Question

ToDoItem is a class that represents a task that needs to be done.
A has a description, priority, category and dueDate. These instance variables are described in more detail below.
Description and category should be of type String. The description should never be empty and it should probably be fairly short for display purposes. You should provide a String constant, UNFILED or NONE perhaps, to be applied to objects that haven't been given a category. Provide a javadoc comment for your public constant.
Priority should be a number between 0 and 9 where 9 is the highest priority and zero is the lowest. that aren't given a priority will automatically have a priority of 0 because of the way Java initializes instance variables. No should have a priority that is not in this range. This should be explained in the documentation. You should assign a priority of zero if a user enters a priority that is outside this range. Can you write static method that prompts the user and reads the data for objects from a Scanner that is passed in as a parameter.?The method should create and return a new using the data it reads in.
public static ToDoItem inputToDoItem( Scanner in)
The method should read one field per line in the order
1.description
2.category
3.date
4.priority

Explanation / Answer

public class ToDoItem {
    /* If description is empty, assign UNFILED constant to description */

    private final String UNFILED = "Default";
    private String desciption;
    private String category;
    /* Automatically initiates priority instance varaible to 0 when object initiated.*/
    private int priority;
    private String dueDate;

    ToDoItem(String description, String category, String date, int priority) {
        if (this.category == null) {
            this.category = UNFILED;
        } else {
            this.category = category;
        }
        this.desciption = description;

        this.priority = priority;

    }

    public static ToDoItem inputTodoItem(java.util.Scanner input) {

        description = input.nextLine();
        while (description.length() < 1) {

            description = input.nextLine();
        }

        System.out.print("Enter Category    : ");
        category = input.nextLine();

        while (priority < 0 || priority > 9) {
            try {

                priority = Integer.parseInt(input.nextLine());
            } catch (NumberFormatException e) {

            }
        }
