Question

I'm having trouble with this Java coding. There are errors in my code but I don't know how to resolve them.

//Import Scanner class
import java.util.Scanner;

//Import Random class
import java.util.Random;

//Driver class/program
public class ProcessingArrays{

//Main method
public static void main(String[] args){

//Create new instance of Scanner object
Scanner keyboard = new Scanner(System.in);

//Ask user for number of double values
System.out.println("How many double numerical entries do you have?\nenter in digits ex: 3");

//Declare variable sizeOfArray of type double
//Save user input sizeOfArray
int sizeOfArray;
sizeOfArray = keyboard.nextInt();

//Create array of size sizeOfArray
double[] randomArray;
randomArray = new double[sizeOfArray];

//Create new instance of Random object
Random rand = new Random();

/*Use for loop to generate and assign random
double values to randomArray*/
for(int i = 0; i < sizeOfArray; i++){
randomArray[i] = rand.nextDouble();
}

//Invoke sumOfArrayValues method
sumOfArrayValues(double[] randomArray);

//Invoke aveMaxMin method
aveMaxMin(double[] randomArray);
}

//Sum method with an array as input and a double as output
public static void sumOfArrayValues(double[] randomArray){
//Declare variable sum of type double
double sum = 0;

//Create for loop to sum the values of the array
for (int i = 0; i < randomArray.length; i++){
sum += randomArray[i];
}

//Print the number of entries
System.out.println("The number of entries in the array is: " + randomArray.length);

//Print the sum of the entries
System.out.println(sum);
}

//Average, Maximum, Minimum Method
public static void aveMaxMin(double[] randomArray){

//Declare variables of type double: sum, average, max, and min
double sum = 0;
double average = 0;
double max = 0;
double min = 0;

//Use a for loop to calculate the sum of the array values
for (int i = 0; i < randomArray.length; i++){
sum += randomArray[i];

//Use if, else-if statements to find min and max values
if (randomArray[i + 1] > randomArray[i]){
max = randomArray[i + 1];
}

else if (randomArray[i + 1] < randomArray[i]){
min = randomArray[i + 1];
}
}

//Calculate and print average of array values
average = (sum / randomArray.length);
System.out.println(average);

//Print max and min values
System.out.println("The maximum value in the array is: " + max);
System.out.println("The minimum value in the array is: " + min);
}
}

The errors are: (See image attached)
