Library Management System Java Project
Library Management System Project Abstract:
LMS is a software application useful for librarians in any educational institution for management and handling of typical operations in the library. It manages data through computerized system in a database which eradicates the tediousness in searching a particular book in the entire library.
Existing System:
The existing library management system is very traditional and manual. Most of the things such as record of students who’ve issued the book, no. of books in the library, fine of students, etc. are recorded using pen-paper system. This traditional system requires a lot of time and manpower for performing simple operations in the library.
The drawbacks of existing system are:
- Record keeping is paper-based.
- The system is not computerized.
- There’s high risk of data mis-management.
- Students face a lot of problem while searching a book.
- Chances of book theft from the library is high.
- A lot of paperwork and manpower is to be allocated for simple library management operations.
- The existing system is very inefficient and unreliable.
Proposed System:
The proposed library management software is developed after the analysis of issues, problems, and drawbacks of the existing system. Here, different modules have been assigned for managing and organizing different tasks in a library. Using this software, librarian can store information of all the books, with author name, faculty, etc., available in the library. Only one person can handle the entire library.
The main feature of this system is that all the books available in the library can be displayed in a list so that students need not roam through the entire library to find a book. Additionally, the application effectively maintains the details of users/students to whom books have been issued; it also records the issued date and return date.
Features:
- Add, modify and delete book details into the database.
- Search feature for finding book availability in library stock.
- Add students records upon issue of a book.
- Record issue date, return date, and fine (penalty).
- Payment system/feature allows the librarian to calculate payment details and print bill.
Technologies and Products Used:
- NetBeans 5.0
- Tomcat 5.5 embedded in NetBeans
- Oracle10g Express Edition
- Jboss 4.0.3
- Java Server Pages (JSP)
- Java Beans
- Enterprise Java Beans
Modules Overview:
- Insertion Module: With the help of this module, librarian can insert information and details of users along with book details and time and date of book issue.
- Updating Module: This module allows modification to the existing records and details in the library management system database.
- Report Generation Module: This module allows task such as printing payment details, stock details of books, etc.

R19 JAVA PROGRAMMING LAB
Exercise - 1 (Basics)
a) Write a JAVA program to display default value of all primitive data type of JAVA
Program:
class DefaultValues
{
byte b;
short s;
int i;
long l;
float f;
double d;
char c;
boolean bl;
String s;
public static void main(String[] args)
{
DefaultValues df=new DefaultValues();
System.out.println("Byte :"+df.b);
System.out.println("Short :"+df.s);
System.out.println("Int :"+df.i);
System.out.println("Long :"+df.l);
System.out.println("Float :"+df.f);
System.out.println("Double :"+df.d);
System.out.println("Char :"+df.c);
System.out.println("Boolean :"+df.bl);
System.out.println("String :"+df.s);
}
}
Output:
b) Write a java program that display the roots of a quadratic equation ax2+bx+c=0. Calculate the discriminate D and basing on value of D, describe the nature of root.
NOTE:
The java.lang.Math class contains methods for performing basic numeric operations such as the elementary exponential, logarithm, square root, and trigonometric functions.
Program:
//Java Program to Find Roots of a Quadratic Equation
import java.util.Scanner;
class Quadratic
{
public static void main(String[] args)
{
//double a = 2.3, b = 4, c = 5.6;
double a,b,c;
System.out.println("Enter a,b,c values:");
Scanner scan=new Scanner(System.in);
a=scan.nextFloat();
b=scan.nextFloat();
c=scan.nextFloat();
double root1, root2;
double determinant = b * b - 4 * a * c;
// condition for real and different roots
if(determinant > 0)
{
root1 = (-b + Math.sqrt(determinant)) / (2 * a);
root2 = (-b - Math.sqrt(determinant)) / (2 * a);
System.out.format("root1 = %.2f and root2 = %.2f", root1 , root2);
System.out.println("\nRoots are real and different");
}
// Condition for real and equal roots
else if(determinant == 0)
{
root1 = root2 = -b / (2 * a);
System.out.format("root1 = root2 = %.2f;", root1);
System.out.println("\nRoots are real and equal");
}
// If roots are not real
else
{
double realPart = -b / (2 *a);
double imaginaryPart = Math.sqrt(-determinant) / (2 * a);
System.out.format("root1 = %.2f+%.2fi and root2 = %.2f-%.2fi",realPart, imaginaryPart, realPart, imaginaryPart);
System.out.println("\nRoots are imaginary"); //complex and different
}
}
}
Output:
c) Five Bikers Compete in a race such that they drive at a constant speed which may or may not be the same as the other. To qualify the race, the speed of a racer must be more than the average speed of all 5 racers. Take as input the speed of each racer and print back the speed of qualifying racers.
Program:
import java.util.*;
class Race
{
public static void main(String a[])
{
int r1,r2,r3,r4,r5,avg;
Scanner s=new Scanner(System.in);
System.out.println("enter the speed of the r1 r2 r3 r4 and r5");
r1=s.nextInt();
r2=s.nextInt();
r3=s.nextInt();
r4=s.nextInt();
r5=s.nextInt();
avg=(r1+r2+r3+r4+r5)/5;
if(r1>avg)
{
System.out.println("first racer is qualified with a race speed "+r1+"\n");
}
else if(r2>avg)
{
System.out.println("second racer is qalified with a race speed "+r2);
}
else if(r3>avg)
{
System.out.println("third racer is qalified with a race speed "+r3);
}
else if(r4>avg)
{
System.out.println("fourth racer is qalified with a race speed "+r4);
}
else if(r5>avg)
{
System.out.println("fifth racer is qalified with a race speed "+r5);
}
else
{
System.out.println("no biker is qualified");
}
}
}
