I am learning Java and I had unintall old version and install new
I can not open eclipse,
After I click on eclipse I see following error:
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:\Program Files \Java\jdk-15\bin/javaw.exe
Java version and eclipse error
The folder for usr/java/jdk1.8.0_241 and usr/lib/jvm/jdk1.8.0_241
Sadly the installation seems to have several problems
When I open Eclipse I get the following error :
A Java Runtime Environment (JRE) or Java Development Kit (JDK) must be available in order to un Eclipse. No java Virtual machine was found after searching the following locations :
usr/lib/jvm/jdk1.8.0_241/default.ee
usr/lib/jvm/jdk1.8.0_241/java
usr/lib/jvm/jdk1.8.0_241/libjvm.so
Further information :
~/bashrc wasn't changed
/etc/environment
eclipse.ini
I downloaded jdk-8u241-linux-x64
i am having difficults to repair my eclipse due this problem:
"A JRE or JDK must be available in order to run eclipse. No virtual machine
was found"
i looked the path that contains the \bin file to that is missing and realized that my jdk and jre has different versions (jdk 1.8.0_102 jre 1.8.0_112)
could be this the problem? if yes, how can i update them both?
i search in the oracle website but didn't found an older version of jre
how could be the better way to fiz this problem,
tks

I extracted ADT and when I'm trying to run eclipse get a error,
"A Java Runtime Environment (JRE) or Java Devolpment Kit (JDK)
must be available in order to run Eclipse. No Java virtual machine
was found after searching the following location:
C:\Development\adt-bundle-windows-x86_64-20140702\eclipse\jre\bin\javaw.exe
javaw.exe in your current PATH"
I've installed JDK 7, but still not working. how do I fix this?
When I open adt-bundle-windows-x86_64-20131030 and click on the Eclipse.exe application to install it I get the message; 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:\users\username\desktop\development\adt-bundle-windows-x86_64-20131030\eclipse\jre\bin\javaw.exe
javaw.exe is your current PATH.
I do have JDK, and JRE on this computer, I need them to view the emulator for my job. I have tried uninstalling and reinstalling Java with the same results. What can I do to fix this problem?
You will have to put Java in your classpath, so Eclipse knows where it can find Java. See here: http://docs.oracle.com/javase/tutorial/essential/environment/paths.html for info on how to do this.
install 32 bit version of jdk from oracle website
put the path of your java bin directory under Environment variables.
System->Advanced System Settings->Environment Variables->path
Open command prompt. use java and javac commands to know if you have successfully installed java and compiler.
if it doesn't help, this question has a lot of helpful answers
Eclipse - no Java (JRE) / (JDK) ... no virtual machine
From what you said:
"'java' is not recognized as an internal or external command, operable program or batch file"
Your java may not have been installed correctly, or, it was installed, but you did not set path to it correctly. It is not a problem with ADT, any of your programs that need Java will not be able to find it.
