Java HW Help!!

Under the com package create an ItemSale class. It should have the following class variables: saleld (int), itemName (String), purchase Price (double), sellPrice (double) items Sold (int). Create an Item Demo class with a main method. In the main method, create three items. Make only two items have the same itemName. Create the following methods: Create a method called getMostExpensiveltem that passes in three ItemSale objects and returns the name of the most expensive item (Note: if there are two items that have the same price, it will just return the name of the first item). Create a method called getLargestProfititem that passes in three ItemSale objects and returns the name of the item that has the highest profit. To calculate profit, it's (sellPrice-purchasePrice) * itemsSold. (Note: if there are two items that have the same profit, it will just return the name of the first item). Test all methods in the main method. Create a method called getProfit that passes in the name of the item and three ItemSale objects. It will return the total profit for all items matching that itemName. Profit calculation is the same as the calculation in the previous method. Conditional Operators, Objects and Classes!
