classes.dex file does't contain my java classes

enter image description here

I have developed an app in android studio and test it in my phone. I have formatted my computer and forgot to save my project to somewhere. Now i want to get my source codes back. I get the APK file from my phone (either by using adb and some other tools).

I am using dex2jar and decompile my classes.dex file but it does not show my own Java classes. Is it possible to get them back?
