Java Exercises: Calculate the median of a given unsorted array of integers
Java Basic: Exercise-128 with Solution
Write a Java program to calculate the median of a given unsorted array of integers.
Example: {10,2,38,23,38,23,21}
Output: 23
Pictorial Presentation:
Sample Solution:
Java Code:
import java.util.*;
public class Main {
public static void main(String[] args)
{
int[] nums = {10,2,38,22,38,23};
System.out.println("Original array: "+Arrays.toString(nums));
System.out.println("Median of the said array of integers: "+getMedian(nums));
int[] nums1 = {10,2,38,23,38,23,21};
System.out.println("\nOriginal array: "+Arrays.toString(nums1));
System.out.println("Median of the said array of integers: "+getMedian(nums1));
}
public static int getMedian(int[] array) {
if(array.length % 2 == 0) {
int mid = array.length / 2;
return (array[mid] + array[mid - 1]) / 2;
}
return array[array.length / 2];
}
}
Sample Output:
Original array: [10, 2, 38, 22, 38, 23] Median of the said array of integers: 30 Original array: [10, 2, 38, 23, 38, 23, 21] Median of the said array of integers: 23
