Core - JAVA Lab Manual
- Develop a Java application to generate Electricity bill.
Create a class with the following members: Consumer no.,
consumer name, previous month reading, current month
reading, type of EB connection (i.e domestic or
commercial). Compute the bill amount using the following
tariff.
If the type of the EB connection is domestic, calculate the
amount to be paid as follows:
First 100 units - Rs. 1 per unit
101-200 units - Rs. 2.50 per unit
201 -500 units - Rs. 4 per unit
> 501 units - Rs. 6 per unit
If the type of the EB connection is commercial,
calculate the amount to be paid as follows:
First 100 units - Rs. 2 per unit
101-200 units - Rs. 4.50 per unit
201 -500 units - Rs. 6 per unit
> 501 units - Rs. 7 per unit
- Develop a java application to implement currency converter
(Dollar to INR, EURO to INR, Yen to INR and vice versa),
distance converter (meter to KM, miles to KM and vice versa),
time converter (hours to minutes, seconds and vice versa) using
packages.
- Develop a java application with Employee class with
Emp_name, Emp_id, Address, Mail_id, Mobile_no as
members. Inherit the classes, Programmer, Assistant
Professor, Associate Professor and Professor from employee
class. Add Basic Pay (BP) as the member of all the inherited
classes with 97% of BP as DA, 10 % of BP as HRA, 12% of
BP as PF, 0.1% of BP for staff club fund. Generate pay slips
for the employees with their gross and net salary.
- Design a Java interface for ADT Stack. Implement this
interface using array. Provide necessary exception handling
in both the implementations.
- Write a program to perform string operations using Array List.
Write functions for the
following
a. Append - add at end
b. Insert
add at particular
index
c. Search
d. List all string starts with given letter.
- Write a Java Program to create an abstract class named Shape
that contains two integers and an empty method named print
Area(). Provide three classes named Rectangle, Triangle
and Circle such that each one of the classes extends the class
Shape. Each one of the classes contains only the method print
Area () that prints the area of the given shape.
- Write a Java program to implement user defined exception
handling.
- Write a Java program that reads a file name from the user,
displays information about whether the file exists, whether the
file is readable, or writable, the type of file and the length of
the file in bytes.

- Write a java program that implements a multi-threaded application that has three threads. First thread generates a random integer every 1 second and if the value is even, second thread computes the square of the number and prints. If the value is odd, the third thread will print the value of cube of the number.
- Write a java program to find the maximum value from the given type of elements using a generic function.
- Design a calculator using event-driven programming paradigm of Java with the following options.
a) Decimal manipulations
b) Scientific manipulations
