Lab 7 Java
Declare an array reference variable arrayInt for an array of integers.
Create the array of size 100, and assign it to arrayInt.
Write a method to populate the array with Random numbers between 1 to 25.
Signature of the method is: populateArray( int[] ) which returns nothing.
Call this method from main with arrayInt--> populateArray(arrayInt).
Write a method to print an array. Signature of the method is:
printArray( int[] ) which returns nothing. Print maximum of
ten(10) numbers on a line (see sample output below).
Call this method from main with arrayInt--> printArray(arrayInt).
Write a method that finds the average of the array elements.
Signature of the method is: findAverage( int[] ) which returns the
average to the calling program.Call this method from main with
arrayInt--> findAverage(arrayInt).
import java.util.Random;
public class RandomArrayAverage { public static void populateArray(int arr[]){ Random random = new Random(); for(int i = 0;i public static void printArray(int arr[]){ for(int i = 1;i<=arr.length;i++){ System.out.print(arr[i-1] + "\t"); if(i%10 == 0){ System.out.println(); } } System.out.println(); } public static double findAverage(int arr[]){ double avg = 0; for(int i = 0;i public static void main(String args[]){ int arrayInt[] = new int[100]; populateArray(arrayInt); printArray(arrayInt); System.out.println("Average = "+ findAverage(arrayInt)); } } I NEED HELP ON THE STEPS BELOW FOR THE ABOVE PROGRAM For the lab, complete the 3 steps: 1) Rewrite the problem statement. Draw the IPO diagram - Input, Processing and Output box. The rectangle box which contains the processing, arrows pointing in for each input value and arrows going out for output. https://www.tutorialspoint.com/software_engineering/software_analysis_design_tools.htm (Links to an external site.)Links to an external site. 2) Draw the flow-chart or write down the pseudocode. 3) Write down the method signatures. Know the difference between method signatures and method header. 4) Write down the main method.
