System.out.println(ABcd.substring(2))

Answer 1

If you put ABcd in quotation marks, then it makes sense.
You can search the JDK documentation to understand how the standard library works.
https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/lang/String.html
The number argument, is the begin index.

I don't know. ABcd is thus far not defined...

In Challenge question doesn't make sense of copy paste instead there should be explanation but as challenge questions were posted by community member so I think that is why not available.
For the image in QA you can do one thing take screenshot, upload image in post and then share the post link with question.
