Java Program to calculate sum of N given numbers

Get input n and n inputs and calculate the sum of n inputs.

Sample Input 1:

4 6 5 3 2

Sample Output 1:

The sum is: 16

1. Get input n (How many values to be added)

2. Instruction(s) inside the for block{} are executed repeatedly till the second expression (j<=n) is true.

for(i=1;i<=n;i++)

3. Here i is initialized to 1 and incremented by 1 for each iteration, instructions inside the for block are

executed in every iteration. iteration stops when i becomes greater than n.

num=sc.nextInt();

sum=sum+num;

so value of num given by user will be added to sum at each iteration.

sum = sum + num

sum = 0 + 5 (if 5 given)

sum = 5 + 2 (if 2 given)

sum = 7 + 9 (if 9 given)

...........

after adding all n numbers given by user to sum, sum will be printed using system.out.println.
