Java评分方法

Question

目前正在执行一个程序来确定某个国家/地区的最高分。我遇到的问题是确定如何通过用户的输入获得得分最高的国家/地区。主要关心的是输出得分最高的国家及其赢得的奖牌(除美国外赢得 2 金 1 银 1 铜)。我只关心美国方法的自动取款机。我对我关心的领域发表了一些评论。

import java.util.Scanner;
class OlympicMedalsEM
{
public static void main (String[] args)
{
    Scanner kb = new Scanner(System.in);
    int winner=0;
    String countrywin;
    int gold=0, silver=0, bronze=0, count=0, num=0, sum=0;      //num as in the number of countries
    int goldscore=0, silverscore=0, bronzescore=0;
    String country;
    {
    System.out.println("Please choose a scoring method. a for American or c for Canadian. ");
    char again = kb.next().charAt(0);
        if(again == 'a')//american method
        {
            // American method counts the medals with the most score. ex: gold is worth 3, silver 2, and bronze 1.
            // USA win 3 gold 1 silver 0 bronze = 11 points so to speak.
            {
            System.out.println("Enter the number of countries competing: ");
            num = kb.nextInt();
            {
            for (int x=0; x < num; x++)

                // need it to also figure out how to pick the country with the high quality of medals

这样想吧。如果一个国家的奖牌数输入比之前少，为什么还要继续存储呢。为当前最高值设置一个变量，仅在需要时覆盖它们。

int currentHigh = 0;
int noOfCountries = 10;
int input;

for(int i=0; i<noOfCountries; i++) {
    input = in.nextInt();
    if(input>currentHigh) {
        currentHigh=input;
    }
}
