homework(easy): Java GUI/Netbeans using java.util.LinkedList

[collegestuffs]

Hello i have an important homework assignment which is due up on mon 26th and i need a competent java programmer with netbeans expirence. Problem is as follows:

It's a small project and i have basically designed all the forms and buttons needed etc. Now i need someone to link my buttons to classes that use the java.util.LinkedList / Iratator / Serializable functions to just store basic infomations from text fields into a linked list and then into a user specified text file, where i can then search, add, delete etc ..

Its worth about 10% of my final grade, and due on monday so contact me asap ill pay 200$

Why don't you post your project here for us to look at?

[Phaelax]

Quit. Just quit now.

[collegestuffs]

I am familar with creating this type of application without a GUI builder.. homework spec doesnt insist on a GUI builder, but i feel netbeans adds more functionalitys quicker and im sure id get higher grades .

As the netbeans generated code can be quite long i put the netbeans generated code onto this paste bin: http://rafb.net/p/ho7SKr98.html

[iamthwee]

Ok so what's the actual problem? You don't know how to use netbeans?

[collegestuffs]

well this is the first time i have attempted to make a gui with so many menus and a login system with netbeans, and also i am unlear on how to use the:

java.Util.LinkedList for the linked list as i have only used my own code to initate the nodes etc, why re-invent the wheel? :)

and a way to save the list using
serializable (?) or bufferered reader

and then doing searches on it for specific records, maybe implement a grep util i have code for,

all the time i just really need like 10 JTextFields and 6 buttons working it....

[iamthwee]

Ok so you've never used a GUI builder and your project is due monday. Oh dear.

Good luck though!

[collegestuffs]

well i can maybe forget the gui builder and use the classes outside it, but how would i create nodes using the new java.util.LinkedList and present them in a form to save to a text file and manipulate them ?

[collegestuffs]

i managed to knock up a GUI with GUIGenie and it compiles fine in JCreator. now i need someone to help me implement the java.Util.LinkedList and other classes so i can save/read/delete from the linked list !
code is as below:

i have continued with the code above and have tried to implement the linked list re-inventing the wheel ... any ideas guys to make the list work and print into the textfields?

start earlier on your homework next time.
And don't you feel very stupid when you don't understand something you know to be "easy"?
Or are you trying to trick people into doing your work for you by making them think it's "easy" when you think it's not?

If you don't understand the core of your assignment, you shouldn't start adding things you know nothing about either as that won't save you when you fail to turn in a working solution.
