Question

我有这个问题，我应该编写代码并检查数组中数字的可分性，数字（goodValue和badValue）..如果好的和坏的值可以被数组中的数字整除，我们添加+2，如果数字可以被良好的值整除，我们加+1，如果该值只能被badValue整除，我们减1。

public class Array {
    static int[] ArrayA ={8, 4, 3, 12, 7, 9};
    static int[] ArrayB ={3, 8, 14, 12, 10, 16, 6};
    static int score;

public static void main(String [] args){

    score = scoreArray(ArrayA, 2, 3);
    System.out.println("First score for arrayA: " + score);
    score = scoreArray(ArrayA, 3, 4);
    System.out.println("Second score for ArrayA: " +score);
    score = scoreArray(ArrayB, 5, 2);
    System.out.println("First score for ArrayB: " +score);
    score = scoreArray(ArrayB, 3, 7);
    System.out.println("Second score for ArrayB: " +score);


}

private static int scoreArray( int [] theArray, int goodValue, int badValue){
    for (int i=0; i<=theArray.length; i++){
        if((i%goodValue & i%badValue)==0){
            score=+2;               
        }
        else if (i%goodValue==0){
            score=+1;
        }
        else if((i%badValue==0)){
            score= -1;
        }
        score+=score;
    }

    return score;

    }
}

我应该得到这个

Firts score for arrayA: 1
Second score for arrayA: 3
First sccore for arrayB: -3
Second score for ArrayB: 2

我正在接受这个

First score for arrayA: 2
Second score for ArrayA: 2
First score for ArrayB: 2
Second score for ArrayB: 2

Answer 1

是你输错了......

score=+2;

应该是

score += 2;

与其他语句类似，它应该是

score += 1;

和

score -=1;

我想我并不完全理解你在问题中提到的措辞。你在一个地方使用数字而在另一个地方使用数值，这让我感到困惑。

我改进了分数计算逻辑，但没有给出你期望的确切答案

private static int scoreArray( int [] theArray, int goodValue, int badValue){
            score = 0;
    for (int i=0; i<theArray.length; i++){
        if(((theArray[i]%goodValue)==0) && ((theArray[i]%badValue)==0)){
            score += 2;             
        }
        else if (theArray[i]%goodValue==0){
            score+=1;
        }
        else if((theArray[i]%badValue==0)){
            score -= 1;
        }
    }
    return score;
    }
}

Answer 2

 public class Array 
{
static int[] ArrayA ={8, 4, 3, 12, 7, 9};
static int[] ArrayB ={3, 8, 14, 12, 10, 16, 6};
static int score=0;

public static void main(String [] args)
{

score = scoreArray(ArrayA, 2, 3);
System.out.println("First score for arrayA: " + score);
score = scoreArray(ArrayA, 3, 4);
System.out.println("Second score for ArrayA: " +score);
score = scoreArray(ArrayB, 5, 2);
System.out.println("First score for ArrayB: " +score);
score = scoreArray(ArrayB, 3, 7);
System.out.println("Second score for ArrayB: " +score);


}

public static int scoreArray( int [] theArray, int goodValue, int badValue)
{    score =0;
for (int i=0; i<theArray.length; i++)
{

 if(((theArray[i]%goodValue)==0) && ((theArray[i]%badValue)==0))
  {

      score = score+2;           

  }
   else if (theArray[i]%goodValue==0)
    {
       score = score+1;   
    }
    else if((theArray[i]%badValue==0))
    {
       score = score+(-1);  
    }



}
return score;
 }
  }

根据您的要求，它可以正常工作......如果您的评论发布任何问题。

  output
  First score for arrayA: 2   
  Second score for ArrayA: 2
  First score for ArrayB: -3
  Second score for ArrayB: 2

添加计数值（for循环）
