After Mingo's negation, Java Thai again out new works! Mingo Access Code!

The last time to do that system is SWING+JDBC realization, helpless by Ming elder brother a negation, database connection completely can not reflect the function of data structure, hey, this is to the younger brother pressure ah. People without pressure not out of oil, after 10 days of efforts, finally Li Gang's address book updated to 1.1 version!

The following are the design ideas, as well as specific reports

————————————————————————————————————————————————————

An experimental report on Li Gang's address book design

--Jiang Jintai 1132 class

1) Topics

Li Gang is a love toss of the people, of course, love tossing the person has a dream, he wants to be China's cover time. No, now personal friends more information, complex, he wanted to make a personal Address book production management software. Just this semester to learn the data structure class, so he is ready to use the data structure knowledge to achieve. and consider using a doubly linked list as a data structure. and established the preliminary requirements:


(1) Each friend information includes name, gender, address, zip code, age, telephone, QQ, account number, birthday, etc.


(2) As a complete system, should have a friendly interface and strong fault tolerance

2) Demand Analysis

First, transport to the relevant data structure Foundation--Double linked list

Second, can not move the database, that is, the need to use the file IO stream, the character information recorded in the relevant files

Third, need to have the basic function of adding and deleting

Four, good interactive interface

Four, better fault-tolerant ability

3) Conceptual Structure design

Characters ={ name, gender, address, zip code, age, Phone, QQ, account number, birthday }

Name is code, phone is code (key)

4) Logical Structure design

One, doubly linked list, specific difficult to achieve, so to develop Lenovo, double-linked table tree--Tree as a collection of data structure (hereinafter referred to as the tree set).

Second, the information is stored in the tree set.

Third, the tree collection to the data file

Iv. file, change data, file---Tree set

5) Physical Structure design

First, the establishment of the data file

Second, the construction of the character class

Third, the construction tree integration as a collection of character classes

Four, well-structured interactive interface

6) system implementation and testing

Simple one package, addresslisttreeset for tree set

The person class contains a collection of character attributes

Showjframe Main interface

DAT is a file for storing people's information

This is the main interface, the left is a jlist surname navigation, below is a function panel, where, by name lookup and by phone number lookup will read the name box and the contents of the phone box

Clicking the navigation box jumps

Add button function, if any one input is empty, will error, support input do not know

Click Down on the bar, click Search by name will be queried

Phone numbers don't do it.

Delete effect, select any, delete, read data after end

7) Advantages and disadvantages self-evaluation

First, AddressList1.1 lost the 1.0 version of the interface beautification, but also reduce the layer of the interface

Second, the lack of modification function, because the implementation of more complex, time is not allowed, so.

Three, I do not make the best use of time, always programming at night

Four, graphical interface and data structure part of the content is not solid, do often want to read, see CSDN, lack of efficiency

8) code show, put code past! Mingo Access Code!
