Step 3) 

Click "Environment Variables"

Step 4) 

Click PATH and then "Edit" button, insert your Java Path to the end variable value, and then click "OK". for my case value i added is "C:\Program Files\Java\jdk1.8.0_65\bin;".

Remark: at usual your java would installed in "C:\Program Files\Java\" directory by default and there is a folder , some folders identified by your installed version number. Add path of bin folder where placed within the folder : for example: C:\Program Files\Java\jdk1.8.0_65\bin

Step5
Then go to the directory where your java files to be complied and run a command:

set path=your_java_bin_path;

In my case :

set path=C:\Program Files\Java\jdk1.8.0_65\bin;

And then you can compile your java by javac command:
