Description
Description:
The following workshop lets you practice basic java coding techniques, creating classes, methods,
using arrays, Java I/O, inheritance, polymorphism, Exceptional Handling, JavaFx (GUI). The focus
will be practicing for JavaFx concepts.
Task 1: Write a program to display a simple Address Book screen as show below
Task 2 (Event-Handling): The following task is a continuity of Task – 1 and based on some
research as well.
Research Part:
During the lecture of Week 5 and in the workshop 4 you have practiced different concepts on
• How to read a file.
• How to write a file.
• Mostly everyone has practiced FileReader or FileWriter, FileInputStream or
FileOutputStream, Buffered Readers etc.
• Task – 2 required you to first search on RandomAccessFile in Java, o Advantages.
JAC – 444 Semester ——–
o Where to use it.
o How to use it.
Once you have read about the advantages and disadvantages of the RandomAccessFile in java
then you can start the coding for the workshop.
Coding Part:
Write a program that stores, retrieves, adds and updates addresses as shown in the
figure below.
• Use random access file for reading and writing an address.
• When the program starts your files should contains minimum 5 proper records
[make sure the added records are proper not some random strings and/ or postal
code etc].
Hint: Use fixed-length string for storing each attribute in the address.
Deliverables for Task – 2: there will be two different deliverables for this workshop.
1. A word document includes your findings about Random Access File.
a. Advantages
b. Disadvantages
c. Usage.
d. Syntax.
e. Constructors
f. Methods
Note: Also include your references from where you search.
2. Code for the application.
