VSCode says I don't have Java 11 or later even after installing jdk13, setting up java.configuration.runtimes, java.home and JAVA_HOME and path

I installed the default java extensions, downloaded jdk-13.0.2 windows installer, updated the path and JAVA_HOME in the environment variables. After searching for answers, I added the settings in VSCode for java.configuration.runtimes and java.home. After all that, when I try to run my java file in VSCode, it gives me the message "Java 11 or more recent is required to run the Java extension. Please download and install a recent JDK... Source: Debugger for Java (Extension)". I'm not sure what I'm missing or what I did wrong. I attached a screenshot of the VSCode settings.

If you didn't add java to Environment Path, java.exe couldn't be recognized and used except under the java installation directory, and that's why the java extension think you didn't install the required JDK.
Add JAVA to PATH. You can refer to PATH IN The Java™ Tutorials
Press Ctrl+Shift+` in VS Code to open the integrated Terminal,
then run java --version to check if it's the right one;
Install Java Extension Pack in VS Code Extension Marketplace, which includes necessary extensions you need during development.

It seems restarting my computer took care of it. I verified that java was working outside of VS Code but VS Code wasn't wanting to work with java. No changes were made but when I reopened the project it works.

java jre jdk setup using android bundled jre

There are many similar questions but mine is different so please read an entire question before nailing down the new.
Bundled JAVA jdk is automatically installed with Android Studio version 4.0.1. Everything I type java -version on my CMD then I get following message
C:\Users\OceanicBlue>java -version
'java' is not recognized as an internal or external command,
This is because JAVA_HOME is not setup so I tried following inside Environment Variables->System Variables in Windows 10 Machine but no luck. The problem is persistent.
JAVA_HOME -> C:\Program Files\Android\Android Studio\jre\
JAVA_HOME -> C:\Program Files\Android\Android Studio\jre\bin
JAVA_HOME -> C:\Program Files\Android\Android Studio\jre\jre\bin
JAVA_HOME -> %JAVA_HOME%\bin
Can I use Android's bundled JDK for JAVA_HOME? If not then which version should I download. Oracle forces you to register to use their JDK11. I refuse to give them my personal information to use something free. Also I don't want unnecessary extra versions of JAVA installed on my machine. Eventually they will cause problems.
What exactly am I trying to do? I am trying to compile Java programs using Command line. Android installed JDK for me so why not use it? No I am not able to compile a java project using the terminal screen inside Android Studio.

This is because JAVA_HOME is not setup
That's not what's happening. JAVA_HOME is not voodoo magic, the windows shell does not have some sort of built in knowledge. Commands entered are executed by scanning every entry in the PATH environment variable for java.exe, java.com, or java.bat. None are available. If you really want the java.exe found in C:\Program Files\Android\Android Studio\jre\bin to be used when you type 'java' on the command line (which will not magically make javac work at all, which is why I doubt this is actually want), then add that directory to the PATH variable. JAVA_HOME is mostly useless; a select few dated tools look at it sometimes and fail if it is not there; more modern tools may still look at it but also scan other places, such as the path or windows registry.
Furthermore, that's.. clearly not a bundled JDK, that's a bundled JRE, which can't be used for compiling. It does hava java.exe, but you can't use that to compile things. By nature of being a JRE, it is also obsolete/outdated (JREs are no longer part of how java is distributed; java8 is the last version with a JRE).
Note that javac in general is relatively useless when dealing with android; android does not run class files.

I am using Android Studio 4.1.1
What exactly am I trying to do? I am trying to compile Java programs using Command line. Android installed JDK for me so why not use it?
First of all, it is just the bundled JRE. Its is not JDK.
But, I was able to compile and run my test.java by adding two new entries in my environment variables.
C:\Program Files\Android\Android Studio\jre\jre\bin
C:\Program Files\Android\Android Studio\jre\bin
NB: I have never installed JDK before. I just used the JRE binaries present in jre/bin/ present within Android Studio folder
See the attached image.
I think you should recheck your environment variable or else try to get Android Studio latest release.

