Question

It’s say’s type mismatch…. even if an appropriate type is selected….

I am attaching the code for better understanding….

    public  void calucate()
    {
        int Sum=0;
        arraySumOfRows= new int[20];
        for(int i=0;i<Array1.length;i++)
        {
            for(int j=0;j<Array1.length;j++)
            {
                Sum=Sum+Array1[i][j];
                arraySumOfRows[i]=Sum;
            }

        }

        for(int i=0;i<arraySumOfRows.length;i++)
            System.out.println(Arrays.toString(arraySumOfRows[i]));


    } 

Answer 1

Two problems:

1. arraySumOfRows[i] is an integer and Arrays.toString() expects an array. Just use:

   System.out.println(arraySumOfRows[i]);
   

2. Your inner loop is wrong. I should be:

   for(int j=0;j<Array1[i].length;j++)
