    "Missing return statement" is self evident. You have a non-void method which does not have a return statement. "Yes it does" you cry. Perhaps you have an if statement in the method which means that there are two or more alternative paths through the code and one of those paths does not hit a return statement. Time to debug your code.

    Hi,
    Problem is in the bellow code
    // Get inventory value
    public double getInventoryValue() {


    Inventory myInventory = new Inventory();


    myInventory.addToInventory(new DVD(1, "Remember the Titans", 5, 14.95));

    // Print out the inventory total value
    System.out.println("Total value of inventory is: " + myInventory.getInventoryValue());

    }
    that should return a double value.
    eg.
    // Get inventory value
    public double getInventoryValue() {


    Inventory myInventory = new Inventory();


    myInventory.addToInventory(new DVD(1, "Remember the Titans", 5, 14.95));

    // Print out the inventory total value
    System.out.println("Total value of inventory is: " + myInventory.getInventoryValue());
    return myInventory.getInventoryValue();
    }
