Java is not recognized as an internal or external command

Question

When trying to check the current version of Java in which I am running  I received the error  quot java is not recognized as an internal or external command  operable program or batch file  quot   I am running Windows 7 OS and have downloaded the latest JDK and felt I may have accidentally deleted the java from machine as before I was able to check the Java version using the command  quot java -version quot   What software must I download to get Java working on my machine again  EDIT  I have managed to get Java running from my cmd again after ensuring all environment variables pointed to the current Java SDK

For Windows 7    Right click on My Computer Select Properties Select Advanced System Settings Select Advanced tab Select Environment Variables Select Path under System Variables Click on Edit button In Variable value editor paste this at the start of the line  C  Program Files Java jdk1 7 0 72 bin   Click Ok then Ok again Restart command prompt otherwise it won t see the change to the path variable Type java -version in command prompt     Notes on Step 8  1  The version of java in this may be different from the one used here -- this is only an example  2  There will probably be other values in the path variable  It is really important that you don t delete what s already there  That s why the instructions say to paste the given value at the start of the line -- this means that you don t remove the existing value  you just put java before it  This also fixes any problems you d be getting if an other version of java is also on the path     Notes on Step 6  1  This sets the path for the computer  not for the individual user  It may be that you re working on a computer which other developers also use  in which case you d rather set the user variables  rather than the system variables

It sounds like you haven t added the right directory to your path   First find out which directory you ve installed Java in  For example  on my box it s in C  Program Files java jdk1 7 0 111  Once you ve found it  try running it directly  For example   c   gt   c  Program Files java jdk1 7 0 11 bin java  -version   Once you ve definitely got the right version  add the bin directory to your PATH environment variable   Note that you don t need a JAVA HOME environment variable  and haven t for some time  Some tools may use it - and if you re using one of those  then sure  set it - but if you re just using  say  Eclipse and the command-line java javac tools  you re fine without it     1 Yes  this has reminded me that I need to update

My solution was to put same value  path to JDK bin folder  in JAVA HOME and Path

User · Answer

You need to configure your environment variables  JAVA HOME and PATH   JAVA HOME must contain the path to java  and you should add  JAVA HOME  bin to PATH  Alternatively  you can simply add to your PATH the whole path to the bin folder  without the JAVA HOME variable  however  this makes a little more annoying when you need to have more than one java version on your machine  that way you only need to change JAVA HOME and don t even bother with PATH
