DUKE

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

Hi this is my Duke program! It's

Fun 👍
Easy to use
text-based

Steps to use:

Download from here
Run
Use!

Features:

Managing tasks
GUI

Sample code main :

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

LGTM! The code looks clean and easy to read, with most of the comments being nit-picky 😂 Think that the logic can be a bit more simplified in Parser, and that some javadoc is missing. Excellent code, keep up the good work!! 👍

Should java related imports come before duke?

I think perhaps can consider importing individual classes instead of using wildcard import!

Maybe can consider using enum for this!

Feel like the condition when the DukeException is thrown should be specified here :))

Should there be a whitespace before the curly braces?

+            }
+            return new AddCommand(first_word, remaining);
+        }


Perhaps we can use enum here to simplify the logic here! Also, personally I fell that all the try-catch statement here can be abstracted to other class method e.g. createDone() etc. to prevent arrowhead style code, and that one single catch for ArrayIndexOutOfBoundsException could be used for the entire method. Don't know if I articulate my idea in a very accurate way 😂

Should case be on the same indent level as switch?

LGTM! I think the code is very clean and easy to read and there is very clear abstraction between classes. Well done!

I think you should import package by package, for example import duke.TaskList rather than using import duke.*

src/main/java/Command.java

+public abstract class Command {

+    public abstract boolean isExit();


You might want to consider setting isExit to False in the abstract, then only changing it to True when it is an ExitCommand. This way you do not have to constantly check what Command it is

Gradle run and shadowJar tasks are not functioning as intended. This should be fixed for ease of use and to create a new JAR release. Let's edit the build.gradle for proper main class declaration. Also,let's fix any checkstyle errors that might inhibit the build process.

There are some left over code from before GUI was implemented. These leftover code that is not used should be removed to improve code quality and readability. Let's check through the code and remove any unused methods or other files.
