I'm starting up a new project in Intellij IDEA and when I go to select a JDK all that shows up is JDK 16.0.1 and I need JDK 8 (already installed) So I click "add JDK..." I browse through my files and I'm only able to locate JDK 16. NOTE: JDK 8 is on my desktop
Multiple JDK environment variables cannot be configured on the same computer at the same time, but we can change the value to the corresponding JDK installation directory by modifying JAVA_HOME in the JDK environment variable:

JDK 1.8 is already installed in Windows 10 64 bit system. I am trying to create a scala project in Eclipse Scala IDE. Is says "Unbound classpath container: JRE System Library [JavaSE-1.8] in project.
While checking the Java build path-- Libraries-- JRE is coming outbound.
When I click to add JRE library, it has workspace default JRE (unbound)
While searching through preferences-- installed JRE--search. It gives no JREs.
If I try to add -- standard vm--directory ( JDK dir home). Ideally it should populate or detect all the jars but it doesn't detect.
I Tried running the application as 'Administrator' and it ran successfully.
Select your project and right click--> Build Path --> Configure Build Path -->Select Libraries--> Add Library-->JRE System Library--> Add the installed JRE here.
And if the JRE library is not getting selected, check the environment variables- JAVA_HOME and Path.
And to see if the java is correctly installed, try hitting this from CMD
java -version
I have multiple versions of Java installed on Windows 7 Home Premium 64-bit system. In order to install
Eclipse Java 2018-12
I have had to install the Java 11 JDK from the Oracle website. Despite setting JAVA_HOME and updating PATH in environment variables the only way to install and also run this version of Eclipse was to open a command prompt and
C:>set path=c:\program files\java\jdk11.0.1\bin
and then run Eclipse installer or installed instance.
The problem persists if I reboot my computer.
I want to be able to start eclipse by simply clicking on the desktop icon link.
The error I get when I try to run eclipse from the desktop link is:
Version 1.7.0_79 of the JVM is not suitable for this product. Version 1.8 out greater is required.
My C:\Program Files\Java\
contains folders
jdk1.0.7_79
jdk-11.0.1
jre7
I think I need all of these because I have some programs which I think retire java 7 so I don't think uninstalling java 7 is an option and don't think java 11 would replace it, or should I just get rid of java 7, is that what's causing the problem despite environment variables set correctly?
How can I fix this problem?
Thanks.
Add c:\program files\java\jdk11.0.1\bin to your Windows Environment PATH
The system was running C:\Windows\System32\javaw.exe
I fixed it by adding the Java 11 bin directory at the beginning of the Path environment variable instead of at the end of the string, separated by a semicolon.
First set JAVA_HOME then update path in environmental, refer screenshots attached.
Has someone tried setting up JDK 10 on IntelliJ in MacOS?
When trying to do so, I am getting message as
"the selected directory is not a valid home for JDK".
I have installed JDK 10 provided by oracle for MacOS
JDK intallation path on my machine is
/Library/Java/JavaVirtualMachines/jdk-10.0.1.jdk/Contents/Home
Proper support for Java 10 requires IntelliJ IDEA 2018.x version. IntelliJ IDEA 2017.x versions may not detect Java installation path properly.
Says on my eclipse "Unable to locate executable for jre1.8.0_77". It also deleted the JREs :( I tried to run my project and went into Windows and preferences to add it but I couldn't.
Go to Windows > Preferences.
Locate Java > Installed JREs. (Or simply type JREs in the search
box).
The screen will show the list of JREs.
Click on Add button, locate the new folder on your machine and select.
Remove the old JRE from the list.
Same Question has asked before and here's the Link - How to change default JRE for all Eclipse workspaces?
Maybe you updated Java version but your PC's environment variable for JRE is still referring to the old version of JRE. If you updated Java, update your environment variable also.
recently i encountered same issue,
this happened after i updated my jre
because of this there was mismatch with jdk and jre versions
uninstalled java and installed newer JDK (SE ) kit. https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
now both jdk and jre are same
I have netBeans 7.4 with openJDK 7 running on Ubuntu 14.04 x64 System.
I want to change the default "Source/Binary format" in java project setting to JDK 6 (I DO NOT WANT TO INSTALL OpenJDK 6 because I have openJDK 7 which is compatable).
Also in C++ Project, I want to change the default "Console Type" in the "Run" section of project settings from "Internal" which causes some problems to "Standard Output".
From the NetBeans doc:
Note: If a compatible JDK installation cannot be found, you might need to manually add a path to the JDK installation directory by doing the following:
Open the netbeans.conf file located in the netbeans/etc directory in a text editor.
Enter the location of a compatible JDK installation for the netbeans_jdkhome option. The default location in Windows is C:\Program Files\Java\jdk1.7.0_67 or similar.
Save the netbeans.conf file and run the executable file in the netbeans/bin directory.
https://netbeans.org/community/releases/80/install.html
Find the spot that needs changing by ctl-F JDK and tab down until you see where it is specifying the path. Hopefully your new JDK is located in the same folder and you only have to change the version number.
You should save a copy of the conf file as confold or something in case something goes wrong.
