How do I return the sum of an array, with this code to start it off?

Question

So this is what I have:

public static void Positive () {
    int limit = 50;
    for(int i=1; i <= limit; i++){
        System.out.print(i + ", ");
    }
}

That prints out all numbers 1-50 with a loop

How do I return the sum of this using a loop?

Here's a hint - Have a counter inside the loop, and add ```i``` to it each time. — Siddhartha, Oct 19 '15 at 22:56
No, don't do that. Have a counter *outside* the loop. If it was inside, it would be local to the loop and get destroyed after each iteration. — Luke Joshua Park, Oct 19 '15 at 22:58
Maybe something like [Returning a Value from a Method](https://docs.oracle.com/javase/tutorial/java/javaOO/returnvalue.html) — MadProgrammer, Oct 19 '15 at 23:00

I changed the return type to int.

public static int Positive () {
    int limit = 50;
    int sum = 0;
    for(int i=1; i <= limit; i++){
        System.out.print(i + ", ");
        sum += i;
    }
    return sum;
}

Another approach

int sum = 0; 

for (int i = 1; i <= 100; i++) {

sum += i; 

}

You havent cleared yet that you want to return the value or just print it from the function so you can use either of the approach in answers of your question. One with int type can return the value and print as well

Here is what you can do

public static void Positive () {
int limit = 50;
int total = 0;
for(int i=1; i <= limit; i++){
    total = total + i;
   }
System.out.print(total);
}
