從第二個陣列返回值

Question

當前我的代碼返回用戶輸入每個月的溫度值時提交的最高溫度值。我怎樣才能讓程序以最高的條目返回月份，而不是最高的條目本身？

import java.util.Scanner; 

public class Reader { 

static String months[] = 
    { 
      "January" , "February" , "March" , "April" , "May" , 
      "June", "July", "August", "September", "October", "November", 
      "December" 
    }; 

public static void main(String[] args){ 

    int[] avgMonth; 
    int tempRecords = 0; 
    double tempSum = 0; 
    double avgTemp; 
    double getHotMonth; 

    //collect user input for avg temp and put into an array with the month 
    Scanner input = new Scanner(System.in); 
    avgMonth = new int[months.length]; 
    for(int i=0; i < months.length; i++){ 
     System.out.println("Enter the average temperature for the month of "+months[i]); 
     avgMonth[i] = input.nextInt(); 
    } 


    //call avgTemp, takes array of temps as argument, return total avg for year 
    for(int i=0;i<months.length; i++) 
     tempSum += avgMonth[i]; 

    avgTemp = tempSum/months.length; 

    //call getHotMonth, takes entire array as argument, find index of hottest month 
    getHotMonth = avgMonth[0]; 
    for (int i=0;i<months.length;i++){ 
     if (avgMonth[i] > getHotMonth) 
      getHotMonth = avgMonth[i]; 
    }  

    //displayResults, display average and hottest month 
    //args are average and the index array number of hottest month 
    //final output 

    displayResults(avgTemp,getHotMonth); 

    input.close(); 

}//close main 

public static void displayResults(double average, double getHotMonth){ 
    System.out.println("The average temperature for the year was "+average+" degrees F with "+getHotMonth+" being the hottest month."); 

} 
}

您需要的迭代過程中捕獲hotMonth以及並把它作爲參數傳遞給displayResults方法如下所示：

public static void main(String[] args){ 

    //add your existing code 

    String hotMonth=""; 
    for (int i=0;i<months.length;i++){ 
     if (avgMonth[i] > getHotMonth) { 
      getHotMonth = avgMonth[i]; 
      hotMonth = months[i];//capture hotMonth 
     } 
    }  
    displayResults(avgTemp,hotMonth); 
    } 

    public static void displayResults(double average, String hotMonth){ 
    System.out.println("The average temperature for the year 
     was "+average+" degrees F with "+ 
     hotMonth+" being the hottest month."); 
    }
