How to install Java JDK 8 in windows?
Do I require admin right?
What Happens if i just copy JDK from one system to another with admin rights.
Steps To Do that:
STEP1 : Install JAVA JDK 8 in personal system where you have admin rights.
STEP2 : Copy the install JDK folder to system where you dont have admin rights.
STEP3: Go to Start Menu and Search environment and click on "Edit environment variable for your account"
STEP4: Now Click on Add in User Variables and add below local environment variables.
A. JAVA_HOME
B. PATH
C. CLASSPATH
It works absolutely fine. I have been using JDK like this for almost a year.
I found similar post but it has different technique.

Error Launching Idea. Failed to load JVM DLL C:\Program Files\Java\jdk1.8.0_112

I have got myself a new laptop Asus it runs on Windows 10 x64.
I have downloaded on this laptop java 10.0.2 and the latest version of intellij.
I did open once the intellij yesterday but today I wanted to open it again and im keep getting that error
I tried to google it out and I entered my variable environment and I did define that JAVA_HOME but it did nothing...
I would appreciate some help.
there are to chances causing this:
Wrong JDK - check whether you have downloaded the JDK for x64, and if not download it and install the correct one. JDK download site click here
Environmental variable is not set properly - Here is the guideline to set Environmental variables click here
To permanently run as administrator follow these steps:
Navigate to the program folder of the program you want to run. For example, C:\Program Files\Adobe\Acrobat 8.0\Acrobat.
Right-click the program icon (the .exe file).
Choose Properties.
On the Compatibility tab, select the Run This Program As An Administrator option.
Click OK.
We've got a customer who runs its Windows 7 installations with user profiles stored on a Windows Server on the intranet (it's called "terminal server environment" or something like that I think...).
Now I have some problems in Java regarding these "external" user profiles.
I am storing some settings in a folder in the users home folder (Windows: C:\Users\username\, Mac: /Users/username/). Because the app is cross-platform I don't use the windows environment variable %USERPROFILE% in Jave but the native Java property user.home.
However, this is what windows CMD says for the %USERPROFILE% variable:
>echo %USERPROFILE%
C:\Users\vvw\
And this is what I get in Java:
>System.getProperty("user.home")
C:\windows\system32\config\systemprofile\
Why does the Java property user.home defaults to this strange directory?
And what would be the best way to get to correct user home dir in Java for both Mac and Windows?
Update:
Re-installing java and rebooting helped. However, it's good to know that this is also tracked as a bug in the Java Bug Database and this will be fixed in Java 8.
Read this article, someone there has the same problem.
Because you didn't say, that there are no problems on the mac, execute your code on other windows machines. Maybe something is wrong with your developer machine.
The directory C:\windows\system32\config\systemprofile\ looks like the user directory of the user SYSTEM, but I'm not sure. That could mean, that java is running under the user SYSTEM.

Eclipse - no Java (JRE) / (JDK) … no virtual machine
I installed the Android SDK and it mentioned that I should download eclipse as well, but when I download and try to run the eclipse.exe, I recieve a message stating "A Java Runtime Environment or Java development kit must be available in order to run eclipse....". I do have JDK, which is the only way the Android SDK would have been installed. Any suggestions?
Set your computer's PATH (environmental variable) to the bin folder of your JDK. Here's how:
Windows 7-Start->Control Panel->System and Security->System->Advanced system settings(panel on the left)->Advanced->Environmental Variables(bottom). Under System Variables find PATH. Select it and hit edit. Point it to the bin of the jdk. If that doesn't work try adding a JAVA_HOME variable to the User variables ( hit new than enter JAVA_HOME for name and the value is the bin folder again). Hopefully that should do it. I feel your pain the same thing happened to me when I first started.

Eclipse - no Java (JRE) / (JDK) … no virtual machine
I am trying to get Eclipse Indigo to re-Start on my computer - i have run it before with no problems but now i getting error like this;
A java Runtime Environment (JRE) or Java Development kit (JDK) must be available in order to run Eclipse. No Java virtual machine was found after searching the following locations: C:\eclipse\jre\javaw.exe javaw.exe in your current PATH
How can i rectify this problem?
You can specify JVM in eclipse.ini file at the Eclipse root folder, like this:
-vm
C:\java\jdk1.6.0_24\bin\javaw.exe
This line must be placed before -vmargs options.
and for Linux
-vm
/..java address../bin/java
Try following:
Look at your filesystem and make sure a java instance is installed in the mentioned path
Open Eclipse and check the general preferences from Eclipse. Under 'Java' -> 'Installed JREs' must be a specified JDK configured.
Next, open the general preferences 'Java' -> 'Build Path' -> 'classpath Variables' and look is there the jdk instance mentioned. If not, open dthe control settings from windows and add the variable 'Java_Home'.

I have installed oracle java JDK 8 to my new OS (Ubuntu)
but I couldnt find where should I add environment variable like in windows so that I can use java from any where of the system.
Can anyone help ?
Add these lines at the end of the user profiles in the ~/.profile file or, as a superuser, at the end of the global profiles in the /etc/profile file.
export JAVA_HOME=<jre installation home directory like /usr/lib/jvm/jrel.8.0>
export PATH=$JAVA_HOME/bin:$PATH
Logout and login again.
