?

    Congratulations, don't take this test again. I'm not even too sure if your would be allowed to, because you passed.
    I do suggest that you take your time, go over your notes, try out Enthuware and look at the stories on both https://coderanch.com/wiki/659980/Ocajp-Wall-Fame and https://coderanch.com/wiki/659976/OCPJP-Wall-Fame.

    Getting any certification in and of itself can be helpful. However not everyone treats certification the same way. If you have  many certifications and no work to show for it on GitHub (or some other site) or no practical experience then you chances of finding employment are greatly reduced.

    For many, the value in achieving your OCA/OCP is in the journey. Many OCA/OCP books teach you about some of the generality accepted coding practices and how many of the standard building blocks should/could work. Learning about interfaces, abstracts, inheritance, lambdas and more is a great way to start.

    If you are looking for other things you could do to get noticed then try to get involved in an open source project, there are many to choose from.
    I'm not too sure which card game you are making, but some members of CodeRanch are also making a card game as noted here https://coderanch.com/t/698891/open-source/September-Project-BlackJack.
    Personally I have not posted to the Ranch Corral for a few days, however I plan on add in a few thoughts in the next few days and maybe in the next week or so posting more code for discussion/feedback.

    It is hard to know if something could be done is better without looking at the existing code.
    Are you able to post your code to the site? Please format it using the code tags as explained here https://coderanch.com/wiki/659781/Code-Tags
