我想在给定的数组中找到平均值，并在java中找到最接近该平均值的数字

Question

我想计算最接近数组平均值的数字，我已经计算完平均值，但我不知道如何找到最接近该平均值的数值。

public class ClosestToTheArray {
int array [] = new int[]{1, 2, 3 ,4 ,5, 6 ,7 ,8};
int sum;
int sum2;
public void findAverage(){
double avg;
double lol = 0;
double smthelse;
for(int i =0; i < array.length; i++){
sum += array[i];
}
avg = sum/array.length;
}
public static void main(String [] args){
ClosestToTheArray test = new ClosestToTheArray();
test.findAverage();
}

}

Answer 1

要在给定数组中找到平均值并找到最接近平均值的数字，

public static void main(String[] args)
{
int array[] = new int[]
{ 1, 2, 3, 4, 5, 6, 7, 8 };
int sum=0;
double avg;
for (int i = 0; i < array.length; i++)
{
sum += array[i];
}
avg = sum / array.length;
System.out.println(avg);

double difference = Math.abs(array[1] - avg);
Integer closest = array[1];
for (int i = 0; i < array.length; i++)
{
double diff = Math.abs(array[i] - avg);
if(difference > diff)
{
difference = diff;
closest = array[i];
}
}
System.out.println(closest);
}
