    Default How do I write a passing array program that determines if the value...

    How do I use a method that takes an integer array argument, and determines if the value Of the element of the array is even, and that prints the value. It also requires that I use a for loop to iterate through The array. Incorporate this method in an application that passes the array, int NUMS [] {12, 7, 52, 3, 15, 27, 6, 14, 25, 2}

    How do I know that this is a passing array?

    // Programmer: David_Rivera
     
     
    public class isEven 
    {
    	public static void main( String[] args )
    	{
    		int[] Nums = {8, 16, 9, 52, 3, 15, 27, 6, 14, 25, 2, 10 };
    		for (int isEven = 0; isEven< Nums.length; isEven++) 
    		    if (Nums[ isEven] % 2 == 0)
    		    {
    			   System.out.printf( "Even %d \n", Nums [isEven]);
     
    		}
     
     
    		int[] array = {8, 16, 9, 52, 3, 15, 27, 6, 14, 25, 2, 10 };
     
    		System.out.println("Effects of passing reference to entire array:\n" + "The values of the original array are:" );
     
    // output original array elements
    for ( int value : array )
    System.out.printf( " %d", value );
    	modifyArray( array );
    System.out.println( "\n\nThe values of the modified array are:" );
     
    // output modified array elements
    	for ( int isEven : array )
    	System.out.printf( " %d", isEven );
     
    	System.out.printf( "\n\nEffects of passing array element isEven:\n" +
    		"array[3] before modifyElement: %d\n", array[ 3 ] );
     
    	modifyElement( array[ 3 ] );
    	System.out.printf( "array[3] after modifyElement: %d\n", array[ 3 ] );
     
    }
    public static void modifyArray( int[] array2 )
    {
    for ( int isEven = 52; isEven < array2.length; isEven++ )
    	array2[ isEven ] = array2[isEven] % 2;
    }
    public static void modifyElement( int element )
    {
    element *=1;
    System.out.printf(
    "Value of element in modifyElement: %d\n", element );
     
     
    } // end method modifyElement
    } // end class isEven

    Allowed? Sure, nobody can stop you from doing it. But it's considered common courtesy to at least let people know where else you've posted your question. That way we can see what you've already been told. Otherwise we're wasting our time repeating advice or answering questions that have already been answered. People choose to help, for free, in their spare time, so wasting that time is pretty rude.

    I'm sorry if you guys found it rude. Yes I did posted this in that forum but I still haven't received a reply that teaches me that I'm doing the program correctly. I'm being asked;
    use a method that takes an integer array argument, and determines if the value Of the element of the array is even, and that prints the value. It also requires that I use a for loop to iterate through The array. Incorporate this method in an application that passes the array, int NUMS [] {12, 7, 52, 3, 15, 27, 6, 14, 25, 2}
    and no one is helping me know if I'm doing exactly what I'm being ask to do?
