Javac doesn t work correctly on Windows 10

Question

the problem is that I upgraded to Windows 10 and now I m installing my tools to programming and now that I installed the JDK 7 of Java  when I try to use in the cmd the command  -  quot javac quot  The result of this is   quot javac quot  is not recognized as an internal or external command    But I was edited the PATH with the correct link of jdk  because when I use  quot java quot   it is ok  Now  I tried in the console with this command  PATH  PATH   quot C  Program Files Java jdk1 7 0 79 bin quot  And when I executed the command  quot javac quot  it works  but now  when I open other console  it doesn t work  or when I restart the console  this command is not recognized  What could be the problem

just add C  Program Files Java jdk1 7 0 80 bin as the path in environmental variables  no need to add java exe and javac exe to that path  IT WORKS

I had the same issue on Windows 10 - the java -version command was working but javac -version was not  There are three things I did    1  I downloaded the latest jdk  not the jre  and installed it  Then  I added the jdk bin path tan o environment variable  In my case  it was C  Program Files Java jdk-10 bin  I did not need to add the   for Windows 10    2  Move this path to the top of all the other paths    3  Delete any other Java paths that might exist    Test the java -version and javac -version commands again  Voila

java is part of the JRE  not the JDK   You need to add the JDK bin to the system PATH  in    Control Panel    System   Advanced    Environment Variables

The PATH is for current user  instead you can add a CLASSPATH and below link would help you more PATH and CLASSPATH

in the search window type  environment variables  this should give you a link to editing the variables  On the variables editing page there is an upper section and a lower section in the lower section add NEW type path C  Program Files Java jdk-10 bin this worked great for me and it finds the compiler all the time

User · Answer

To be sure about your path  you can use double quotes   to locate the path or if you are in Windows  you can browse to path to select  C  Program Files Java jdk1 8 0 121 bin  folder

Kind of beating a dead horse now but  I want to clarify one thing that may not be quite so obvious  Yes indeed you need to edit the PATH environment variable as already stated many times  The key for me was to edit the PATH under SYSTEM variables  I had inadvertently edited the PATH under USER variables  Why did this matter  On my machine I have to log in as an Administrator to edit environment variables  So editing the User variables was not helping because I run the command prompt under my login  non-admin  account  Grrr   Also  I found that closing the command prompt window  and re-opening it after the PATH variable update was required  Changing the order of the values  adding semi-colons  etc  didn t make a difference for me   Cheers

If you have set all PATH variables correctly after installation  just restart it   I had the same problem  I had also installed new Windows7 OS then I upgraded it to Win 10  Then i started setup necessary tools like IntelliJ  Java jdk jre  eclipse so on  In cmd  java -version worked but javac compiler got unrecognized  I checked and all good  the files in the folders  path are  correct and so on    I restarted and checked it again in cmd  it worked

For some reason it worked for me to add quotation marks to the path folder on windows 10  not C  Program Files Java jdk 1 8 0 111 bin  but  C  Program Files Java jdk 1 8 0 111 bin

User · Answer

now i got it finally    make sure that there are no spaces before and after the path and put the semi-colon on both sides without spaces

I am totally new to java and spent hours trying to get the problems with PATH and CLASSPATH worked out  There was one person who said to restart the command prompt after you modify the environment variables  that was it for me  While you are testing different configurations  make sure to relaunch the command prompt before testing  It seems like there are at least 2 different ways of setting this up  I went with the following   1  In System Variables  add      JAVA HOME   c  program files  x86  java jdk1 8 0 121   2  In System Variables  add the following to existing Path          JAVA HOME  bin   That s it   No need for quotes around anything  No double forward slashes or anything else  I think it would also work if I removed the java home variable and just listed the explicit path to bin in the PATH variable  but I m not touching it again now that it finally works

Add java path to environment variables and move it to the top of all the paths available there  It worked for me

User · Answer

what I did is   I typed   accidentally in front in the path variable and then hit OK  after this if I again edit it was nowhere going to the same page as earlier  it opened a new page as defined for user variables and then I was able to remove double quotes in front of the PATH VARIABLE  Everything worked fine then      Did it just now
