Given code:

//Definition of class

publicclassTest {

    //Definition of main class

    publicstaticvoid main(String[] args)

    {

        //Create an array

int[] arr = {1, -2, 4, -4, 9, -6, 16, -8, 25, -10};

        //Call the method average and print the result

        System.out.println(average(arr));

    }

    //Definition of method average()

    publicstaticdouble average(int[] arr)

    {

        //Assign mean to "0.0"

        double mean = 0.0;

//Traverse the array till it reaches the length of the array

        for (int i = 0; i < arr...
