As KhAn SaAb has stated  you need to set your path   But in order for your JDK to take advantage of tools such as Maven in the future  I would assign a JAVA HOME path to point to your JDK folder and then just add the  JAVA HOME  bin directory to your PATH   JAVA HOME    C  Program Files Java jdk1 8 0  PATH    PATH   JAVA HOME  bin     In Windows    right-click  My Computer  and choose  properties  from the context menu  Choose  Advanced system settings  on the left  In the  System Properties  popup  in the  Advanced  tab  choose  Environment Variables  In the  Environment Variables  popup  under the  System variables  section  click  New  Type  JAVA HOME  in the  Variable name  field Paste the path to your JDK folder into the  Variable value  field  Click OK In the same section  choose  Path  and change the text where it says     nbsp  nbsp  nbsp  nbsp  nbsp  nbsp blah blah blah C  Program Files Java jdk1 8 0 bin blah blah blah   nbsp  nbsp  nbsp  nbsp  nbsp  nbsp to    nbsp  nbsp  nbsp  nbsp  nbsp  nbsp blah blah blah  JAVA HOME  bin blah blah blah

Seems like you have your path right  But what is your working directory  on command prompt run   javac -version   this should show your java version  if it doesnt  you have not set java in path correctly   navigate to C   cd     Then   javac -sourcepath users AccName Desktop -d users AccName Desktop first java   -sourcepath is the complete path to your  java file  -d is the path directory you want your  class files to be  then finally the file you want compiled  first java

For Windows  javac should be a command that you can run from anywhere   If it isn t  which is strange in and of itself   you need to run javac from where it s located  but navigate to the exact location of your Java class file in order to compile it successfully   By default  javac will compile a file name relative to the current path  and if it can t find the file  it won t compile it   Please note   You would only be able to use jdk1 8 0 to actually compile  since that would be the only library set that has javac contained in it   Remember   the Java Runtime Environment runs Java classes  the Java Development Kit compiles them

I had the same issue and it was to do with my file name  If you set the file location using CD in CMD  and then type DIR it will list the files in that directory  Check that the file name appears and check that the spelling and filename ending is correct   It should be  java but mine was  java txt  The instructions on the Java tutorials website state that you should select  Save as Type Text Documents  but for me that always adds  txt onto the end of the file name  If I change it to  Save as Type All Documents  it correctly saved the file name
