Find The Number Of Words Possible Using An Alphabet Array With Vowels Together - Java Quiz Question

Write a program to get the number of words possible using an alphabets array.
All the vowels in the array should be together.

Input(char Array)	Output
{ 'f', 'r', 'i', 'e', 'n', 'd', 's' }	1440
{ 'r', 'a', 'i', 'n', 'b', 'o', 'w' }	720
{ 'a', 'e, 'i' 'o', 'u' }	120
{ 'a', 'b, 'c' 'e', 'o', 'd' }	144
{ 'n', 'e', 'w', 's' }	24
{ 's', 'u', 'n', 'f', 'l', 'o', 'w', 'e', 'r' }	362880
{}(EMPTY ARRAY)	1

	
		class CombinationsWithVowels	
			{    public static void main(String s[])
    {
        char inputArray[] = {
                        'r',
                        'a',
                        'i',
                        'n',
                        'b',
                        'o',
                        'w'};
        System.out.println("The number of combinations with vowels together and without duplicates are : " + getCombinations(inputArray));

    }
 
			

					public static int getCombinations(char[] array) 

					{ 

				//Write a code here to get the number of words possible using an alphabets array and return result.If required, you can use getFactorial method.  

					} 

				 

					public static int getFactorial(int number) 

					{ 

				//Write a code here to get the factorial of a given number and return it. 

					}  

			}
