Bubble Sort in Java

Here is a simple program to sort numbers in ascending as well as descending order using bubble sort

import java.io.*;

public class Bubble {

static int arr[] = new int[5];
static String str[] = new String[5];

static void display()
{
for(int i=0;i<arr.length;i++)
{
System.out.print(" "+arr[i]);
}
}

public static void main(String[] args) throws IOException {
// TODO Auto-generated method stub

System.out.println("Enter 5 numbers to sort : ");
for(int i=0,j=1;i<arr.length;i++)
{
System.out.print(j+") ");
str[i] = new BufferedReader(new InputStreamReader(System.in)).readLine();
j++;
}
for(int i=0;i<str.length;i++)
{
String str1 = str[i];
int val = Integer.parseInt(str1);
arr[i] = val;
}
display();

System.out.print("
Select Sorting Order (ascending(a)/descending(d) : ");
String str2 = new BufferedReader(new InputStreamReader(System.in)).readLine();
if(str2.equalsIgnoreCase("a"))
{
for(int i=0;i<=arr.length-1;i++)
{
for(int j=0;j<=arr.length-1;j++)
{
if(arr[i] < arr[j])
{
int tmp = arr[i];
arr[i] = arr[j];
arr[j] = tmp;
}
}
}
display();
}
if(str2.equalsIgnoreCase("d"))
{
for(int i=0;i<=arr.length-1;i++)

Getting Started with Java

A Java program is a collection of one or more java classes. A Java source file can contain more than one class definition and has a .java extension. Each class definition in a source file is compiled into a separate class file. The name of this compiled file is comprised of the name of the class with .class as an extension. Before we proceed further in this section, I would recommend you to go through the ‘Basic Language Elements’.

Below is a java sample code for the traditional Hello World program. Basically, the idea behind this Hello World program is to learn how to create a program, compile and run it. To create your java source code you can use any editor( Text pad/Edit plus are my favorites) or you can use an IDE like Eclipse.

public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World");
}//End of main
}//End of HelloWorld Class

Output
Hello World




Compiling and Running an Application

To compile and run the program you need the JDK distributed by Sun Microsystems. The JDK contains documentation, examples, installation instructions, class libraries and packages, and tools. Download an editor like Textpad/EditPlus to type your code. You must save your source code with a .java extension. The name of the file must be the name of the public class contained in the file.

Steps for Saving, compiling and Running a Java

Step 1:Save the program With .java Extension.
Step 2:Compile the file from DOS prompt by typing javac .
Step 3:Successful Compilation, results in creation of .class containing byte code
Step 4:Execute the file by typing java



PATH and CLASSPATH

The following are the general programming errors, which I think every beginning java programmer would come across. Here is a solution on how to solve the problems when running on a Microsoft Windows Machine.

1. ‘javac’ is not recognized as an internal or external command, operable program or batch file

When you get this error, you should conclude that your operating system cannot find the compiler (javac). To solve this error you need to set the PATH variable.

How to set the PATH Variable?

Firstly the PATH variable is set so that we can compile and execute programs from any directory without having to type the full path of the command. To set the PATH of jdk on your system (Windows XP), add the full path of the jdk\bin directory to the PATH variable. Set the PATH as follows on a Windows machine:

a. Click Start > Right Click “My Computer” and click on “Properties”
b. Click Advanced > Environment Variables.
c. Add the location of bin folder of JDK installation for PATH in User Variables and System Variables. A typical value for PATH is:

C:\jdk\bin (jdk
If there are already some entries in the PATH variable then you must add a semicolon and then add the above value (Version being replaced with the version of JDK). The new path takes effect in each new command prompt window you open after setting the PATH variable.

2. Exception in thread “main” java.lang.NoClassDefFoundError: HelloWorld

If you receive this error, java cannot find your compiled byte code file, HelloWorld.class.If both your class files and source code are in the same working directory and if you try running your program from the current working directory than, your program must get executed without any problems as, java tries to find your .class file is your current directory. If your class files are present in some other directory other than that of the java files we must set the CLASSPATH pointing to the directory that contain your compiled class files.CLASSPATH can be set as follows on a Windows machine:

a. Click Start > Right Click “My Computer” and click on “Properties”
b. Click Advanced > Environment Variables.

Add the location of classes’ folder containing all your java classes in User Variables.

If there are already some entries in the CLASSPATH variable then you must add a semicolon and then add the new value . The new class path takes effect in each new command prompt window you open after setting the CLASSPATH variable.

ONLINE UNIVERSITY DATABASE CREATION

To create a new Database, open the MS Access and select ‘Blank Access Database’ and click at OK. This is shown below:
User Maintenance Manual

This project titled ‘On-Line University’ has been built using JSP, which is a server side program. So to run this program on a personal computer, a web server such as Java Web Server2.0 or Apache Tomcat 4.0’, is needed. Here ‘Tomcat’ is used.

