Thread: Searching for object variables inside a 1-D array?

Hey there!

I've been working on a program, and I've made 10 objects of the class "CampSite". Each object has 7 different variables in it (name, postal code,number of campers in party etc...). I added these 10 objects to a 1-D array. I want to be able to add up all the number of campers that've been added into this array. How would I go about doing this?

Thanks!

This is a great use for the enhanced for loop or some other iterator of your choice:

for ( CampSite campsite : campsiteArray )
{
    // enter the search criteria and any other logic here
    // using the object 'campsite'. for example, if you want
    // to find the objects with 5 campers, find those where
    // campsite.numberOfCampers == 5
}

Good luck!

Hello.
Take a variable say sum initialized to zero.
Iterate through every object in the array. In every iteration add the number of campers to the variable sum.
After iterating is complete, sum contains what you want.
