Hi I am creating a project in Java using "Data Structures". I have created two classes called ClassID and ClassRecord. ClassID holds transaction information of a access control system (for personnel exiting and entering a secure door) while the ClassRecord allow transaction items to be added into a *.txt file(flat file) as well as to search , print items based on staff 's last name or ID number.

I am able to create a text file containing list of information ......the out put looks like this

Jones (surname)
5456 (ID number)
20 (access control number)
0902 (time of transaction)
1 (entering(1)/exiting(0))
Scott
1539
18
0920
0


My question is how can i read those information into a LinkList and sort the access control transactions by the amount of time,name,and ID number the personnal stayed inside secure premise.

Please any help appreciated.

Well, I'm not sure bout the main problem. However, those kind of stuff could be done by doing the following :

1- make a class that has the ( surename, ID, access number.....) as attributes; if you don't have it yet.

2- on the main class or wherever you read from the file, after reading the info. you store them on a variable of the class type you did in 1.

3- then, add a new Node on a linkedList and store the variable you made in 2 as the Data for this node.

Hopefully that helps,,,
