Jayakrishna🇮🇳 I was not talking about missing dot (.) 😀😀 nextInt() is a method in scanner class so there should not be dot (.)

Marianne I guess😮, the problem is in the declaration of variables. You have declared it already during -> int a,b,c,d,e; and you declared it once more individually😐. It doesn't make sense😓. I think that should be the problem😅

//corrected code import java.util.Scanner; class AddNumbers { public static void main(String args[]) { int a,b,c,d,e; System.out.println("Enter four even integers to calculate their sum :"); Scanner in = new Scanner(System.in); a=in.nextInt(); b=in.nextInt(); c=in.nextInt(); //nextInt(); not next.Int() d=in.nextInt(); e= a+b+c+d; System.out.println("Sum of entered even integers = " + e); } }

Jayakrishna🇮🇳 I think, the initialisation of the variables done earlier would be overridden by the values entered, wouldn't it??

Learner_Pratham yes. you are right.. A͢J - S͟o͟l͟o͟H͟e͟l͟p͟e͟r͟ Are you taking about next.Int(); dot (.) ×missing?× √edit: extra dot? Yes. I did not check on playground. Edited now... Marianne last 2 lines having next.Int() ; extra a dot(.) a,b, c, d, e are already declared so I commented redefining... edit: not missing. in fact extra dot.

Marianne Jayakrishna🇮🇳 Yes, The dot operator shouldn't be there.

Jayakrishna🇮🇳 Yes, I didn't noticed that Marianne as well as you😄 used a dot operator between 'next' and 'Int()'

Pay attention to your basic algorithm. Here you apply this algorithm: start : variable: a: int write ("Enter a number") a = read entered number return 4 * a end You only wrote one number and read four times. This is equivalent to reading the only number entered four times. you can store your numbers in a number array using a loop that iterates through the array filling it. Finally you calculate the sum of the numbers stored in your table.

When you are taking input for c and d , it should be "in.nextInt()" ... and else it looks fine!
