Question

I need to find smallest and second smallest number in a list.

Can I do this using single loop?
Also, we need to consider the case of two multiple occurences of a number.

Ex: 1. from list [20,30,90,50] output 20 ,30
2. from list [30,30,90,50] output 30 ,30

plz help

I am sorry, Actually I dont have list of Integers. But I ahve list of objects.

Anyways, thanks for the help. I hope the following code works

if (minimum==0 || obj.getValue() < minimum) {
    second = minimum;
    minimum= obj.getValue();
} else if (obj.getValue() < second || second==0) {
    second = obj.getValue();
}
