I need help finishing steps 3-7 of the following two JAVA programs.

/**

ArrayOperations class

Chapter 8, Programming Challenge 10

*/

public class ArrayOperations

{

/**

STEP1: getTotal method.

@param array An array of doubles.

@return The total of the values stored in the

argument array.

*/

public double getTotal(double[] array){

double sum=0.0;

for(int i=0; i

{sum+=array[i];}

return sum;}

/**

STEP2: getAverage method

@param array An array of doubles.

@return The average of the values stored in the

argument array.

*/

public double getAverage(double[] array1){

double average=getTotal(array1)/array1.length;

return average;}

/**

STEP3: getHighest method

@param array An array of doubles.

@return The highest value in the argument array.

*/

public double getHighest(double[] array2){

}

/**

Demo program for the ArrayOperations class

Chapter 8, Programming Challenge 10

*/

import java.util.Scanner;

public class ArrayOperationsDemo

{

public static void main(String[] args)

{

// Some arrays of various types.

//step4: Declare an 5-element double array

Scanner scan = new Scanner(System.in);

// Process the array.

//step5: declare an object for array operation

//step6: find the sum of the above array and print the result.

//step7: find the highest value in the above array and print the result.

}

}
