Java version confusion need to set JAVA_HOME to Java11

I'm not able to set Java11 to my JAVA_HOME env
I installed Java through home brew, how can I switch the version?
I needed to intall this java zulu to run Salesforce Data loader.

Need to source java-1.8.0-openjdk-amd64 specifically and install?

App throwing error at startup looking specifically for java-1.8.0-openjdk-amd64. Environment is Ubuntu1604. Java java-8-openjdk-i386 is already installed , but need the amd64 and then use it as an alternate. Where can I source amd64 tar file ? Have ran "sudo apt-get install openjdk-8-jdk". thx
2/6/21 current status - have not being able to install Java 8 AMD64.
Hi there, I tried :
sudo tar xvf jdk-8u291-linux-x64.tar.gz --directory /usr/lib/jvm/
and this installed to /usr/lib/jvm/jdk1.8.0_291.
However I was expecting /usr/lib/jvm/java-1.8.0-openjdk-amd64 folder structure.
Whats currently installed is:

How can I complete the install. The app I'm trying to use is looking for :

Answering your question as-is - you can find links to all jdk implementations on jdk.dev . But you'll have to extract jdk and add bin directory to PATH by yourself
As for updating alternatives it's a question for askubuntu.com, but I believe, that you should do install before updating.
sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.8.0_291/bin/java" 1

Cordova/Android not finding JDK on OSX and PATH/JAVA_HOME correct

So cordova requirements is still failing for Android after trying and verifying all paths, versions and suggestions. It's on OSX 10.10.5 and a clean install of Android SDKs/Studio and cordova. Have tried Apple recommended (export JAVA_HOME=/usr/libexec/java_home -v 1.8) and direct paths with same failed result. Have verified both java/javac are in the bin directory of the JDK path.

The only thing in digging through the source for cordova-android on gitHub is in check_reqs.js, the error message is:
Failed to run "javac -version", make sure that you have a JDK installed.
rather than as it currently reports:
Failed to run "java -version", make sure that you have a JDK installed.
Any help greatly appreciated.
Rob

So a number of issues. check_reqs.js is where the platform/environment checks are done (app/platforms/android/cordova/lib/). The call to forgivingWhichSync('javac') on line 98 was returning the non-JDK link (as it was using Current, not CurrentJDK):
/System/Library/Frameworks/JavaVM.framework/Versions/A/Commands/javac
By repointing the Current symlink in /System/Library/Frameworks/JavaVM.framework/Versions/ to CurrentJDK it fixed this first issue:
lrwxr-xr-x 1 root wheel 10 21 Jul 12:03 Current -> CurrentJDK
lrwxr-xr-x 1 root wheel 59 21 Jul 12:06 CurrentJDK -> /Library/Java/JavaVirtualMachines/jdk1.8.0_102.jdk/Contents
The next issue was a problem with the tryCommand method testing javac. As correctly noted, javac -version returns the information in stderr. The issue (at least on OSX) is that the call to child_process.exec on line 44 also returns information in err:
Error: Command failed: /bin/sh -c javac -version
javac 1.8.0_102
javac: no source files

where possible options include:

-nowarn Generate no warnings

-target <release> Generate class files for specific VM version
-version Version information
-help Print a synopsis of standard options

-J<flag> Pass <flag> directly to the runtime system
The handling of the callback to this child_process.exec always triggered an error if err was non null:
if (err) d.reject(new CordovaError(errMsg));
changing this to only trigger this error if the catchStderr flag was not set now correctly handles the test for javac:
if (err && !catchStderr) d.reject(new CordovaError(errMsg));
and now success:
sh-3.2# cordova requirements
Requirements check results for android:

Unfortunately need to edit check_reqs.js for each project when you cordova platform add android but at least it's now finding everything.

Everything worked perfectly when I did the installation with Cordova version 7 and JDK 1.8u131 on OSX. Nothing had to be changed or configured. Possibly the older versions of Cordova had issues.

jar: error while loading shared libraries: libjli.so [How to manually install Java 6]

I'm running into this error when I'm building android 2.3 from source code on Ubuntu 10.04. I am suspecting it is an issue with a path or something along those lines but cannot figure it out. I have seen similar people have this issue but I haven't found any solution that works for me. I included some information about my environment, any help would be appreciated(if you know my path's are correct then even that would be beneficial as I could start look into other possible sources of error). Thanks.
java -version should indicate the installation was successful:

I'm posting my solution on here in case anyone else runs into a similar problem and stumbles across this. I simply re-installed my OS, ran the steps again, and everything worked perfectly fine this time. I must have caused some sort of error on my machine as I ran the same exact steps too. Here is what I did to manually install Java 6 on a clean machine:
Install Java 6(.bin format) from the Oracle website
Give it executable permissons and execute it
Add a jvm folder to usr/lib/
Move your Java 6 folder to usr/lib/jvm
Link java/javaws/javac to usr/bin using the ln -s command
Add your Java6 and Java/bin location to your path. For me its:
export JAVA_HOME=usr/lib/jvm/jdk1.6.0_45
export PATH=/usr/bin:$JAVA_HOME/bin

Mac OSX Java Terminal version incorrect

Ok, I'm a bit new to Macs and OSX, but I picked one up so that I can do some troubleshooting on my Java programs with one since the company I work for uses a combination of OSX and Windows machines. The problem I'm running into is, when I install Java 7 from Oracle's website, it updates the preferences menu and appears to execute .jar files correctly when double-clicking them, but the terminal window's version is still 1.6.0_43 and running the same .jar file from the terminal results in runtime errors due to the older version.
When I navigate to /Library/Java/JavaVirtualMachines/ I'm presented with an empty folder. From what I've seen in other articles, this is where the Java 1.7.0's version folder should be. Any idea what's going on? How can I get the terminal to use the correct version of Java?

