-# Duke project template
+# Duke v0.9.0
+> *"Be not afraid of growing slowly, be afraid of standing still."* - Chinese proverb
-This is a project template for a greenfield Java project. It's named after the Java mascot _Duke_. Given below are instructions on how to use it.
+Duke offers you a:
+- Hassle free
+- Text based
+- Minimalist
+and completely **offline** experience of planning your tasks!
-## Setting up in Intellij
+## Duke's features
+- [x] Adding and saving tasks
+- [ ] GUI (coming soon!)
+- [ ] Mystery features 😜
-Prerequisites: JDK 11, update Intellij to the most recent version.
+## Setting up Duke
+1. Download it [here](https://github.com/WangGLJoseph/ip/releases/download/A-Jar/ip.jar)
+2. Double-click to run it
+3. Add your tasks
+4. Enjoy **mastery** over your tasks 😆
-1. Open Intellij (if you are not in the welcome screen, click `File` > `Close Project` to close the existing project first)
-1. Open the project into Intellij as follows:
- 1. Click `Open`.
- 1. Select the project directory, and click `OK`.
- 1. If there are any further prompts, accept the defaults.
-1. Configure the project to use **JDK 11** (not other versions) as explained in [here](https://www.jetbrains.com/help/idea/sdk.html#set-up-jdk).
- In the same dialog, set the **Project language level** field to the `SDK default` option.
-3. After that, locate the `src/main/java/Duke.java` file, right-click it, and choose `Run Duke.main()` (if the code editor is showing compile errors, try restarting the IDE). If the setup is correct, you should see something like the below as the output:
- ```
- Hello from
- ____ _
- | _ \ _ _| | _____
- | | | | | | | |/ / _ \
- | |_| | |_| | < __/
- |____/ \__,_|_|\_\___|
+A snippet of the workings of controlling your tasks. Behold, you've got the power!
+ ```java
+ public String finishTask(int index) throws DukeException {
+ if (index > taskArrayList.size()) {
+ throw new DukeException("This task index is not in the task list!");
+ }
+ taskArrayList.get(index - 1).markAsDone();
+ return (sandwich("Congratulations! You have finished this task: "
+ + taskArrayList.get(index - 1).toString()));
+ }
```
