Answer to Question #8914 in C# for khuli

Question

Your lecture wishes to store the exam marks for java,and perform an analysis of the marks.The marks are expressed as a percentage.There are 15 students that wrote the exam. Write the java program that will enable her to:
-input the marks for each student and store in an array called Supp.The input must be validated befoe being stored
-Determine and display the highest and lowest mark.
-Determine and display the average mark for the supplementary exam.
-Determine and display the mean and median(mean is calculated as the average of the lowest and highest marks)
E.g input:15 27 38 2 98 42 87 92 99 13 5 72 67 2 1
Output:
highest:99
lowest:1
median:38
average:44
mean:50

i'd be grateful for your help.
NB: URGENT!

import java.util.Arrays;
import java.util.Scanner;

public class Main {

private static Scanner input =new Scanner(System.in);
private static int Supp[]=new int[15];
public static void main(String[] args) {
for(int i=0;i<15;i++){
System.out.print("Input the mark for student "+(i+1)+": ");
Supp[i]=input.nextInt();
}
System.out.println("Highest "+Max(Supp));
System.out.println("Lowest "+Min(Supp));
System.out.println("Median "+Median(Supp));
System.out.println("Average "+Average(Supp));
System.out.println("Mean "+Mean(Supp));
}
//Median
private static double Median(int arayofNumber[]){
double median=0;

median=arayofNumber[7];
return median;
}
//Mean
private static double Mean(int arayofNumber[]){
double mean=0;

return mean;
}
//Sum
private static double Sum(int arayofNumber[]){
int sum=0;
for(int i=0;i<15;i++){

}
return sum;
}
//Function Min - smallest element in the array
public static double Min(int arayofNumber[]){

//Function Max - largest element in the array
public static double Max(int arayofNumber[]){
