Java: a. The mean of a list of numbers is its arithmetic average. The median of a list is its middle value when the values are placed in order. For example, if a list contains 1, 4, 7, 8, and 10, then the mean is 6 and the median is 7. Write an application that allows you to enter five integers and displays the values, their mean, and their median. Save the file as MeanMedian.java. b. Revise the MeanMedian class so that the user can enter any number of values up to 20. If the list has an even number of values, the median is the numeric average of the values in the two middle positions.

1. Java:
a. The mean of a list of numbers is its arithmetic average. The median of a list is its middle value
when the values are placed in order. For example, if a list contains 1, 4, 7, 8, and 10, then the
mean is 6 and the median is 7. Write an application that allows you to enter five integers and
displays the values, their mean, and their median.
Save the file as MeanMedian.java.
b. Revise the MeanMedian class so that the user can enter any number of values up to 20. If the
list has an even number of values, the median is the numeric average of the values in the two
middle positions. Save the file as
MeanMedian2.java
Solution
Ans a):
import java.util.*;
import java.lang.*;
import java.io.*;
class MeanMedian
{
public static void main (String[] args) throws java.lang.Exception
{
Scanner scan=new Scanner(System.in);
int arr[]=new int[5];
System.out.println("Enter the integers :"); //asking the user to enter 5 integers
for(int i=0;i<5;i++)
arr[i]=scan.nextInt();
int sum=0;
for(int i=0;i<5;i++)
sum=sum+arr[i];
int mean=sum/5; //calculating mean
int median=arr[2]; //calculating median
System.out.println("Integers entered by the user ");
for(int i=0;i<5;i++)

2. System.out.print(arr[i]+" "); //printing values entered by user
System.out.println();
System.out.println("Mean = "+mean); //printing mean
System.out.println("Median = "+median); //printing median
}
}
******OUTPUT******
Enter the integers :
1 4 7 8 10
Integers entered by the user
1 4 7 8 10
Mean = 6
Median = 7
******OUTPUT******
