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.

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.
