Assignment No. – 1.A

Aim: - Write a program to create student database to implement Object Oriented features such

as: Class, Object, Method, String, Vector, Exception Handling etc.

Steps:

1. Define a class that declares data types to store student information. (Data types like

strings are used to store student name, address, branch, subject names etc.)

2. Define another class which will inherit the first class as well defines methods to

perform operations on student information. It defines menu to perform different

operations on Student record such as: ADD Record, Display, Search, Update,

Delete etc.

3. Second class creates a vector that stores instance (objects) of first class with new

student record. Vector Provide different inbuilt functions like elementAt,

addElement, removeAll etc. using them we can perform any operation on Vector.

4. Second class also defines Main method. In this class make object of the classes and

access the variables defined in classes. Then performs specified operation using that

objects.

Aim: - Write a program to implement Multilevel Inheritance with access specifiers for

calculation of Employee salary on daily basis for both teaching and non-teaching

staff. Use following Structure

Steps:

1 Define all classes as per shown in above fig. that declares data types to store

Employee Information. (Data types like strings are used to store Emp name,

address, branch, ID etc.)

2 Figure shows multiple levels of inheritance. Each class inherits properties of

Parent class including own properties. (using interface we can implement multiple

inheritance).

3 First class defines menu to perform different operations on Employee record such

as: ADD Record, Display, Search, Update, Delete etc. While displaying

information it computes salary of employee from basic salary.

4 First class also defines Main method. In this class make objects of different

classes and access the variables defined in classes. Then performs specified

operation using that objects using different methods defined in classes.

Assignment No. – 3

Aim: - Write a program to display an animated clock that shows day, date and time using multithreading.

Steps:

1. Creating threads :

In the most general sense, you create a thread by instantiating an object of type

Thread. Java defines two ways in which this can be accomplished:

You can implement the Runnable interface.

You can extend the Thread class, itself.

2. Implementing Runnable:

The easiest way to create a thread is to create a class that implements the Runnable

interface. Runnable abstracts a unit of executable code. You can construct a thread

on any object that implements Runnable To implement Runnable a class need only

implement a single method called run(), which is declared like this:

Public void run()

3. Extending Thread:

The second way to create a thread is to create a new class that extends Thread and

then to create an instance of that class. The extending class must override the run()

method, which is the entry point for the new thread. It must also call start() to begin

execution of the new thread.

4. Creating Clock:

To create animated clock use Applet and using different properties of Applet we can

create clock.

5. Display Clock:

By accessing system clock we can display animated clock with rotating hands.

Aim: - Write a program to retrieve data from some database table using JDBC.

Steps: 1. Loading the driver

Import java.sql packageTo load the driver class.for Name ( ) method is used

Class . for Name ( “ sun . jdbc.odbc.jdbcodbc driver”) ;

When the driver is loaded , it register itself with the java.sql.drivermanager class

as an available database driver

2. Making a connection with database

To open a connection to a given database

driver manager.get Connection ( ) method is used

Connection con = drivermanager.getconnection

( “ jdbc:odbc:somedb”,”user”,”password”);

3. Executing sql statements

To execute a sql query , java sql.statement class is used

Statement stmt = con.createstatement ( )

A query that returns data can be executed using the executequery ( )

Method of statement this method execute the statement and returns java.sql.resultset that

encapsulates the retrieved data

Resultset rs = stmt.executequery (“ SELECT * from some table”);

4. Process the result

Resultset returns one row at a time Next( ) method of the resultset.object can be called to

move the next row the getstring ( ) and get object ( ) methods are used for retrieving

column values

while ( rs.next ( ) )

{string event = rs.getstring ( “event”);

Object.count = (Integer)rs.getobject(“count”);

Assignment No. – 3.A

Aim: - Write a program to demonstrate DOS memory management mechanism.

Program to implement job scheduling algorithms

1. FCFS

2. SJF

3. Priority

4. Round Robin

Steps:

Theory:

• What is job scheduling and necessity of job scheduling?

• Stack simulation for First come First Serve(FCFS),

• Shortest Job First(SJF) :preemptive and non-preemptive

• Round Robin(RR)

Take the input as arrival time, processes, priority and completion time.

For FCFS the processor is handed over to the process which has

arrived first so keep track of arrival of process.

For RR the processor is handed over to the process for equal

amount of time quantum which is specified by user & if time over

then handed to next process.

For SJF the arrival time for all the processes is compared and the

process with less arrival time has handed over the CPU.

In Preemptive Scheduling the process with less execution time

than the currently allocated process will preempt the current

process but in non preemptive case it does not happen.

Aim: - Program to implement Dynamic Link Library using VC++

Steps:

Method 1: Easy VC++, Hard VB1. VC++: Invoke New\Projects\Win32 Dynamic-Link Library. Enter the

directory where you want the VC++ project and the project name (MyFuncsProject in the example).

2. VC++: Invoke New\Files\C++ Source File. Check the Add To Project box. Enter the file name (MyFuncs.cpp in the example).

3. VC++: Enter the function's source code. Use __declspec (note the two

underscores) to export the function's symbol. Use 'extern "C"' to minimize

name mangling by VC++.

// Define DllExport to declare exported symbols.#define DllExport __declspec( dllexport )

// Prototype the function.// Use 'extern "C"' to minimize name mangling.extern "C" DllExport long MyCFunc(long x);

// Define the function.extern "C" DllExport long MyCFunc(long x){ return x * x;

}

4. VC++: Set project options using Project\Settings. On the C/C++ tab, select the Code Generation category. Then change Calling Convention to __stdcall.

5. VC++: Select Build\Set Active Configuration. Select the Release configuration. Repeat step 4 to make the options apply to the release configuration in addition to the debug configuration. Use Build\Set Active Configuration to reselect the debug configuration if desired.

6. VC++: Build the project (press F7 or use the Build menu). This creates the DLL file.

VB: In your Visual Basic program, declare the DLL function using the DLL file's full

path name. The function's name in the DLL file has been slightly mangled by VC++.

The name is an underscore, followed by the name you gave it, followed by "@",

followed by the number of bytes in the function's argument list. In this example the

21

Software Laboratory

name is _MyCFunc@4 because the function takes one 4 byte argument (a long

integer).

Private Declare Function MyCFunc Lib _ "C:\VBHelper\VcDll\Method1\Release\MyFuncsProject.dll" _ Alias "_MyCFunc@4" _ (ByVal x As Long) As Long

Private Sub Command1_Click()Dim x As LongDim y As Long

x = CInt(Text1.Text) y = MyCFunc(x) Label1.Caption = Str$(y)

End Sub

*** HINT: To quickly determine the mangled name of the function, find the DLL file in Windows Explorer. Right click on the file and select the "Quick View" command. This presents an editor showing information about the DLL. Page down 2 or 3 pages and you will find a list of exported symbols available in the DLL. One of these will be the mangled function name.

VB: Run the program.
