Bubble Sort Int Array Problem

the error says int cannot be deferenced at java line 11
here is the code.
how do i fix that?
Code :
public class SortInt
{
    public static void sort(int cases[])              //Sorting fuction, the array of nums is passed to it
    {
        int temp;                                    //a temp var is need to swtich the values in the array
 
        for(int i = 0; i < cases.length - 1; i++)        //Start of the bubble sort, you need to take one away from
        {                                               //the legnth of the array b/c you dont need to go throw the
            for(int j = 0; j < cases.length - 1; j++) //array that many times. Also if it whould go passt the end of
            {                                           //the array in the second loop wich whould not been good.
                if(cases[j].compareTo(cases[j+1]) > 0)               //This part checks to see if the number before it is bigger
                                                                    //You must use the compareTo() method of a string
                {                                       //Note: chage the < opprator to > to sort from samllest to lagergets
                    temp = cases[j];                    //Sotres the value of nums[ii] in the temp var for use latter
                    cases[j] = cases[j+1];              //puts the value of the bigger number where the lesser one was
                    cases[j+1] = temp;                  //puts the value of the lesser var back in the array where the
                }                                       //biger one was.
            }
        }
    }
 
    public static void main(String[] args)
    {
         //declares an array to be sorted
         int[] cases = {200000 , 300000 , 100000 ,400000 , 500000 , 750000 , 1000000,
		 1 , 2 , 5 ,400 ,500,750, 1000 ,
		5000 , 10000 , 25000 , 10 , 25 , 50 , 75,
		100 ,  50000 , 75000 };
 
         System.out.println("Before sort():\n");
         for(int i = 0; i < cases.length; i++)      //for loop to show all the values of the array
         {
             System.out.println(cases[i]);          //uses the for loop index var to slect an array entreay
         }
 
         sort(cases);                               //sends the array to the sort() fuction
 
         System.out.println("\nAfter sort():\n");
         for(int i = 0; i < cases.length; i++)      //for loop to show the realostes of the sorting
         {
             System.out.println(cases[i]);
         }
    }
