In Java Programming 8th edition chapter 9 #2-part b(MeanMedian2). How do I fix the following?

There is no type conversion for median in the second program.

You can use (double) casting operator at the beginning of the right hand side formula.

This is the program I used, it seems to work but I dont understand where exactly I am supposed to put the double.

import java.util.Arrays;

import java.util.Scanner;

public class MeanMedian2

{

public static void main(String[] args)

{

int list[] = new int[20];

int t,x,n=0;

double mean=0, median=0;

Scanner sc=new Scanner(System.in);

System.out.println("Please enter max of 20 numbers or NAN to exit");

try

{

for(int i=0;i<20;i++)

{

x=sc.nextInt();

list[i]=x;

n++;

}

}

catch(Exception e)

{

System.out.println("Thanks for the input");

}

for(int i=0;i

{

mean = mean+list[i];

}

mean = mean/n;

{

for(int i=0;i

{

for(int j=i+1;j

{

if(list[i]>list[j])

{

t=list[i];

list[i]=list[j];

list[j]=t;

}

}

}

int m=n/2;

if(n%2==0)

{

median=(list[m]+list[m-1])/2;

}

else median=list[m];

System.out.println("Mean is "+mean +" Median is "+median);

for(int i=0;i

{

System.out.println(list[i]);

}

}

}

}
