Question

I'm getting an error whenever running this program??? I don't see why. Can anyone help?

public class evenPercent{

   public static void main(String[] args) {

       double [ ] a = {3, 4, 5, 7, 8};

       arraySum(a);

   }

   public static void arraySum(double[ ] a){

       int sum = 0;

       for(int i = 0; i <= a.length; i++){

           double BusyP = a[i];

               if(BusyP % 2 == 0){

               sum++;

               }

       }

       double percent = (sum)/(a.length);

       System.out.println(percent + "% of your values are even");

   }

}

Explanation / Answer

The for loop is executed for 6 times where as you array has 5 elements only.

Please change the for loop as below.

for(int i = 0; i < a.length; i++)

*************Modified code ***************************

public class evenPercent{
     
public static void main(String[] args) {
  
double [ ] a = {3, 4, 5, 7, 8};
  
arraySum(a);
  
}

public static void arraySum(double[ ] a){

int sum = 0;
  
for(int i = 0; i < a.length; i++){
  
double BusyP = a[i];
  
if(BusyP % 2 == 0){
  
sum++;
  
}
  
}
  
double percent = (sum)/(a.length);
  
System.out.println(percent + "% of your values are even");
  
}
  
}
