Sort array of objects

Hey there, I'm looking in to using the sort method for arrays. I have a class of grocery items and 3 arrays of 25 items. I need to sort one by the aisle number, another by price, and the last alphabetically. Can I do this with my class or do I need to alter it in some way or should I write my own sorting method?

Code:

---

class GroceryItem{
       
        public String name;
        public double price;
        public int stockNumber, orderNumber, row, numItems;
        public long SKU;
        Random generator = new Random();
       
        public GroceryItem(String name, String price, String row){
                this.name = name;
                this.price = Double.parseDouble(price);
                this.row = Integer.parseInt(row);
                this.stockNumber = generator.nextInt(50);
                this.orderNumber = generator.nextInt(20);
                this.SKU = generator.nextInt(1000000);
        }
        public void purchase(){
                this.stockNumber -= 1;
                this.numItems += 1;
        }
}

Thank you for any help you have to offer!
