Question

static int findPerson(String n, int NP, Friend[] giftGivers){

    int index = 0;

    for (int i = 0; i < NP; i++){
    if (giftGivers[i].name == n){
            index = i;
    }
    }

    return index;
}

I have this code in Java for a method to search through an array of Friends to find the index number of the person with the name input by String n. however i have found that the index number does not set to the index number it is should be. Is it because it is in the if statement?

Answer 1

if (giftGivers[i].name == n) is wrong, use if (giftGivers[i].name.equals(n))

BTW, there is no need to use NP. It’s C-style, not necessary (actually, pretty dangerous) in Java. Instead of

for (int i = 0; i < NP; i++),

just say for (int i = 0; i < giftGivers.length; i++)
