Thread: Please help with array code

These are the requirements for my assignment along with the outline of the main method and examples of the desired output. Below that is my actual code which I have written but the output doesn't match what is desired

For this assignment you will be reading in an int number that tells
you how many two-digit pseudorandom random int numbers to put into an array.
You will call a method "genRandom" to generate psuedorandom numbers and put
them into an array. The header of the genRandom method is

public static void genRandom(int num, int[] intArr, boolean DEBUG, int SIZE_ARR,
Random rand, int INT_LOWER_LIMIT, int INT_RANGE)

Once the array has been filled we will call a second method to print out the
data in the array. The header for this method is

public static void printData(int num, int[] arr)

After the entire array has been printed out, you will call a method that
computes the sum of the elements of the array. The header for this
method is

public static int sumData(int num, int[] iArr, boolean DEBUG)

After the returning from the sumData method you will need to print out the
int returned by the sumData method.

Then you will call a method that will print only the even numbers stored in
the array. The header for this method is

public static void printEven(int num, int[] iArr, boolean DEBUG)

Then you will call a method that will print out the odd numbers stored in the
array. The header for this method is

public static void printOdd(int num, int[] iArr, boolean DEBUG)

Then you will call a method that will print out the reverse of the used part of
the array. The header for this method is

public static void printReverseArray(int num, int[] iArr)



main method
------------

To create pseudorandom ints we will be using a standard class called Random.
You declare and instantiate a Random object with the following code. For the
Random class to work properly you will need to import java.util.Random .

final long SEED = 8675309L; // Arbitrary"seed" to be used
// in this assignment

final int INT_LOWER_LIMIT = 10; // Lower limit of pseudorandom ints
// for this assignment

final int INT_RANGE = 90; // Range of pseudorandom ints for this assignment

Random rand = new Random(SEED); // Declare and instantiate object rand

Declare SIZE_ARR, a final int equal to 30.

Declare an array of ints with size equal to SIZE_ARR:

int[] intArr = new int[SIZE_ARR];

Declare DEBUG and all other final named constants. See below.

Declare and instantiate the Random object rand.

Declare all necessary variables.

Read in the value of num, the number of pseudorandom numbers to be generated.

Call the genRandom method

Call the printData method

Call the sumData method

Print our the result of the sumData method

Call the printEven method

Call the printOdd method

Call the printReverse method

Odd numbers in the array are:

DEBUG
The nummber in array location 0 is 95.

DEBUG
The number is odd.

intArr[0] = 95

DEBUG
The nummber in array location 1 is 28.

DEBUG
