All are here for helping each other so please do not tag anyone firstly

The error is saying you cannot convert a String array list to integer array list for this you have to parse your string to int by using loop like this

//      creating String array list
        String[] stringlist = {"1","2","3","4","5"};
//      Creating new integr array list of size 5
        int[] integerlist = new int[5];
//      Using for loop for parsing the integer from string
        for (int i=0;i<stringlist.length;i++) {
//          parsing integer by Integer.parseInt(string)
            integerlist[i]=Integer.parseInt(stringlist[i]);
//          printing converted int
            System.out.println(integerlist[i]);
        }

In this you can see I am using Integer.parseInt() method to parse string in to integer
Hope this helps you
