Get Inverse Of 2 x 2 Matrix With Proper Error Checking - Java Quiz Question

Write a program to get the inverse of 2 x 2 matrix with proper error checking.

Input (Two Dimensional matrix)	Output (Two Dimensional matrix)
`20 45 2 5`	`0.5 -4.5 -0.2 2.0`
`-1 2 3 -7`	`-7.0 -2.0 -3.0 -1.0`
`25 20 5 4`	`null`
`{}(EMPTY ARRAY)`	`null`
`null`	`null`

	
		class AdvanceInverseOf2X2Matrix	
			{    public static void main(String s[])
    {
        int input[][] = {{20, 45}, {2, 5}};
        double output[][] = getInverse(input);
        if (output != null) {
        for (double[] array1d : output) {
        for (double element : array1d) {
        System.out.print(element + "   ");
        }
        System.out.println();
        }
        } else {
        System.out.println("Inverse of matrix should not be performed due to invalid input data.");
        }

    }
 
			

				public static double[][] getInverse(int matrix[][]) { 

				//Write code here to get the inverse of given 2 x 2 matrix and return the result. 

				} 

				 

				public static int getDeterminant(int matrix[][]) { 

				int result = 0; 

				//Write code here to get the determinant of given 2 x 2 matrix. 

				return result; 

				} 

			}
