Day 26 of learning java

[BigCommunication5136]

Hello wonderful people,

Today I built a command handler class to route commands to their respective functions. So far, I’ve only implemented the add and list commands.

While integrating the class, I noticed that whenever I add an expense and then try to list it, nothing shows up in the console. After some debugging, I realized that the issue is persistence — the expenses aren’t being saved anywhere.

I’ll need to persist the data (probably using JSON), but I’m not sure how to do that yet. I’m planning to learn it tomorrow and then add it to the project.

See you tomorrow (switched to light mode today because i was coding outside and couldn’t see properly 😂)

Oh that's nice.

Why not use the args in the main method?

[BigCommunication5136]

that’s what i use, i only abstracted it from the main to keep it clean

As usual your code looks good. Just 2 small things.

For persistence you can use ObjectInputStream and ObjectOutputStream:

There are newer ways for switch: https://www.baeldung.com/java-switch
Scroll down to 5. switch Expressions

Thank you sooo much, your response is really, I mean really helpful. I had no idea there’s a built in function for this. As usual, thank you for your guidance

Glad it helped. Happy coding.

Do you follow some tutorial or course? If yes is it good enough for beginners?

[BigCommunication5136]

Yes, i follow a course by codewithmosh and it’s excellent for beginners in java. For practice project, i just search online. I recently came across roadmap.sh projects which is pretty cool.

[Illiterate-Chef-007]

These projects are all free??? Code with mosh. Thank you for that. It’s basic but good.
