[英]I want to find the average in a given array, and find the closest number to that average in java
I want to calculate the number closest to the average of the array, I have finished calculating the average but I have no idea how to find the closest number to that average.我想计算最接近数组平均值的数字,我已经完成了平均值的计算,但我不知道如何找到最接近该平均值的数字。
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();
}
} }
To find the average in the given array and find the number which is closest to the average,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);
}
