Java basic projects

Question

The java basic projects slide #4 does not allow me to submit my answer and therefore I cannot progress through the class at all. Does anyone know how to solve this issue?

Answer 1

Where it is?
Can you link here...
The issue may be wrong answering..

Answer 2

Is it a page on Sololearn that you mean?

Answer 3

If it's from an external link, you may post the link but then it would not become a programming or Sololearn question.
