Question

public class Elections1 {

    public static int visit(String[] likelihoods){
        double smallestPer=1.00;
        int smallestIndex=0;

        //Go through each element inside likelihoods
        for(int i=0;i<likelihoods.length;i++){
            String likelihood = likelihoods[i];

            // Calculate the percentage
            int countOfOne = 0;

            //What to include here???

            double percentage = (double)countOfOne/likelihood.length();

            //Store the smallest value by comparing the smallest percentage
            if(percentage < smallestPer){
                smallestPer = percentage;
                smallestIndex = i; 
            }
        }

        //Return the index number
        return smallestIndex;
    }

    public static void main(String[] args) {
        String[] likelihood={"1222","1122","1222"};

        System.out.println(visit(likelihood));
    }
}

我需要返回喜欢中最小百分比的索引号，我可以在＆＃34;计算百分比＆＃34;中包含哪些陈述。对于每个possibles.length？

如果你希望函数只是在数组中找到最小的百分比，并且数组由字符串形式的百分比组成，那么你可以将字符串解析为整数并进行比较。

假设您希望1222,1122和1222分别为12.22％，11.22％和12.22％，那么将字符串解析为整数并进行比较就足够了。

话虽如此，您不需要声明实际声明的许多变量。

public class Percentages {

  public static int visit(String[] likelihoods) {
    int smallestPer = Integer.MAX_VALUE;
    int smallestIndex = 0;

    //Go through each element inside likelihoods
    for (int i = 0; i < likelihoods.length; i++) {

      int likelihood = Integer.parseInt(likelihoods[i]);

      //Store the smallest value by comparing the smallest percentage
      if (likelihood < smallestPer) {
        smallestPer = likelihood;
        smallestIndex = i;
      }
      if (likelihood == 0) {
        return i;
      }
    }

    return smallestIndex;  
  }

    public static void main(String[] args) {
        String[] likelihood = {"1222","1122","1222"};

        System.out.println(visit(likelihood));
    }
}

这对我有用。这是你想要的吗？
