An Issue about the Answer

The question was solved but there is one issue I would like to ask. For public static List<Integer> getIntegerList() throws IOException {, I created an list with the name list. but then for public static int getMinimum(List<Integer> array) { I tried to write for (int i=0;i<list.size();i++) but end up this is error. Why instead (int i=0;i<array.size();i++) is the correct answer? Since when the list name changed from list to array? I guess there is sth I misunderstood...thanks.

/*
Minimum of N numbers

public class Solution {
    public static void main(String[] args) throws Exception {
        List<Integer> integerList = getIntegerList();
        System.out.println(getMinimum(integerList));
    }

    public static int getMinimum(List<Integer> array) {
        // Find the minimum here

        int minimum = Integer.MAX_VALUE;
        for (int i=0;i<array.size();i++) {
            if (array.get(i)<minimum)
                minimum = array.get(i);
        }

        return minimum;
    }

    public static List<Integer> getIntegerList() throws IOException {
        // Create and initialize a list here
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        List<Integer> list = new ArrayList<>();
        int n = Integer.parseInt(br.readLine());
        for (int i=0;i<n;i++) {
            int a = Integer.parseInt(br.readLine());
            list.add(a);
        }
        return list;
    }
