My school assignment keeps generating errors

[BenH]

Hi.

The assignment that I am supposed to code for school keeps generating errors. First, the errors I get are in the InventorySort class. These are the errors:

Line 22: bad operand types for binary operator '>'
Line 24: error: incompatible types
Line 26: error: incompatible types

Then I get errors on the InventoryAdvanced class that says:

Line 21: Error: ".class" expected.
I tried removing the [] then it generated even more errors

Can someone help me fix these? I need to get this assignment in ASAP.

Classes:

	public class InventoryAdvanced {


	public static void main(String args[]){

		int size = 4;

		InventoryDefine swordstone = new InventoryDefine("Sword In The Stone Movie", 1, 10,13.00);
		InventoryDefine hercules = new InventoryDefine("Hercules", 2, 20, 5.00);
		InventoryDefine mermaid = new InventoryDefine("The Little Mermaid", 3, 30, 10.00);
        InventorySort methodCall = new InventorySort();

   		InventoryDefine inventoryArray = new InventoryDefine[3];

   		inventoryArray[0] = swordstone;
   		inventoryArray[1] = hercules;
   		inventoryArray[2] = mermaid;

   		//Call the sort method
   		methodCall.Sort(inventoryArray[]);

   		//Display the sorted array
   		for (int i = 0; i < size; i++){

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

   		}


	}
}

public class InventoryDefine {

	//Define the variables
	public String inventoryName;
	public int inventoryNumber;
	public int inventoryStock;
	public double inventoryPrice;

	//Declare the constructor
	public InventoryDefine(String name, int productNumber, int productStock, double productPrice){

		this.inventoryName = name;
		this.inventoryNumber = productNumber;
		this.inventoryStock = productStock;
		this.inventoryPrice = productPrice;

	}

}

		size = 4;

		for (a=1; a < size; a++)
			for (b=size-1; b >= a; b--){

				if(array[b-1] > array[b]) {

					t = array[b-1];
					array[b-1] = array[b];
					array[b] = t;

				}
			}


}

}

Can You explain argument of this method?

public void Sort(InventorySort array[])

[BenH]

Hey!

That method is supposed to sort the array. The reason why the class name acts as the identifier is because that is what my instructor told me to do. I cannot seem to get it to work for some reason. I posted all the errors up on my previous post. I put the [] to show that the parameters take an array.

But what objects is it supposed to be sorting? Certainly not an array of itself, right? Perhaps you want the method to accept an array of InventoryDefine objects?

never heard about the interface comparable, then look at some examples: Object Ordering (The Java™ Tutorials > Collections > Interfaces)

I am using the Bubblesort algorithm to sort the array which you can find in the InventorySort class. I am sorting the array itself. Is there another way of making this work?
