Answer 2

For your program

import static java.lang.Math.*;

public void MedianFinder() {
System.out.print("Consider the sequence: ");
insertionSort();
display();
System.out.println();

int totalElements =nElems; // a.length;
int mIdx = (int)Math.floor(totalElements/2); // ceil floor
double median;

if (totalElements % 2 == 0) {
System.out.println("Total number of elements: " + totalElements + " (even) \n");
median = (a[mIdx-1]+a[mIdx])/2;
} else {
System.out.println("Total number of elements: " + totalElements + " (odd) \n");
median = (a[mIdx]);
}
System.out.println("Median is : " + median);
}

arr.MedianFinder();

Answer 3

public class Program{
public static void main(String arg[]) {
int n=5;
double a[]=new double[n];
a[0]=10;
a[1]=20;
a[2]=30;
a[3]=40;
a[4]=50;
double m=0;
if(n%2==1){ m=a[(n+1)/2-1];}
else{m=(a[n/2-1]+a[n/2])/2;}
System.out.println("Median :"+m);

}}
