What is difference between a class and an object with respect to Java?


This kind of question is a test of your knowledge of the terminology associated with object oriented programming. You should note that this question could just as well be asked in the context of a C++ programmer interview, or any programming position that requires object oriented programming for that matter.
The terms 'class' and 'object' are definitely related to one another, but each term holds its own distinct meaning. Let's start out by explaining what the term "class" means in the context of OOP. The term 'class' refers to the actual written piece of code which is used to define the behavior of any given class. So, a class is a static piece of code that consists of attributes which don't change during the execution of a program - like the method definitions within a class.
An object is an instance of a class The term 'object', however, refers to an actual instance of a class. Every object must belong to a class. Objects are created and eventually destroyed - so they only live in the program for a limited time. While objects are 'living' their properties may also be changed signficantly.
An example will help clarify what we've said. Suppose we have a class called 'Animal'. All Animals have bodies and brains - and these could be the attributes of our fictional Animal class. We can also add some methods that would be common to all Animals - like "movement", because all animals can move (maybe you can think of a better example for methods, but hopefully you get the point). So, the idea you really want to enforce in your own mind is that this very general 'template' of an Animal does not change - it's simply just some lines of code that define the Animal class.
An instance of the Animal class would be a specific animal - like a lion, a cat, or a zebra. These instances of the Animal class would be called objects. Whereas the Animal class is a general concept, the instances of that class - the lions, cats, etc - take that general concept and create a real instance of it. That is why programmers define constructors for their classes - so that when someone wants to create an object of the class, he/she can just pass in the actual properties that he/she wants the object to have - like what kind of animal it is, the name, the weight, etc. So, you can think of a constructor as something that brings the class to life - which is why it is called a constructor, because it constructs a specific instance of a class.
Objects have a lifespan but classes do not And, as our Animal example clearly shows, every object has a lifespan associated with it - a cat or zebra can not live forever. And, the properties of those objects can change as well while they 'live'; if we have a 'size' variable defined in the class that would of course change as the cat object grows bigger.
Object versus class summary So, we can say that whereas a class is a general concept (like an Animal), an object is a very specific embodiment of that class, with a limited lifespan (like a lion, cat, or a zebra). Another way of thinking about the difference between a class and an object is that a class provides a template for something more specific that the programmer has to define, which he/she will do when creating an object of that class.

Can you give an example of compiler using vb?


Dim parameters As New CompilerParameters() Dim results As CompilerResults parameters.GenerateExecutable = True parameters.OutputAssembly = Output results = icc.CompileAssemblyFromSource(parameters, SourceText)
The code above uses the CompilerParameters object to tell the compiler that you want to generate an executable file (as opposed to a DLL) and that you want to output the resulting assembly to disk. The call to CompileAssemblyFromSource is where your assembly gets compiled. This method takes your parameters object and the source code, which is a string. Once you compile your code you can check to see if there were any compilation errors. We use the return value from CompileAssemblyFromSource, which is a CompilerResults object. This object contains an errors collection, which contains any errors that occurred during the compile.
There are other options for compiling, such as compiling from a file. You can also batch compile, which means you can compile multiple files or sources at the same time. Additional information on these classes is available on MSDN Online:

Example sorurce code for database


Hello my friend try this code: This code is design for Visual Basic 6.0
Function for Connection and recordset string.  '========Connection String====== Public Sub connection(ByRef dConnection As ADODB.connection, ByVal dLocation As String)     dConnection.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & dLocation & ";Persist Security Info=False;" End Sub '======End of Connection String======
'=======Recordset String=========== Public Sub recordset(ByRef sRecordset As ADODB.recordset, ByRef sConnection As ADODB.connection, ByVal sSQl As String) With sRecordset .CursorLocation = adUseClient .Open sSQl, sConnection, adOpenKeyset, adLockOptimistic End With End Sub '======End Recordset String========
How to apply the above function? Application:
'====== Command Save Button======== Private Sub cmdsave_Click() Dim cn3 As New ADODB.connection Dim rs3 As New ADODB.recordset
Call connection(cn3, App.Path & "\CASGC.mdb") Call recordset(rs3, cn3, "Select * from Debtor_Creditor_Account") Set dtglobal.DataSource = rs3.DataSource   
With rs3   .AddNew   .Fields("Code") = txtCode.Text   .Fields("Description") = txtDescription.Text   .Fields("Tag") = cbotag.Text   .Update   .Requery    End With   MsgBox "New Account has been Added", vbInformation   Set cn3 = Nothing Set rs3 = Nothing
End Sub '=======end of Command Save button=====
The advantage of using this code is setting your database connection is you have a reliable connection towards your database where ever you place your database you can you don't to remount you databse connection control. Also you are no longer need to use a ADO control or DAO control just copy the function and paste it in your coding area and call the function and you have now a working database and recordset connection string.

Can i get vba code to list objects in a group in listbox1 without ungrouping the object?


