.class expected error when passing array to function

public class AssignmentChapter8
{
    public static void main(String[] args)
    {
        int randomNumbers[] = new int[100];
        int oddCount;
        int evenCount;

        for(int x = 0; x < randomNumbers.length; x++)
            randomNumbers[x] = (int)(Math.random() * 25);

        for(int y = 0; y < randomNumbers.length; y++)
            if(randomNumbers[y] % 2 > 0)
                oddCount += 1;
            else
                evenCount+=1;


        int oddNumbers[] = getOddNumbers(oddCount, randomNumbers[]);
        int evenNumbers[] = getEvenNumbers(evenCount, randomNumbers[]);

        System.out.println();
        System.out.println("The list of odd numbers is:");
        System.out.println();

        for(int a = 0; a < oddNumbers.length; a++)
            System.out.print(oddNumbers[a] + "\t");

        System.out.println();
        System.out.println("The list of even numbers is:");
        System.out.println();

        for(int b = 0; b < evenNumbers.length; b++)
            System.out.print(evenNumbers[b] + "\t");
    }
    public static int[] getOddNumbers(int oddCount, int randomNumbers[])
    {
        int oddNumbers[] = new int[oddCount];
        int counter = 0;

        for(int x = 0; x < randomNumbers.length; x++)
            if(randomNumbers[x] % 2 > 0)
            {
                oddNumbers[counter] = randomNumbers[x];
                counter++;
            }

        return oddNumbers;
    }
    public static int[] getEvenNumbers(int evenCount, int randomNumbers[])
    {
        int evenNumbers[] = new int[evenCount];
        int counter = 0;

        for(int x = 0; x < evenNumbers.length; x++)
            if(randomNumbers[x] % 2 < 1)
            {
                oddNumbers[counter] = randomNumbers[x];
                counter++;
            }

        return evenNumbers;
    }
}

I'm new to java and have been trying to create a program to generate 100 numbers and sort odds and evens. The program has even giving an .class expected error no matter what I do. Any help would be appreciated.

As Peter Lawrey stated, you don't need the brackets on the function calls. There are also a few other compilation errors. First, it looks like you have a copy/paste error in the getEvenNumbers function. Inside the for loop oddNumbers should be evenNumbers.

You also need to initialize the ints oddCount and evenCount (probably to 0).

When referring to an array as a whole, don't use the [] with the variable name. Change

int oddNumbers[] = getOddNumbers(oddCount, randomNumbers[]);
int evenNumbers[] = getEvenNumbers(evenCount, randomNumbers[]);

to

int oddNumbers[] = getOddNumbers(oddCount, randomNumbers);
int evenNumbers[] = getEvenNumbers(evenCount, randomNumbers);

The [] is not needed in this line instead of

int randomNumbers[] = new int[100];
// and 
int oddNumbers[] = getOddNumbers(oddCount, randomNumbers[]);

write

int[] randomNumbers = new int[100];
// and
int[] oddNumbers = getOddNumbers(oddCount, randomNumbers);

The [] is part of the type, not the name.
