What are the comments all are talking about in the programs? someone give me an example and write such a comment?

Program - 10 Marks, VD - 3 Marks, Comments - 2 Marks.
Also, In Comp Exam, Instruction is Given on the Question Paper: 

Each program should be written
using Variable descriptions/Mnemonic Codes such that the logic of the program is
clearly depicted.

So Please Write VD and Comments, or Lose 5 Marks.

Is it necessary to write comments? 'Cause I've never done it in school, nor have I been told to do so.

Question in comments

guys can someone give me notes for functions like math.ceil , floor etc

difference between protected n private access specifiers

Strings are immutable right ( mentioned in the text ) apart from theory i want to know the practical  application of that.......Like we often change the data of the string many times by using library functions like .toUpperCase or etc.....we use s=s.toLowerCase(); and we get the right output but why not it happens if we write directly s.toLowerCase instead of creating a seperate String object ?? i mean can anyone explain the diff and say how Strings are immutable...practical application is equally important right..so plz
