can somone explain that "comments" lesson from java language?

Question

im a beginner, need some help please? ;)

Answer 1

Whatever you write in a comment doesn't affect your code, that comment being just a simple comment(in the real meaning of the word), that explains the others what you did and maybe sends a message or explains to you what you did, after a long time.

Answer 2

what doubt U got in that lesson ?
//there are examples available too ,
comments are ignored by the compiler , its the text which might be needed to understand the code better & to provide some information
//probably U got doubt in "documentation comments" ... right ?
for that U must follow comment section of documentation comment lesson , wait I will be posting some links also

/*is
