Java has also been used for emerging technologies like robotics, but the two uses above are the main ones. It has been estimated that around 80% of the worldвЂ™s largest websites use back-end web apps built with Java. This has led to mass adoption by back-end web developers building web apps for large websites. Java is extremely scalable and relatively easy to maintain.

If you have no reason to choose a particular vendor, I suggest using AdoptOpenJDK, a cooperative effort supported by many in the Java community including most (if not all) of these vendors listed here.ДЇor more info, read the important posting: Java Is Still Free.Have you ever wondered which online learning platforms are the best for your career? See & compare TOP online learning platforms side by side Android App DevelopmentДЄlthough some programming teams are starting to use other languages, pretty much every single app ever made for Android operating systems is built on Java. All but the last two of these vendors likely provide an installer app for your Mac. Here is a flowchart I made to help explain the various implementations. Meanwhile the IDE continues to run itself using its own internally-bundled JVM. Within your IDE settings, project settings, and build-tool settings (Maven, Gradle, etc.), you can tell the IDE what external JVM to use to run your app.

But you likely will want to download and install a JVM of a version (and possibly vendor) akin to what will be used in production. This JVM could be used to run your app in development, as I recall. This internal JVM is used to run the IDE itself.

So your downloaded JVM would not actually be running your IDE. IDE uses its own JVMД«e aware that some IDEs such as IntelliJ come bundled with their own Java implementation. вЂ¦to verify your newly installed Java implementation. No additional configuration needed.ДЄfter the installer is done, in a terminal app run: java -version I have always found that after using an installer to install a Java implementation on macOS, the correct paths are already set for me. Obviously, be very careful with changing your path, you don't want other programs to break, so make sure you simply add the desired JDK path in front of your original variable, so that the only related program, java, has a change.

Most likely you may want to add the path to your desired JDK in the beginning of your existing $PATH variable. The first command adds to the end of your path, the second adds to the beginning. In order to amend your path you will add a command similar to the following to one of the bash profile files for your system: export PATH=$PATH:/ In order to view your current path, you can run echo $PATH Quite simply, if the version you do NOT want is the one that appears when you run java -v or which java then you must add the path to the desired JDK to your $PATH as mentioned. There is a convention you can read about regarding where you should do it. (Note these are the files for my system, macOS, but the profile files may be different for Linux installations, I simply do not know).

If you have multiple versions installed, you can amend your $PATH variable inside either. If you would like to view all Java JDK versions that you have installed, you can run the first command mentioned with the -V (verbose) flag, and it will list the paths to all you have installed. Which will show you the current version of the first JDK that your path encounters. This will return the default Java jdk you currently have installed. The easiest way to determine what java installations you currently have installed is by running: /usr/libexec/java_home
