assignment java prog191

applying objectoriented design and analysis to a fictitious case. It describes the various aspects of OOP, such as abstraction, polymorphism, inheritance, and encapsulation. Using the OOP characteristics, I gave the diagram and code for each wallet. Heres an example to help you understand. In the second assignment, introduce a variety of UML class diagrams for objectoriented analysis and design, such as use case diagrams, class diagrams, sequence diagrams, activity diagrams, state diagrams, and flowcharts. I then provided examples of each type of chart I had stated and described. A quick introduction to various design patterns (three types: creativity, structure, and behavior) will be given to the audience, with diagrams utilized to describe the relevant patterns. UML classes are

2 Requirements:

insurance, insurance, term, so I have designed boxes like: ID, Name, Age, allows users to enter all that information into table

function

incorrect input to re-fill

3 UI design:

Begin developing a software system that can suit common demands The initial step is to create a

wireframe to decide what the interface will look like, and then proceed from there Wireframing is a way

to design a website service at the structural level A wireframe is commonly used to layout content and functionality on a page which takes into account user needs and user journeys Wireframes are used early in the development process to establish the basic structure of a page before visual design and content is added

What definitely impresses users most in this program is the clarity of each piece of data Each part is separated not adjacent to each other, which will help users not to be confused between each part

4 Implementation:

4.2 3.1 Main Form:

Tables will be displayed here for each Book data In the book table, manager may add, change, search , and delete goods

Figure 2: Main form looks

Figure 3: Program Structure

Class Book:

Figure 4: Class Book

Class book contains information of Book object including ID, Name, Author, Year Published

Figure 5: GhiFile function

This function is used by me to convert the data in the text Field and then convert it to bytes to save to the BookList.txt file

CORE program:

This is probably the most important part of the program Where the properties of the JFrame window are meticulously modified and specified in code to provide the best user interface

Figure 6: Table setup

In this table part, I declare 4 columns respectively ID, name, author, and year Published In addition, I useJFrame's built-in method, it is addMouseListener, so that the program can perform the action that I specify when clicking on each record in the table

Figure 7: Button SAVE

When it came to the save button, I used the "GhiFile" function above to save the data

Figure 8: Button UPLOAD

When you press the upload button, the program will delete all data in the table in front of you and put the data from the BookList.txt file up This is like refreshing the table and happens almost immediately

Figure 9: ADD button

This ADD button simply, when clicked, will get all the data entered in the text Field, save it in a ArrayList called Book and then print it out to the table

Figure 10: UPDATE button

The update button is similar to how the ADD button works, but the difference is that it will delete right atthe position we pointed at and then replace the deleted record

Figure 11: DELETE button

With delete button we just need to point the mouse then press the delete button the program will give aform to confirm that you want to delete that record then the program will delete all the data of thatrecord even in ArrayList Book and file BookList.txt

Figure 12: SEARCH

With the search section, we just need to enter the ID of the book in the search bar and the program will search in the table and then display it on the table automatically without having to press a button

How I handle errors:

- Error when the user has not selected the object to update or delete

Figure 13: UnSelected row

- Error when the user update or add same ID

Figure 14: Duplicate ID

- Error when the user do not fill completely information

Figure 15: ADD error handle

- Error when we get information from unadded column in ArrayList named Book

6 Running program:

Figure 17: Running program

This is the main interface of the program Although the design is not too splendid, the information displayed is extremely detailedand clear The program is divided into three parts: The first part includes the search function and the body contains the list ofstudents and the input form The top part is the logo with the search bar right below it is a blank box used to enter information,command buttons, table

Figure 18: Logo and Search bar

For the upper part I arrange the objects in this section horizontally to save space and besides, it helps users to operate easily fromleft to right in order of function and selection The search bar will be located at the top like other applications and programs so thatusers feel familiar

Figure 19: Table and Upload button

Figure 20: Get information form

This is a form for entering book information when the user adds or updates book information The fields in the form are spacedapart to keep the form clear, so users don't have to feel uncomfortable filling out the form

Figure 21: Buttons

It is the soul of the program and helps the program work according to the user's requirements The keys are fairly evenly spaced so users don't have to worry about pressing the wrong one We have added icons to make the buttons more vivid so that the users don't get bored

7 Conclusion:

specifically I learned and worked with JFrame which is completely new than before

Strong point:

My program over time learning, I improve the program more complete with outstanding features such as:

Search, Update and Delete
