I am also new to java and extension development.
Some steps which I followed.
- Daily watch tutorials and guides on youtube, approx 1 hour.
- Trying to build extension!
- Results - If fail
- Do some research in google/stackoverflow
- If it doesn't help me
- Get help from others (not to ask full)
- Else - Next code
You know today I took more than 2 hours solving problems in my BinaryTools extension, finally passed!
