Question

Design and implement an application called Mean.java that computes and prints the mean of two lists of integers coming from the same list that has n numbers: x0, x1, …, xn-1. The first list L1 contains x0, x2, …, through xn-1 if n is odd or through xn-2 if n is even. The second list L2 contains x1, x3, …, through xn-1 if n is even or through xn-2 if n is odd. Ask the user to input n and read the value of n. Then ask the user to input n integers and save them in an array. Print out L1 and compute the mean as a floating point value for L1. Then print out L2 and compute the mean as a floating point value for L2, using the following formula:

           public void computemean()

{
        Scanner input = new Scanner(System.in);
        System.out.println("number of even number array 1 : ");
        //get number
        int n = input.nextInt();
        //create array with size n
        int[] array = new int[n];
        //initialize the initial value of sum
        int sum = 0;
        //get the input numbers using for loop
        for (int m = 0; m < n; m++) {
            System.out.print("Array element " + m + " : ");
            array[m] = input.nextInt();
        }


Scanner input1 = new Scanner(System.in);
        System.out.println("number of odd numbers in array 2 : ");
        //get number
        int n1 = input.nextInt();
        //create array with size n
        int[] array1 = new int[n];
        //initialize the initial value of sum
        int sum1 = 0;
        //get the input numbers using for loop
        for (int m1 = 0; m1 < n1; m1++) {
            System.out.print("Array element " + m1 + " : ");
            array1[m1] = input.nextInt();
        }



        //calculate sum of all array elements
        for (int m = 0; m < n; m++) {
            sum = array[m] + sum;
        }

        
            System.out.println("Total value of array element1 = " + sum);
      
        
            double meanreq;
            //calculate average value
            meanreq = sum / array.length;
            System.out.println("Average of Array 1 = " + meanreq);



//calculate sum of all array elements
        for (int m1 = 0; m1 < n1; m1++) {
            sum1 = array[m1] + sum1;
        }

        
            System.out.println("Total value of array element 2 = " + sum1);
      
        
            double meanreq1;
            //calculate average value
            meanreq1 = sum1 / array1.length;
            System.out.println("Average of Array 2 = " + meanreq1);
        
    }
}
}
