I have been trying into Java for doable future initiatives. Write As soon as Run Anyplace (WORA) is the claimed advantage of utilizing Java, and my aim is to try this for any platform.
Instance: write a program as soon as in Java so it will possibly run on Home windows, Mac, Linux (deb, yum, and so on), and iOS, and Android. I do not actually care about freeBSD, or every other extra obscure issues. The top consequence ought to make the GUI on all platforms look the identical, and buttons to carry out the identical features.
The issue is that I’ve seen you possibly can’t run regular Java applications on Android, and as an alternative you want one thing like Kotlin in the event you wished it to run there, or do some further steps that convert the usual Java into Kotlin… And so far as I am conscious, Kotlin technically is Java, however fewer of it is authentic libraries are included, and the syntax is slightly totally different.
I do know there are various Java Growth Kits (JDK’s) together with the paid one by Oracle, however as a consequence of what I stated about Kotlin above, it makes me assume every JDK goes to be watered down with fewer options to some extent.
Instance: As an instance I select to make use of Amazon’s Corretto for my JDK. Their web site says it is appropriate with Oracle’s Java SE normal model… So I make a plain Java program on a desktop Linux machine with it, and it really works superb. It additionally works superb on Home windows 11. Then I attempt to put it on an Android, however it fails: the GUI is all flawed, it does not ship requests, do calculations correctly, and so on.
Since plain Java cannot run on an Android in keeping with the article above (with out doing further steps): is Java actually WORA, or is there one thing I am lacking?
How would you go round this drawback? As a result of to me, it seems like a local language to every platform remains to be the best choice for pace of this system, and so on, regardless that a separate code base for every platform is required (Swift for iOS, Kotlin for Android, and so on).
