Java Array Exercises: Compute the average value of an array of integers except the largest and smallest values
Java Array: Exercise-29 with Solution
Write a Java program to compute the average value of an array of integers except the largest and smallest values.
Pictorial Presentation:
Sample Solution:
Java Code:
import java.util.*;
import java.io.*;
public class Exercise29 {
public static void main(String[] args)
{
int[] array_nums = {5, 7, 2, 4, 9};
System.out.println("Original Array: "+Arrays.toString(array_nums));
int max = array_nums[0];
int min = array_nums[0];
float sum = array_nums[0];
for(int i = 1; i < array_nums.length; i++)
{
sum += array_nums[i];
if(array_nums[i] > max)
max = array_nums[i];
else if(array_nums[i] < min)
min = array_nums[i];
}
float x = ((sum-max-min) / (array_nums.length - 2));
System.out.printf("Compute the average value of an array of integers except the largest and smallest values: %.2f",x);
System.out.print("\n");
}
}
Sample Output:
Original Array: [5, 7, 2, 4, 9] Compute the average value of an array of integers except the largest an d smallest values: 5.33

How to sort an ArrayList?
Collections.sort(testList); Collections.reverse(testList);
That will do what you want. Remember to import Collections though!
