Chapter: Math Class Last Updated: 05-05-2016 18:56:05 UTC

Program:

            /* ............... START ............... */
                
import java.util.*;

public class JavaMedianExample {

	public static void main(String[] args) {

		int scores[] = new int[] { 50,40,34,56,84,23,45,50,30,40 };

		Arrays.sort(scores);
		System.out.print("Sorted Scores: ");
		for (int x : scores) {
			System.out.print(x + " ");
		}
		System.out.println("");

		// Calculate median (middle number)
		double median = 0;
		double pos1 = Math.floor((scores.length - 1.0) / 2.0);
		double pos2 = Math.ceil((scores.length - 1.0) / 2.0);
		if (pos1 == pos2) {
			median = scores[(int) pos1];
		} else {
			median = (scores[(int) pos1] + scores[(int) pos2]) / 2.0;
		}

		System.out.println("Median: " + median);

	}
}

                /* ............... END ............... */
        

Output

Sorted Scores: 23 30 34 40 40 45 50 50 56 84 
Median: 42.5
