A Micro-Project REPORT On
“Temperature Converter”
1. Rational:-
Java technology is widely used for web applications
development. Based on the object oriented concepts and core
Java concepts, this course will equip the students with the
required knowledge and skill of object oriented
programming approach needed for the development of
robust, powerful web applications. Through this course
students will get hands-on experience on GUI Technologies
viz. AWT and Swings, event handling mechanisms and
network programming. The course also gives coverage to
various web applications aspects like Database Interaction,
server side components and servlets.
2. Aim/Benefit of the Micro-Project:-
The aim of a temperature converter is to facilitate the
conversion of temperature values between different scales,
such as Celsius, Fahrenheit, and Kelvin. This tool helps
users accurately translate temperature readings for various
applications, including scientific research, cooking, and
travel, ensuring clarity and consistency in temperature
measurement.
3. Course Outcomes Addressed:-
a. Develop program using GUI framework.
b. Handle events of AWT and Swing Components.
c. Develop program to handle events in Java Programming.
4. Actual Methodology Followed:
1. First we decided the topic of micro-project that
“Temperature Converter”.
2. Then we planned the whole process of completing the
micro-project and also the design of the micro-project with
team member’s accordingly.
3. Then we prepared the proposal of the micro-project
accordingly.
4. Then we finalized the how to make proposal among us.
5. We later started gathering and collecting the information
about our project.
6. Then we write program on our project.
7. After collecting our required information we started
preparing report of the project and submitting soft-copy to
teacher.
5. Code of micro-project:
