    Default Confused with Arrays

    This is what i have so far...
    import java.util.Scanner;
     
    public class Array
    {
    	private static int getProduct;
     
    	public static void main(String[] args)
    	{
    		int[] array1 = {1, 3, 5};
     
    		System.out.println("Product test: ");
    		System.out.println("input parameters; ");
    		System.out.println("product: ");
     
    	}
    }

    I'm having trouble with arrays and my teacher did a horrible job explaining it. I went and read Java how to program in chapter 7, but it did not help me out that much of understanding it. I'm confused and don't know which array method to use or where to begin on figuring this out.
    getProduct:
    product calculates the product of a series of integers

    Sample Output:

     

    Product test:
    input parameters; 1, 3, 5
    product: 15
    input parameters; 1, 3, 5, 7
    product: 105
    input parameters; 2, 3, 4, 5, 6
    product: 720

    Is this program meant to take user input from the console and place the numbers into an array?

    This should help you move forward:

    import java.util.Scanner;
     
    public class Array
    {
        private static int getProduct;
     
        public static void main(String[] args)
        {
        	System.out.println("Product test ");
        	System.out.println("Enter numbers: eg 1,2,3");
     
        	Scanner sc = new Scanner(System.in);
            String numbersStr = sc.nextLine();       
     
            String[] array;
            array = numbersStr.split(",");        
            System.out.print("input parameters: ");
     
            for(int a = 0; a < array.length; a++){
            	System.out.print(array[a] + " ");
            }
     
            //System.out.println("product: ");
     
        }
    }

    Default Re: Confused with Arrays

    getProduct is suppose to to get an unspecified number of integers that is passed to the method using a variable-length argument list, and also returns the product of the integers.

    also thx for putting my method in that code box. How where u able to do that? I'm new to the forums.
