java程序 - 輸出不是預期的

Question

我遇到了我的程序輸出問題。它應該找到總降雨量，平均降雨量和雨量最少/最高的月份。該程序運行良好，但是當我運行它時，它總是將1月顯示爲最低（不顯示），而12月顯示最高（不顯示）。我希望找出我做錯了什麼。

public class RainFall { 
double[] rainArray = new double [SIZE]; 
public static final int SIZE = 12; 



RainFall() {  
} 
public RainFall(double[] r){ 
    rainArray = new double[SIZE]; 

} 

public void setArrayValueAtIndex(double Val, int Index) { 
    if (Index < SIZE - 1) 
     return; 

    rainArray[Index] = Val; 
} 

public double getTotal() { 
    double total = 0; 
    for (int i = 0; i < SIZE; i++){ 
     total += rainArray[i]; 
    } 

    return total; 
} 

public String getMonth (int monthIndex) { 
    switch(monthIndex) 
    { 
     case 0 : return "January"; 
     case 1 : return "February"; 
     case 2 : return "March"; 
     case 3 : return "April"; 
     case 4 : return "May"; 
     case 5 : return "June"; 
     case 6 : return "July"; 
     case 7 : return "August"; 
     case 8 : return "Septemeber"; 
     case 9 : return "October"; 
     case 10 : return "November"; 
     case 11 : return "December"; 
     default : return "Error"; 
    } 

} 


public double getAverage(){ 
    return (getTotal()/SIZE); 
} 

public String getMost(){ 
    int mostRain = 0; 
    for (int i = 1; i < SIZE; i++) 
    { 
     if (rainArray[i] > rainArray[mostRain]) 
      mostRain = i; 
    } 
    return getMonth(mostRain); 

} 

public double getMostValue(){ 
    int mostRain = 0; 
    for (int i = 1; i < SIZE; i++) { 
     if (rainArray[i] < rainArray[mostRain]) 
     mostRain = i; 
    } 
    return rainArray[mostRain]; 

} 

public String getLeast(){ 
    int leastRain = 0; 
    for (int i = 1; i < SIZE; i++) { 
     if (rainArray[i] < rainArray[leastRain]) 
      leastRain = i; 
    } 

    return getMonth(leastRain); 

} 

public double getLeastValue(){ 
    int leastRain = 0; 
    for (int i = 1; i < SIZE; i++) { 
     if (rainArray[i] < rainArray[leastRain]) 
     leastRain = i; 
    } 

    return rainArray[leastRain]; 
} 
     } 

有此計劃的兩個部分，但我相信它是這部分的問題是。

Answer 1

public double getMostValue(){ 
    int mostRain = 0; 
    for (int i = 1; i < SIZE; i++) { 
     if (rainArray[i] < rainArray[mostRain]) 
     mostRain = i; 
    } 
    return rainArray[mostRain]; 
} 

這將找到的最低值。您需要將<換成>。

Answer 2

我不明白，該方法是找到最小但最命名..

public double getMostValue(){ 
    int mostRain = 0; 
    for (int i = 1; i < SIZE; i++) { 
     if (rainArray[i] < rainArray[mostRain]) 
     mostRain = i; 
    } 
    return rainArray[mostRain]; 

}
