Answer 1

try this:

public int getIndexOfMin(List data) {
    float min = Float.MAX_VALUE;
    int index = -1;
    for (int i = 0; i < data.size(); i++) {
        Float f = data.get(i);
        if (Float.compare(f.floatValue(), min) < 0) {
            min = f.floatValue();
            index = i;
        }
    }
    return index;
