I think this is all you need to study for an introduction to Java.

I created a lecture by selecting the Java parts that are absolutely necessary for Android app development. The total lecture time is 13 hours and 30 minutes.

It will be very helpful if you organize it once before developing Android.

There are more lectures on the YouTube Soft Campus channel.

I hope it was helpful.