JDK
On Mac OS, /usr/bin/java and friends are stubs that delegate to the real JDK commands. These stubs respect the setting of your JAVA_HOME environment variable, but for this to work you need to install the JDK (from http://www.oracle.com/technetwork/java/javase/downloads/index.html) as opposed to the JRE (from http://java.com).
The JDK installs into /Library/Java/JavaVirtualMachines/jdk1.7.0_NN.jdk (for whatever value of NN), so set your JAVA_HOME environment variable to /Library/Java/JavaVirtualMachines/jdk1.7.0_NN.jdk/Contents/Home to make /usr/bin/java use 1.7. You can switch back to 1.6 simply by pointing your JAVA_HOME to /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home instead. You can use the /usr/libexec/java_home tool to find the right value automatically, for example to make /usr/bin/java use Java 7 you can do
export JAVA_HOME=`/usr/libexec/java_home -v '1.7*'`
and to make it use Java 6 you can do
export JAVA_HOME=`/usr/libexec/java_home -v '1.6*'`
The same applies to Java 8 (using -v '1.8*'). This will pick up the latest installed JDK for the relevant major version, you don't need to remember to change the NN by hand when you install an update.
JRE
If you want to run the 1.7 or 1.8 JRE from the command line, it can be found in /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java. This is a fixed path and you can only have one "public" JRE installed at any given time.
$ /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java -version
java version "1.7.0_13"
Java(TM) SE Runtime Environment (build 1.7.0_13-b20)
Java HotSpot(TM) 64-Bit Server VM (build 23.7-b01, mixed mode)
You could use a shell alias in your .bashrc
alias java_jre='/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java'

The issue is that Oracle's JRE installation does not change the /usr/bin/java executable. If you want to use this Java you have to use the path under /Library (need to find what this is I have JDK install so could be different)
As per Oracle's JRE installation document
Installing a JRE from Oracle will not update java -version symlinks or
add java to your path. To be able to do this, you need to install the
JDK.
The Oracle JDK does change /usr/bin/java to point to the Java 7 executable. If you are doing development then you should use this as it includes more than the JRE.
The Oracle install FAQ says
Q: Should I install the JRE or the JDK?
A: If you plan to run Java applications, install the Java Runtime
Environment (JRE). The JRE is also referred to as Oracle Java. Once
you have installed the JRE, you can launch Java applets and
applications by double-clicking JAR files, JNLP files, and via the
browser. Note that 32-bit browsers, such as Firefox in 32-bit mode,
and Chrome, are not supported by the JRE.
If you plan to write Java applications, install the Java Development
Kit (JDK).

First, did you Quit the Console and open it again so it has chances of taking the changes in the PATH variable ?
If you've already done this, then check which the default version of your Java is:
dwilches# ~$ cd /System/Library/Frameworks/JavaVM.framework/Versions/
dwilches# Versions$ ls -l
lrwxr-xr-x 1 root wheel 59 Mar 19 10:07 CurrentJDK -> /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents
lrwxr-xr-x 1 root wheel 10 Mar 19 10:07 1.6.0 -> CurrentJDK
lrwxr-xr-x 1 root wheel 10 Mar 19 10:07 1.6 -> CurrentJDK
lrwxr-xr-x 1 root wheel 10 Mar 19 10:07 1.5.0 -> CurrentJDK
lrwxr-xr-x 1 root wheel 10 Mar 19 10:07 1.5 -> CurrentJDK
lrwxr-xr-x 1 root wheel 10 Mar 19 10:07 1.4.2 -> CurrentJDK
lrwxr-xr-x 1 root wheel 10 Mar 19 10:07 1.4 -> CurrentJDK
lrwxr-xr-x 1 root wheel 1 Mar 19 10:08 Current -> A
drwxr-xr-x 8 root wheel 272 Mar 25 10:03 A
Now, you can see that the "Current" version is "A" (that's my Java7). If I would like to change it to Java 1.6 then I could write:
dwilches# Versions$ sudo unlink Current
dwilches# Versions$ sudo ln -s 1.6 Current
And then:
dwilches# Versions$ java -version
java version "1.6.0_43"
Java(TM) SE Runtime Environment (build 1.6.0_43-b01-447-11M4203)
Java HotSpot(TM) 64-Bit Server VM (build 20.14-b01-447, mixed mode)
So you may use this to make "Current" point to your desired Java location.

Just like Ian said, but probably you want java7 to be called from .sh script, so you need a function instead of alias added to .bash_profile:
java7() {
/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java "$#"
}
export -f java7
