Beginner-Friendly Java Project: Banking Application

[@CompSciCentral]

First!

[@radhakrishna-ce7dg]

Wonderful explanation man. Pure beginner's project. It boosts their confidence. I really appreciate your time and keep doing projects. we support you. Good luck

[@RameenFallschirmjager]

Java always had and has a special in my heart. I'm always looking for ways to become more intimate with this language! I need more projects to do so!

[@CompSciCentral]

Same. Java was the first language I learned. Although I'm getting into web development and transitioning to JavaScript and I really love that too! I'll post more projects in the future. Take care! :D

[@RameenFallschirmjager]

@@CompSciCentral Web is such a plague! Everyone goes into web development! Personally I don't see much room for creativity in web. I like java and similar languages more. You can create more sophisticated, elaborate systems.

[@CompSciCentral]

@@RameenFallschirmjager That's an interesting perspective. I don't actually have any development work experience yet so I really wouldn't know what to expect.

[@RameenFallschirmjager]

@@CompSciCentral Let your imagination loose! Don't copy from the mainstream Clichés. Computers used to be fun and a tool in the creative hands to make whatever they found amusing. Now these so called programmers and hacker just make another shitty social network, or a stupid good for nothing website! My dream to make elaborate, sophisticated worlds and I'm working on skills which contribute to this end.

[@mwanikimwaniki6801]

Bro. This is it. Your site is really giving me key insight on how to use my Java skills

[@CompSciCentral]

That's awesome, I'm happy to be of any help! When you learn to code, a world of possibilities opens up to you! Keep it up!

[@stopthat4527]

Great little tutorial, that's just the right amount! Loved it! Re-enforced some of the fundamentals for me, and made them clearer. One question if you have time to answer, if not, no worries: I was curious why you used this in the do loop: char option1 = scanner.next().charAt(0); option = Character.toUpperCase(option1); Instead of say... char option = scanner.next().charAt(0); option = Character.toUpperCase(option); Obviously it doesn't work the second way, but I'm not sure why? It seems like we're just re-assigning it in the next line, so not sure why the 'variable 'option' already defined in scope gets called? Thanks!

Thanks a lot man! I was just curious, do you know how to put projects from Java on your resume? For frontend stuff its easy, I just host the website and put it there, but for something like eclipse I don't get what to do lol.

[@CompSciCentral]

Hey Eshgod! I’m glad you enjoyed this tutorial! To share this on your resume, I would publish the code in a repository on your GitHub and describe the project on your resume with a link to the github repository. That’s how I did it, I hope that helps!

[@eshw23]

@@CompSciCentral Awesome makes sense

[@DucNguyen-sd4mn]

i have a question. For each of the functions, why don't you use while (amount !=0) instead of if statement?

[@CompSciCentral]

You can do that! There are often multiple solutions to the same problem when programming.

[@deepmgn]

Hi. Thanks for sharing this. I just have a question. If we customize this using Java FX with better user interface etc and make an offline desktop app etc, will showcasing this project be good enough to get a java developer job at tech companies or will they need something more large and complex than this to impress them?

[@CompSciCentral]

I think you would need something a little more complex. What I like to do to see if I'm qualified for a job is to find a listing (or a few listings) for the job I want and then look at the technologies that they're looking for in a candidate. Likely you will need to know Java OOP inside and out, and a few other things depending on the role. I hope this helps! Good luck!

[@AD-mg5ut]

Brilliant tutorial! Are there any intellectual property warnings we should be aware of?

[@CompSciCentral]

Nope! I’m glad you enjoyed the tutorial, use the code however you like.

[@AD-mg5ut]

@@CompSciCentral amazing! I put it on my GitHub. And there were additions by a ghost author. Where should I start with computer science, data, electronic engineering etc? Where do I go to intuitively develop my own code

[@shantyleacaliph3460]

As a beginner, I was hoping to see a video that would walk me through the coding process, not just give me the script. I am wanting to know how and "Why" you used the scripting that you did, or else, you are just giving me the answer to the process, and thats it.

[@Ruin3.14]

You need a understanding of Java structure before watching this. This isnt a introduction to Java video....

[@bhautikdudhat9179]

Can anyone please help me, what should I write on my resume about this project description

[@CompSciCentral]

Write the name of the project “Java Banking Application” then list details about it either as bullets or a few short sentences. -Created multiple OOP classes to represent bank account object -Bank object can deposit, withdraw, check balance, view transactions, and calculate interest -Instantiated new bank account in main method with user credentials Also, make sure to write a cover letter when applying to roles.

[@hf.1906]

In my Java class we were taught to either write public or private for the methods and instance variables, is that an unnecessary step or is there a specific reason you did not write that for this project?

[@CompSciCentral]

Hey Hilda! Thanks for commenting. It's actually been a while since I've coded in Java but I believe when you don't specify 'public' or 'private' the method/instance is presumed to be public. Otherwise it wouldn't be accessible from other classes. But feel free to ask your Professor to double check because I'm not 100% sure. Have a great day!

[@narc440]

I'm an AP comp sci student in Java. I was taught that you do have to specify either public or private for variables and methods in classes that aren't your main class.

[@enisluis1234]

Hello i have done something similar to this but a little more complex with more classes and more methods. I want to ask something if you know about it, i am worried about work because someone offered me a job as a programmer, but this is as far as i know (oop i mean), for the moment i turned it down because i have school, but after that do u think that this knowledge is enough to get started?

[@CompSciCentral]

That’s awesome that you already have an offer. To answer your question I would say that it depends on the company as they will have different requirements. But it may be enough for an internship or entry level developer position. I’ll be making more videos with tutorials like this in the future if you want to keep learning.

[@gibymolthomas6168]

Hi, While calling the main function I am unable to get the Customer name and customer id. Instead of that I am getting NULL for both id and name. can u please help me out

[@CompSciCentral]

Hey Gibymol! Thanks for commenting. It's hard to determine what's going wrong unless I see your code. Feel free to put it on Github and share the link here and I'll take a look at it. You could also take a look at my code for this project (there's a link in the description) and compare it to your own. I think it would be a good exercise!

[@nicholasnervais331]

Hi good day, i was wondering about the account aspect... can customers create a new account via the interface/menu they first see? and how would i go about doing that

[@CompSciCentral]

Hey, Nicholas! Sorry for the late response. It's absolutely doable. There must be prompts in the main class that asks the user for their name (and either asks for an ID or automatically assigns one), and then inserts those variables when instantiating the object (the bank account). I hope that helps! Have a great day!

The previous transactions will be gone when restarting the program right? It would be cooler (in mine opinion) if they would be saved

I totally agree, that would be cooler. I think this could be accomplished if the program were attached to a database. Then each user and their transaction information could be stored. I'll try and do something like that in the future!
