Answer 1

Yes, code is okay.

You read the number n in main, give that to the sum function and print the value returned:

// in main after scanner close
System.out.print(sum(n));

Answer 2

Just print sum after taking input

System.out.print(sum(n));

Method is used to perform a particular task so here sum method is performing a task to get total of all numbers from 1 to n

So here sum is a method which is accepting one parameter which is your input.

As sum method is returning total of 1 to n so we have to print that returned value.

You can either print by just calling method or you can store returned value to a new variable and then you can print that variable like this:

int sum = sum(n);

System.out.print(sum);

Answer 5

Answer 6

you didn't use sum method to get the result to print it

Answer 7

M O H A M E D im sorry how exactly?

System.out.print(sum); like how

Answer 8

you need tp pass the variable to sum method

Answer 9

sum take one int parameter

Answer 10

should i print the result in main method?

Answer 11

so (sum(n)) is basically giving the n(which is the input) to the sum method? like distributing the n to the sum method?

Answer 12

You have just to write System.out.println(sum(n));

Answer 13

You haven't called the sum function with the input as a parameter.
A great example as already mentioned quite a few times is:
System.out.print(sum(n)).

That way you're calling the sum function with your input as a parameter (in this case n). It does the calculations inside the sum function and prints the result.

Hope that helped!

Answer 14

Manav Roy the close function is to close the Scanner. If you don't close the Scanner then java won't garbage collect the Scanner and it might lead to memory leaks.
