from my PC I have the following
java -version
java version "1.6.0_05"
Java(TM) SE Runtime Environment (build 1.6.0_05-b13)
Java HotSpot(TM) Client VM (build 10.0-b19, mixed mode, sharing)
and under:
C:\Program Files\Java
I have only:
jre1.6.0_05
my question is that I need also directory jdk1.6.0
under C:\Program Files\Java
is it possible to install this java only for jdk1.6.0 and how?
From here download JDK and install on your pc.
Install the latest JDK from here.
Go to java.sun.com (or oracle.com now) and follow the download & installation instruction. In the title of your question you write you are using 32-bit WinXP - then you want this:
http://www.oracle.com/technetwork/java/javase/downloads/, select JDK, select Windows x86.
JDK is always coming with its own JRE. That does not mean you need to remove your JRE before installing JDK, you can keep it, if you wish.
btw 1.6.0_05 is quite old you should consider update.

Is PyCharm made using Java-Swing?
If it is, then how does it runs on a PC where JDK or JRE hasn't been set up yet?
When I look at my own PyCharm installation directory structure, I see a jre64 directory, which contains a Java installation.
And that seems to be a normal JRE:
$ ./pycharm-community-2018.2.4/jre64/bin/java -version
openjdk version "1.8.0_152-release"
OpenJDK Runtime Environment (build 1.8.0_152-release-1248-b8)
OpenJDK 64-Bit Server VM (build 25.152-b8, mixed mode)
So PyCharm comes with a Java distribution which it uses (even instead of an already available Java installation). Instead of my pre-installed and configured java 1.8.0_191, it uses the version it comes bundled with:
I need to install open JDK in my Windows 64-bit os. I have used ORACLE open JDK and downloaded from the below link: https://jdk.java.net/8/
While downloading I have selected Accept License Agreement and installed.
But, after the installation when I tried checking the version using command java -version it's showing like regular JDK.
Can anyone help me to get where I went wrong? Or is there any better vendor to install open JDK in windows. Thanks.
Amazon offers an open jdk for Windows (and other OS), but just for Java 8, 11 and 16.
You can download it from here: https://aws.amazon.com/es/corretto/
After installing it and running the java -version command, you will see something like this:
>java -version
openjdk version "1.8.0_242"
OpenJDK Runtime Environment Corretto-8.242.08.1 (build 1.8.0_242-b08)
OpenJDK 64-Bit Server VM Corretto-8.242.08.1 (build 25.242-b08, mixed mode)
You need to set your java version in environment of you machine and target your JDK8 bin folder, or any JDK that you want to have at your disposal when you run java -version.
The best way to do this is to use the builds from adoptopenjdk. They're very high quality and come in multiple variants for Windows ranging from zip files to MSI installers. Dead simple to install JDK 8, 11 or 15.
But, after the installation when I tried checking the version using command java -version it's showing like regular JDK.
This is because JAVA_HOME is pointing to your old JDK. You need to go to Control Panel and change the Environment Variables. Just do a search on Windows 10 for "Environment Variables" to easily find that configuration panel.
Azul Systems provides builds of OpenJDK and relative installers, for all OSes and JDK versions.
It also provides builds of the JDK with OpenJFX included.
The installers bind JAR files to be executed by Java on Windows.
Download from azul.com website
I know this is old but should anyone run across this in search of OpenJDK 8 go here

I am trying to install eclipse-cpp oxygen on macOS Sierra 10.12. While installing it i get an error that java version is not 1.8, while I had already installed latest JDK package. on terminal it shows java version as below
java version "1.6.0_65"
Java(TM) SE Runtime Environment (build 1.6.0_65-b14-468-11M4833)
Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-468, mixed mode)
Please suggest how can I upgrade my java version.
Apple don't provide a version of Java greater than Java 6. You must install Java 8 from the Oracle site.
In order to run Eclipse you must install the full JDK, the JRE download is not enough as it does not include the java executable.
The Oracle site is here
You can install Java8 from here.
http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
make sure to check the latest binaries of java and javac in PATH. You can override the old java binaries in path.
There is something going wrong with my java configuration and it is really bugging me. I am using IntelliJ IDEA and after downloading and installing java 8 I tried to configure my project to use that SDK but I could only locate version 1.6 under /Library/Java/JavaVirtualMachines/. I am new to OS X and I am really confused with the paths.
Looking on my Java control panel I can see I got installed Java 8 but after running java -version on the terminal I get 1.6.0_65.
And the which java gives back /usr/bin/java.
Please help I am completely lost
Here is an example with several Java versions installed side-by-side ...
ls /Library/Java/JavaVirtualMachines/
jdk1.7.0_25.jdk jdk1.7.0_72.jdk jdk1.8.0_05.jdk jdk1.8.0_25.jdk
User can edit ~/.profile to point explicitly at one
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_72.jdk/Contents/Home
export PATH=$JAVA_HOME/bin:$PATH
And here is result ...
java -version
java version "1.7.0_72"
Java(TM) SE Runtime Environment (build 1.7.0_72-b14)
Java HotSpot(TM) 64-Bit Server VM (build 24.72-b04, mixed mode)
Well something was wrong with the installation. I completely removed the other versions (not 1.6) and reinstalled 1.8 using the default path (as there is no option to change it during installation. Now IntelliJ can see JDK 1.8
Thanks for the help anyway
I just tried to run Eclipse on a Mac Book Pro running OSX Mavericks. I've downloaded both, the 32 and the 64 bit version. Both end up in following Notification:
Version 1.6.0_65 of the JVM is not suitable for this product.
Version: 1.7 or greater is required.
I know that the question was already asked, but my Eclipse won't event start with the 64-bit version, which was the answer for a smiliar question. So I checked the version of my installed Java by running
java -version
In the terminal. The output really confirmed, that version 1.6.0_65 was installed. Here's the output:
java version "1.6.0_65"
Java(TM) SE Runtime Environment (build 1.6.0_65-b14-462-11M4609)
Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-462, mixed mode)
Now the problem is that when launching the Java Control panel, it says, that Java 7 Update 67 is installed, and there are no updates.
So where's my problem, how get I get Eclipse to run?
You can modify the eclipse.ini and add the path to your JDK7
For versions of Mac OS X 10.7+ the location has changed to
-vm
/Library/Java/JavaVirtualMachines/<''jdk_name_ver''>/Contents/Home/...
To be safer, determine the location for the JDK you intend to use via the utility /usr/libexec/java_home and put this value with .../bin/java appended into the eclipse.ini file.
See "How to install JRE 1.7 on Mac OS X and use it with Eclipse?"
I installed JDK, "Java SE Development Kit 8u101", in addition to JRE and eclipse started to work fine.