In this CD, there is a folder named ‘University’ and inside this folder there are another three folder named ‘htmls’, ‘jsps’ and ‘database’. The ‘htmls’ contains html codes, the ‘jsps’ contains jsp codes and ‘database’ contains databases created on MS Access.

Procedures for Apache Tomcat 4.0 web server

The folder ‘University’ should be included inside the ‘Tomcat’ as follows:

Note:

Copy University Folder and paste it under

C:\Program Files\Apache Tomcat 4.0\webapps\examples\jsp







Then another window will be opened as shown below. In this window we can select the Drive where we want to save this database file.




After selecting the Drive, assign a name to the Database file, which we are going to create and click at the button. Then another window will be opened as shown below:





In the above figure, we can see that three ways to create a database. Among this, select the second one (as shown in the picture) and double click on it. Then another window will be selected as shown below:




Here we can select the subject for the ‘Sample Tables’ by choosing ‘Business or Personal’. Here I chose ‘Book’ as the subject for the Sample Tables. If we choose a


Subject for the Sample Tables, its possible attributes will be appeared on the ‘Sample Fields’. From this field we can choose the fields that we would like to have. Here I selected ‘BookID, Title and Copyright Year’. This can be done by clicking the button while keeping a sample field is selected. After this, click next and another window will be opened as shown below:

ONLINE UNIVERSITY - SYSTEM ANALYSIS
Operations in the Existing System


Registration

The students those who are looking for pursuing a course at any college under the ABCD University has to pass the qualifying examination or any other examination, recognized by this University as equivalent to it, with a minimum of 55% marks. Relaxation of marks will be allowed to SC/ST students. Even if the student has passed the qualifying course he/she must also have attained the minimum age prescribed for admission to the course.


Apart from this at the time of admission the students are required to present their transfer certificate (T.C) and a conduct certificate from the institution they have last studied. If student is an over aged private S.S.L.C holder then that student is exempted from producing the Transfer Certificate at the time of admission in the affiliated colleges and also for Private Registrations. If the student had studied in an institution outside the territorial jurisdiction of this University and presently he/she wish to seek admission to a College/Institution or any of the University’s Departments of Study and Research in this University, in addition to the above said requirements they should also produce a Migration Certificate.

The students shall also produce an Eligibility Certificate that can be had from the Registrar by submitting an application form with a prescribed fee. Candidates who migrate from other Universities should register as matriculates of this University at the time of admission by paying the prescribed fee. If one fails to produce the Migration Certificate as requested by the University, then he/she will not be allowed to take any examination of this University. Admission to colleges or other institutions under the University will not be permitted after two months from the date of reopening of the college or University Department concerned, except with the previous permission of this University. However, he/she may be permitted to join the certain part-time courses conducted by the University or by a college affiliated to this University or by a Center for study and research of this University. No Candidate who has passed an examination from this University or from any other University shall be permitted to take an examination of this University or to join the course leading to that Examination or part or parts thereof which is considered lower than the one he has passed


Draw backs of the Existing System
The main problem with the existing system is that it takes so long for completing the registration process. Also there may cause the problem of losing application or registration forms while sending the forms to and fro. Besides all that, all the databases of these students have to be entered in to the computer by the data entry operator and it is a tedious as well as a time consuming process. Here also errors-like unfilled columns in the forms, losing data, etc may occur while creating the databases for the students. If anyone’s form is not filled completely, his or her registration or application form will not be taken into consideration.
In the case of admission, students are not aware of the number of seats available in each college for a certain course. Difficulty arises when the student came to know that the college to which he/she applied for a certain course does not have sufficient number of seats. In such cases, again, the student has to submit another admission form, for which he/she has to follow all the rules and formalities that the student had done when applied for the first time. As far as a student is concerned, it is all time consuming processes and they have to wait till for a replay from the University/College authorities.
While applying for an exam, students have to submit all the examination forms and the exam fee receipt before the date. This is very difficult for the students those who are coming from very long distance and from outside state.


Proposed System and its Advantages
If the University has On-Line services, the above-mentioned problems will be solved to some extend. Students can register for a course through on-line thereby they can avoid the missing of forms, waiting so long for the replay, etc. Through on-line, students can fill up the registration form and it can be send within a fraction of a second. While doing on-line registration, students cannot leave any columns as blank, as the system reminds them of that. So the students can avoid such mistakes that might be leading to the cancellation of their registration. As soon as the students registered for the course, they will get the further information from the University at once.
With the help of On-Line registration, the students need not wait for days or weeks for the result. While doing On-Line registration, the students will be informed of their college, their course, their admission number, their registration number etc. Also when students are registering through On-Line, they have to fill up their academic details, personal details, mark lists, etc in the registration form. So the details in the forms are directly going to the server of the University so that the university needn’t have to create a separate database for the student.
The proposed system offers on - line facilities like viewing the Course details, College details, Exam results, Registration for both Admission and Examinations etc. In the administration side, the administrator can enter new details such as adding new colleges, allotting seats, entering new course details, entering exam results etc.
