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

Expand Post »
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$

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

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

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

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

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

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....

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

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 ?
