방법1

intelliJ에서 잘 돌아가는데, 백준에서 틀림.

아시는 분은 댓글 달아주세요.

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.*;

public class Main {
    public static void main(String[] args) throws IOException {

        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

        List<Integer> newList = new ArrayList<>();
        for(int i=0; i<9;i++){
            newList.add(Integer.parseInt(br.readLine()));
        }
        int max = Collections.max(newList);
        int idx = newList.indexOf(max);

        System.out.println(max);
        System.out.println(idx);
    }
}