Cordova android run/build Error - Requirements check failed for JDK 1.8

I have built my cordova app and getting "Requirements check failed for JDK 1.8" error message.
Uninstalling all java and installing jdk 1.8 not solved my problem.
D:\xampp\htdocs\aware>cordova run android
Android Studio project detected
ANDROID_HOME=C:\Users\Baha\AppData\Local\Android\Sdk
JAVA_HOME=C:\Program Files\Java\jdk1.8.0_221
Requirements check failed for JDK 1.8
ScreenShots:

You might have installed more than one Java (binaries) on your system. First of all, check this, by executing where java command in your cmd.exe (command line).
Most likely, you will see more than one java.exe installed, and if so, this may be the reason, despite installing new Java, your system still provides one more other version of it;
Even if you have set your %JAVA_HOME% environment variable accordingly, there might be another java.exe available in your environment, either because of having some other Java binaries' bin folder added in the System variables' (under Environment Variables) Path variable, or because of having it at some other place, which is also available through any other environment variable (for instance: System32 on Windows).
Check where java and see your Path environment variable under the System Variables.

My problem solved partially, I have changed the path and try to build with vs code, it works, but phpstorm still not build my app.

Android Device Monitor not found JDK Path

I'm using Arch Linux with Gnome.
I open Android Studio by the desktop item. The code editor works fine, the device manager starts correctly and the app run like a charm, but when I try to open the Device Monitor, I get this error:
A Java Runtime Environment (JRE) or Java Development Kit (JDK)
must be available in order to run Monitor. No Java virtual machine
was found after searching the following locations:
/home/grams/Android/Sdk/tools/lib/monitor-x86_64/jre/bin/java
java in your current PATH
When i run the android studion from command line, the Device Monitor works.
Here is the .desktop content
#!/usr/bin/env xdg-open
[Desktop Entry]
Version=1.0
Type=Application
Terminal=false
Icon[en_US]=/home/grams/android-studio/bin/studio.png
Name[en_US]=Android Studio
Exec=/home/grams/android-studio/bin/studio.sh
Comment[en_US]=Android Studio IDE
Name=Android Studio
Comment=Android Studio IDE
Icon=/home/grams/android-studio/bin/studio.png
My JRE and JDK variables are being added on /etc/profile.
When i run Android Studio on the command line, this error not occurs. Maybe it is a problem with Gnome launcher ?

Newest Android Studio Bundle comes with its own JRE (under <ANDROID_STUDIO>/jre and this is the recommended JRE to work with (look at File / Project Structure / SDK Location).
Likewise, a simple option is to create a symbolic link under the monitor tools to keep JRE in line with Android Studio even getting an update.
For MAC or Linux:
#ln -s <ANDROID_STUDIO>/jre <SDK>/tools/lib/monitor-x86_64/jre
32 bits:
#ln -s <ANDROID_STUDIO>/jre <SDK>/tools/lib/monitor-x86/jre
Then the ddms monitor works for both ways: from Studio IDE (Tools / Android / ADM) or command line (<SDK>tools/./monitor)

Define your environment variables in the initialization file for your login shell: most likely .profile or .bash_profile, depending on your setup. Something like:
export JAVA_HOME="/usr/lib/jdk1.8.0_05"
export PATH=$PATH:$JAVA_HOME
Read more at: where should i manually install JDK8? and JDK installation on Archlinux

Please add the location of the folder containing javaw.exe to the System PATH Environment Variable:
e.g PATH = "C:\Program Files\Java\jdk1.8.0_112\bin"

Make Sure that the variables deceleration naming convention is according to the rules, and the Android Studio is searching by the names, that are predefined.
As in Windows, the Variable that contains JDK path should named: JAVA_HOME
Explore the rules.

How to make Eclipse search for JDK on another drive

So I've been getting this error when trying to start Eclipse:
"No java virtual env found after searching the follow locations:
/absolute/path/to/jre6/bin"
I checked the control panel and I got JDK (Update 21 / 64-bit) installed.
However, JDK is installed is installed on my primary drive (the sdd with Windows on) whereas Eclipse is unzipped and executed from my secondary hard drive.
How to I tell eclipse to find Java on my c-drive instead of the d-drive where it's located?
Thanks in advance!

I would suggest you uninstall all versions of Java you have installed and then installed the one you want to use.
Another option is to tell eclipse which Java to use. For example: eclipse -vm c:\path\to\jre\bin\javaw

Locate the eclipse.ini file and ensure that the variable -vm is correct (
FAQ How do I run eclipse):
If a JVM is installed in the eclipse/jre directory, Eclipse will use it; otherwise the launcher will consult the eclipse.ini file and the system path variable. Eclipse DOES NOT consult the JAVA_HOME environment variable.
