ITY 392 – PROGRAMMING LAB -3
Lab Objective
1) Introduction to object oriented programming concepts- java as an object oriented programming
language. Introduction to java application and applets-control structures-methods-arrays.
2) Object based and object oriented programming creating packages-using overloaded constructorsstatic class variables-data abstraction and information hiding-relation between super class objects and
subclass objects composition verses inheritance-polymorphism- dynamic method binding abstract
super classes and concrete super classes –inheriting interface-use of inner classes and wrapper classes
3) Exception handling and multithreading in object oriented programming- When exception
handling should be used-java exception handling – exceptions and inheritance-multithreading
in java-thread synchronization-daemon threads Runnable interface
Writing of the experiment:
The student has to write the experiment as per the following format:
a) Name of the experiment/Aim
b) Algorithm
c) Source Program
d) Input and Output
e) Result

SAMPLE EXERCISE
AIM:
Write a java program to find the simple interest.
Algorithm:
Step by step procedure followed to find the simple interest
Source Program
public class SimpleInterestTest{
public static void main(String args[]) {
//creating scanner to accept principle, rate and time input form user
Scanner scanner = new Scanner(System.in);
System.out.println("Welcome in Java program to calculate Simple interest");
System.err.println("Please enter principle amount :");
float amount = scanner.nextFloat();
System.err.println("Enter time in years : ");
float time = scanner.nextFloat();
System.out.println("Enter rate annually : ");
float rate = scanner.nextFloat();
float interest = simpleInterest(amount, rate, time);
System.out.println("Simple interested calculate by program is : " + interest);
}
public static float simpleInterest(float principle, float rate, float time){
float interest = (principle*rate*time)/100;
return interest;
}
}
Output:
Welcome in Java program to calculate Simple interest
Please enter principle amount :
1000
Enter time in years :
1
Enter rate annually :
7
Simple interested calculate by program is : 70.0
Test Data:
a) Valid data sets: 25000 int value as principal, 12.5f float value as rate, 2.75 as
double as interestToPay
b) Limiting value sets: Only integer values can be stored in the var. principal.
c) Invalid data sets: If we assign float value in var. principal error will occur.
Results for different data sets:
Principalamount is Rs.25000 interest=Rs.8593.75
Total amount to pay to clear the loan = Rs.33593.75
