Micro-Project Report
1.0 Rationale:
Abstraction in JAVA shows only the essential attributes and hides unnecessary details
of the object from the user. In Java, abstraction is accomplished using Abstract class,
Abstract methods, and Interfaces. Abstraction helps in reducing programming
complexity and effort.
ABSTRACT CLASS is a type of class in Java, that declare one or more abstract
methods. These classes can have abstract methods as well as concrete methods. A normal
P
class cannot have abstract methods. An abstract class is a class that contains at least one
AP
abstract method.

Java Programming - 22412 Calculate Area Of Any Type Of Shape Using Abstract Class.
4.0 Literature Review:
i. An abstract class may also have concrete (complete) methods.
ii. For design purpose, a class can be declared abstract even if it does not contain any abstract
methods:
iii. Reference of an abstract class can point to objects of its sub-classes thereby achieving run-
time polymorphism Ex: Shape obj = new Rectangle();
iv. A class must be compulsorily labelled abstract, if it has one or more abstract methods.
Advantages of Abstraction:
i. Abstract class in Java is highly beneficial in writing shorter codes.
ii. Abstraction in Java avoids code duplication.
iii. Abstract classes enable code reusability.
P
iv. Changes to internal code implementation are done without affecting classes.
Rules For Abstract Class in Java are as follows:

9.0 Skills Developed:
During the course of this micro-project, we learnt to create a program on area of
shapes using abstract class.
a) We learnt various syntaxes of Java language.
b) We learnt to create area of shape through abstract class.
c) We also learnt abstraction of a Class.
10.0 Applications of this Micro-project:
P
This micro-project finds its application in:
AP
Abstraction in JAVA shows only the essential attributes and hides unnecessary details
of the object from the user. In Java, abstraction is accomplished using Abstract class,
Abstract methods, and Interfaces. Abstraction helps in reducing programming

11.0 Area of future Improvement:
So
For future, in a project specially for larger projects and many class files in a abstract
class can be created for different uses like in a main file for importing arithmetic
E
operations, classes can be created named arithmetic_operations in which different
T
class file for different operations like addition, subtraction, multiplication etc. can be
SB
created and for string operations package named string_operation can be developed for
operations like reversing, finding length, concatenating etc. can be made.
M
12.0 Conclusion:
We learn to calculate area of various shape. Also, we developed a java file and learnt
various syntax in java.
