=====================================================

Explanation:

⇒ Scanner class is created by the key word " new "

⇒ System.out.println is used for printing the very next line !

⇒ The Blue J version which is more than 3.0 may not give static keyword.      

⇒ They can write public void main()

⇒ First we take all inputs , then we add the marks in variable total

⇒ Ultimately average = sum of all marks { total } / number of subjects

⇒ I have taken the average in double for accuracy in calculation !

⇒ I used BlueJ to compile

⇒ The output screen in the attachment.

==============================================================

OUTPUT :

I_hate_studies.main({ });

Enter the name of your dear student

Jishnu

Dear enter the register number please

000000001

Last one sorry for troubling..... enter marks of 5 subjects

Average marks = 34.8
