Question

Using java prompt the user to enter an integer called n. Then scan in n values of type double.Find the middle value of the n numbers using a for loop. Assume the middle value is the ((n+1)/2) th number entered.

Answer 1

//MiddleNumber.java
import java.util.Scanner;
public class MiddleNumber {
    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        System.out.print("Enter number: ");
        int n = scan.nextInt();
        double result = -1, k;

        System.out.println("Enter "+n+" double values");
        for(int i = 0;i<n;i++){
            k = scan.nextDouble();
            if((i+1)==((n+1)/2)){
                result = k;
            }
        }

        System.out.println("Middle value: "+result);
    }
}
