Question

Create global variables Mean, Mode, Median, then create a method that takes an array of 10 double numbers and return three answers of the Mean, Median, Mode ( no need for implementation of the mean, median and mode, calculate them manually and return the answers), assign the answers to the global variables.

In java, please!!

Answer 1

The following is the code for above question. As it is stated in the question that there is no need to implement the logic for mean,median and mode, I just manually calculated for given array and assigned to global varibales. In java, inorder to declare a variable global, we have to declare it using static keyword at start of the code.

import java.util.*;
public class Main
{
    public static double Mean,Median,Mode;
        public static void main(String[] args) {
                double[] values = new double[]{2.5,4.42,5.2,2.1,6.2,3.4,5.9,6.1,9.3,2.5}; //double array of values
                calculate(values);
                System.out.println("Mean is "+Mean);
                System.out.println("Median is "+Median);
                System.out.println("Mode is "+Mode);
        }
        public static void calculate(double[] values)
        {
            Mean=4.084;
            Median=5.2;
            Mode=2.5;
        }
}

Output:

Mean is 4.084
Median is 5.2
Mode is 2.5
