Do you guys know what the problem is. Please let me know what it is

Question

import java.util.Scanner;

class AddNumbers
{
public static void main(String args[])
{
int a,b,c,d,e;
int a=2;
int b=4;
int c=6;
int d=8;
System.out.print("Enter four even integers to calculate their sum :");
Scanner in = new Scanner(System.in);
a=in.nextInt();
b=in.nextInt();
c=in.next.Int();
d=in.next.Int();
e= a+b+c+d;
System.out.println("Sum of entered even integers = " + e);
}
}

Answer 1

Jayakrishna🇮🇳

I was not talking about missing dot (.) 😀😀

nextInt() is a method in scanner class so there should not be dot (.)

Answer 2

A͢J - S͟o͟l͟o͟H͟e͟l͟p͟e͟r͟ Ya, that was what I was talking about👍

Answer 3

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😅

Answer 4

//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);
}
}

Answer 5

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

Answer 6

A͢J - S͟o͟l͟o͟H͟e͟l͟p͟e͟r͟ And thanks for clarifying 😊

Answer 7

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.

Answer 8

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

Answer 9

A͢J - S͟o͟l͟o͟H͟e͟l͟p͟e͟r͟ Oh. Silly mistake..😔 How I write in reverse, I don't know..? May be confused.. 🤔.
Thanks. Corrected all now.
I will check once in playground..

Answer 10

Jayakrishna🇮🇳

You missed 2 more lines where correction should be done.

Answer 11

Learner_Pratham

Yes value will be override but he declared same variable two times.

Answer 12

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

Answer 13

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.

Answer 14

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