For instance, if you were doing the ToDo list application If you are making a To Do list application, you might make the main interaction loop that asks: "what would you like to do [1] add a to do list item, [2] cross off an item [3] show all the items" if the user types in "1", they would be asked "Enter the item text", and then the text would be saved. if the user types in "2", they could be shown a list of items from the todo list (you'll want to make a list of some kind!), with individual numbers, and asked "which item would you like to cross off". The user would then enter the number of the item, and that item would be moved from the todo list to the crossedoff list (two lists!!) if the user types "3", the list of items would be printed, along with their status (crossed off, or to do) All this can happen in just one class for now! Get basic interaction loop going, use at least one class, and must have multiple methods that are called. . Make at least 1 package: ui Make at least one class named appropriately for your application Make a main method that gets things going Construct an object (Note: this should probably happen within your main method) . Declare a field and use it (not necessarily at the same time!) . Pass a parameter Use a local variable . Return a value and use it Use a condition, AND a loop Make a call graph from your main method Draw the flowchart for a method with a condition or a loop Get user input, and reflect it back to the user . Use the debugger
