Duke

“Your mind is for having ideas, not holding them.” – David Allen (source)

Duke frees your mind of having to remember things you need to do. It's,

text-based
easy to learn
~~FAST~~ SUPER FAST to use

All you need to do is,

download it from here.
double-click it.
add your tasks.
let it manage your tasks for you 😉

And it is FREE!

Features:

Managing tasks
Managing deadlines
Reminders (coming soon)

If you Java programmer, you can use it to practice Java too. Here's the main method:

    public static void main(String[] args) {
        new Duke("duke.txt").run();
    }

Hi there, I've looked through your code and your code quality is generally good with some minor improvements to be made 😊.

Good use of OOP is evident, especially through the abstract Task and Command classes. You may also consider adding JavaDocs to the public constructors and methods to ease readability.

Great work on the code overall! 👍

Using input.startsWith("...") may cause some invalid commands to be interpreted as valid commands, e.g. when input starts with deadliner or todoy. Instead, consider using input.split(" ", 2) to get a String[], then check equality against the first element of the String[]. This way, the second element of the String[] also contains all the information you need for your Command subclasses later on.

Since all but one of the commands have isExit() as false, this can be made into a non-abstract method.

Suggested change

public abstract boolean isExit();

public boolean isExit() {

return false;

}

After the non-abstract isExit() is implemented in Command.java, there's no need to override here (and all commands except ExitCommand.java) anymore.

Here should be the only Command subclass where overriding the isExit() method is necessary after implementing it in Command.java.

As before, these repeated checks in the if statements should not be necessary after using input.split(" ", 2) in Parser.java.

Overall a pretty nice job for coding standard! And your OOP design is pretty nice too. Just to remind there can be some improvements for your import and packaging naming.

Keep on your good job! 👍

You may import the duke package inside, and you not really have to specify package all the time.

The assertions feature addresses important assumptions that should hold in the code. A program that terminates the program early once a bug is observed is safer to use as it prevents the error from escalating further. Let's include the assertions feature to define assumptions about the program state so that the runtime can verify them.

Information extraction from input was largely repeated throughout the code, creating long methods and convoluted expressions. Extracting common behaviour into the common Input class reduces the amount of arrowhead style code, makes the expressions easier to understand, and shortens long methods, hence improving the code's readability. Let's improve the code quality so that the code can be more readable.

Branch assertions

Branch code quality

Users might want to delete many tasks or set many tasks as done all in one go, instead of entering a new command line for each task. MassOps allows users to delete multiple tasks or set multiple tasks as done, all in one go. Let's update the functions that delete tasks and set tasks as done to allow them to perform their function on multiple tasks at once.