You can look at each item in the Groupitems collection of a group. Those are the shapes if they are grouped.:

Sub group()
For Each one In ActiveSheet.Shapes
If one.GroupItems.Count > 0 Then
For Each one2 In one.GroupItems
MsgBox (one2.Name)
Next
End If
Next
End Sub

Write into excel format


You can use ADO or SQL to open the excel file directly (provided it is constructed correctly, ie fields names) and write the data to it without Access.
That might be eaiser thatn converting it from Access to Excel, if that can even be done.

Access of image file through c/c++ programme.


The best way to do this is to use Visual C++ or .NET's C# and use an image object to hold the binary image data as you address/manipulate it. If you are doing this as a web-based application, then ASP.NET using C# is the way to go, again using an image object. 
There are many helpful developer site for the beginner through expert that can walk you through the use of an image object. There are also many variants of the image object and you'll have to decide which one best suits your needs. Start with the generic one to get your base code loading and addressing the image and go from there.
Here's a good starting point.
Hope this helps.

Java gui code


Okay. I'll try and explain what this code is doing for you.

First thing you need to understand is your "gui" is what is known as "Standard Out" and "Standard In", this is how Java outputs text to the console, and how it inputs text written by a user from the console. A function like "System.out.println([some string])" will print out that line to the console.

Second thing is the idea of classes. A class can be thought of like a code "blueprint". You write the blueprint, and then you create individual "objects" based on that class in your code. While each object is independant, and has it's own properties, functions, and its own spot in memory, it is based on the same code.

If I made a class called, say, "Shape", and I gave it two properties, "Size" and "Color", then I could in my program make lots of different "Shape" objects and they would each have their own independant sizes and colors. Yet, if I made a function in the class called "Draw" which magically drew it on the screen in the appropriate size and color that I had specified, I could call "Draw" for each object, and each shape would be drawn on teh screen. The same code is being executed for each shape, but with different values for the size and color, since each shape object is its own unique entity with its own size and color.

The whole point of classes is so that you don't rewrite code. If you needed to have 1000 shapes on the screen, it would be silly to write the drawing code out 1000 times, one for each shape. It's much easier to write a single blueprint that applies to all shapes.

That said, your code above has a number of "classes" at work.

The "Products" class is a class which stores information about a "Product". In your case, this info looks like it is the name of the product, it's price, how many are in stock etc.

The "Inventory" class is a class who's purpose it is to keep track of an array of products. There are a bunch of functions inside this class. I'll describe what they do below


The buildinventory() function appears to build up a list of products for use in the inventory. Notice how it calls the line:

product[0] = new Product(1, "socket set", 3, 19.99);
filling up the "product" array? Each call there created a new "Product" object which was based on the "Product" class. So each object has it's own name, inventory number, stock, price etc, but they all have the same set of functions to do things like, say, get the price of the product (the getPrice() function), or get the name of the product (the getName() function). It's the same function, as defined in the Product class, but when called on a different product object, it will return different results. This works well for an inventory program.

The "DisplayInventory" function loops through all of the products that the inventory class has created, and outputs information about each one to the screen. By the looks of it it is also keeping track of the total value of the inventory, in a variable called "totalPrice". Every time it loops through a product, it adds the product's price onto the total. The idea is once that while loop has finished, that variable will hold the final "total" of the inventory. After the loop has finished you can do a System.out.println() and use that variable to display the final total. This is probably part of what your project is asking you to do.

The "SortInventoryByName" function simply sorts the list of products that the Inventory class has created based on the name of the product. It does this using a build in Java class that you don't need to worry about.

You'll notice a function that is just called "Inventory()" near the top. This is called the "constructor". When you create a class, the class sometimes has to do a bit of initialization work before it is usable. This function is called as soon as the class is instantiated as an object somewhere in your code. So in this case, when you eventually create an inventory object, that function will be called and the inventory will be built (by calling buildInventory()), sorted (by calling sortInventoryByName()), and displayed (by calling displayInventory()).

------------

So it looks like you have this great Inventory class that does everything you need it to do. So now what? It still doesn't do anything! The reason is because it itself is just a class. It's a BLUEPRINT for an inventory. You need a Java program to USE the inventory class to actually do something useful.

You need to make a java program with a sub main() in it (just like every program you've ever made in this class). And inside there initialize a new inventory object, just like how the inventory object made product objects.
e.g.
Inventory myInventory = new Inventory();

Remember the Inventory() constructor! It will get called here, and the inventory class will go ahead and build an inventory, sort it, and display it on the screen.


So hopefully this will help you to understand your class a bit better. Again, real programmers don't just take classes and use them, they need to understand how they work. It's true that occasionally you can find something that does what you need it to do, and you don't need to "Reinvent" the wheel, but if you are unable to understand what it is doing, you can never modify it or tweak it, and if your problem isn't perfectly solved using the class, the class is useless to you. Programmers write their own modules and re-use them as they see fit, and occasionally they use someone else's code as a template. This is why you are learning how to modify an existing class.
