    	// initialize and declaring the objects.
        int n, i, sum=0, mean;
        int arr[] = new int[50];
        Scanner scan = new Scanner(System.in);
        // enter number you have to enter.
        System.out.print("How many Number you want to Enter : ");
        n = scan.nextInt();
        // enter the numbers.
        System.out.println("Enter " +n+ " Numbers : ");
        // this will access all numbers and make sum of the numbers.
        for(i=0; i<n; i++)
            arr[i] = scan.nextInt();
            sum = sum + arr[i];
        // fomula to calculate mean.
        mean = sum/n;
