error ';' expected in array defining, ; already used

        return evenNumbers;
    }
}

I have been trying to execute a program to sort variables in arrays, but I keep getting a ';' expected error in the line after declaration of the array where the program is supposed to retrieve an array from a function. Any help would be appreciated.

   int oddNumbers[] = new int[100];

By initializing oddNumbers become an array. when you want to assign values, 

    oddNumbers={elements of array}

Both left and right hand side both should arrays.

May be you should use IDE for coding then it may help you to understand some issues like this.

This is bad syntax (which causes the ';' expected error ):

oddNumbers[] = getOddNumbers(randomNumbers);

The brackets are not needed. You can do this:

oddNumbers = getOddNumbers(randomNumbers);

Besides that, you have plenty of errors:

int randomNumbers[] = new int[100]; // you need the brackets

Your return value in the method declaration is wrong (you are returning an array, not an int):

public static int[] getEvenNumbers(int randomNumbers)
