Please help me to fix my Java code. Its not working. Promise to give like ! !

The_code_is_about_a_to-do_list_application. Keep_track_of_things_to_do, cross_things_off. Possible_features_include_different_views_showing_all_items, or_just_completed_items, or_only_outstanding_items, or_lists_sorted_in_different_ways. The code MUST contain all the 7 steps below (Im struggling to add or make these steps work in my code):

1. The_class_might_be_Item (the_thing_to_do), and_it_may_have_some_fields_like_name , status (doneot_done), and_dueDate. It_would_need_setters_and_getters_for_those_fields (for_example, you_must_have_something_like_setName_and_getName_to_access_and_change_the_value_in_the_name_field). All_methods_would_be_specified_using_REQUIRES/MODIFIES/EFFECTS_appropriately. It_would_also_need_some_internal_implementation, so_in_this_case_it_could_be_something_like_determining_whether_the_item_is_past_its_due_date.

2. Instead_of_just_calling_everything_from_Main, in_the_ui_package, make_a_new_package_called "model", (move_your_Item_class_into_there), and_make_a_second_class "ToDoList". From_your_ui/Main.main construct_the_new_ToDoList,_and_get_the_program_going_from_there. Put_all_the_code_that_was_once_in_Main.main_into_a_new_method (ToDoList.run()), and_move_all_the_helper_methods_from_the_original_class_into_your_ToDoList_class.

3. You_would_also_include_a_class_"TestToDoList"_that_tests_the_ToDoList_class_methods, and_a_TestItem_class, that_has_tests_of_the_Item_methods, ensuring_they_are_behaving_properly.

1. The_ToDoList_class_now_contains_the_interactive_loop_method (called_the "run()" method) that_gets_user_input. ToDoList_has_a_field_that_is_a_list_of_Items,_this_run_method_it_would_let_the_user_add_items_to_that_list. That_means_that_when_the_user_enters "new_item" (the_same_way_we_entered "plus" in_the_logging_calculator)_a_new_Item_would_be_constructed, and_added_to_the_list. The_user_would_be_prompted_for_the_name_of_the_item, and_the_due_date, and_then_those_attributes_would_be_saved_to_the_fields_of_the_Item_using_setters.

2. The_loop_would_also_have_the_option_to_save_the_items_to_a_file. You_would_need_to_define_a_method (save()) that_opens_a_file, loops_through_the_list_of_items_writing_each_Item_in_the_lists's_name_and_dueDate_on_a_separate_line, and_then_closes_the_file. This_behaviour_could_be_launched_when_the_user_chooses_this_option_from_the_interaction_loop, or_maybe_it_happens_automatically_when_they_say "quit". It's_up_to_you_whether_the_user_chooses_the_filename, or_if_it's_just_something_hardcoded_into_the_program_without_telling_the_user_the_name.

3. You_also_need_to_define_a_method_that_reads_each_item_from_the_file (load()). This_would_loop_through_the_lines_of_the_file. For_each_line, you_would_call_new_Item(), and_then_save_the_name_and_due_date_as_the_fields_of_that_new_Item. Each_item_would_be_added_to_the_items_list. This_could_be_launched_either_upon_startup, or_when_the_option_is_selected_by_the_user.

4. You_would_need_to_think_of_two_interfaces -- a_straightforward_combination_is "Loadable" and "Saveable". Each_of_those_would_have_one_method_declared: load() and_save() respectively. The_ToDoList_class_would_then_implement_Loadable_and_Saveable. (Note -- this_is_just_one_arbitrarily_chosen_arrangement -- it's_also_possible_to_make_the_Item_be_the_loadable_and_saveable_class, and_then_load_and_save_would_be_placed_there ... that_may_be_better_for_you_depending_on_your_arrangement.

5. There_would_also_be_tests_for_load() and_save(), testing_just_the_load_method, and_the_same_method, respectively. Testing_file_input/output_involves_checking_that_the_loaded/saved_data_matches_what_was_expected. To_test_that_the_load() method_is_functioning_correctly_you_would_read_from_a_file_for_which_you_know_the_contents, and_then_test_that_the_list_of_objects_contains_objects_that_correspond_to_the_lines_from_the_file. To_test_the_save() method, you_would_populate_a_list_of_objects_with_a_set_of_simple_objects, and_then_write_those_to_a_file. You_could_then_read_all_the_lines_of_the_file_back_in_and_compare_what_has_been_read_back_in_to_a_String_that_looks_the_way_it_should.

6. In_those_tests, you_would_declare_a_ToDoList, so_that_you_could_call_the_helper_methods_on_the_ToDoList (like_the_getters_to_see_whether_the_list_had_the_correct_contents).

7. To_satisfy_this_one_with_the_ToDoList, you_would_likely_want_to_make_a_helper_method_in_the_TestLoadable_class_called "testLoad" that_takes_a_Loadable_as_a_parameter. And_you_would_have_already_instantiated_the_ToDoList_as_a_ToDoList, meaning_you_would_have_instantiated_the_implementation (the_ToDoList, that_contains_the_implementation_of_the_methods). All_testLoad() would_do_would_be_to_call "load()" and_check_what_it_could_reasonably_expect, because_that's_the_only_thing_the_Loadable_type_knows_how_to_do. This_helper_method_would_be_called_from_the_test_method_that_is_testing_loading_of_all_the_Items.
