Creating Object using Class.forName vs new

Hello,
Is there any difference between:
Class c = Class.forName("Foo");
Foo foo = (Foo) c.newInstance();
and
Foo foo = new Foo();
Thanks.

Instantiating object using Class.forName()

What is the difference between instantiating using Class.forName() method and instantiating using the new operator?

The difference is that you can use the new operator to instantiate an object, but you can't do it using Class.forName().
But seriously folks...
Presumably you're talking about Class.newInstance()--which often appears right on the heels of Class.forName().
New gives you compile-time checks you don't get with Class.forName(). If it compiles with new, then you know the constructor in question exists on the class in question.
With Class.newInstance() (and it's cousin (also called newInstance, I think) in the Constructor class), you can't be sure until you actually execute it whether that constructor even exists.
New requires you to know the class at compile time. NewInstance lets you defer the specific class until runtime.
New is simpler and more direct.

How to create an object of our own class by using Class.forName()??

how to create an object of our own class by using Class.forName()??
plzz anser my qustion soon..

Class.forName does not create an object. It returns a reference to the Class object that describes the metadata for the class in question--what methods and fields it has, etc.
To create an object--regardless of whether it's your class or some other class--you could call newInstance on the Class object returned from Class.forName, BUT only if that class has a no-arg constructor that you want to call.
Class<MyClass> clazz = Class.forName("com.mycompany.MyClass");
MyClass mine = clazz.newInstance();If you want to use a constructor that takes parameters, you'll have to use java.lang.reflect.Constructor.
Google for java reflection tutorial for more details.
BUT reflection is often abused, and often employe when not needed. Why is it that you think you need this?

Database connectivity without using Class.forName()

Hi,
Can anyone please tell how we can connect to a database without in java without using the Class.forName() method , and then how the database driver gets loaded.
Regards,
Tanmoy

Hi,
I recently wrote code that connects to a database without using Class.forName() in order to be compatible with Microsoft's JVM. I read about it here:
http://www.idssoftware.com/faq-e.html#E1
Basically, you create a new Driver object and use its connect method.
Here's what my particular code ended up being:
String url = "jdbc:mysql://localhost:3306/test?user=root&password=mypass";
Driver drv = new org.gjt.mm.mysql.Driver();
Connection con = drv.connect(url,null);

Is there any Similar between Class.forName() and new operator ???

Plz tel me is there any Similar between Class.forName() and new operator ??? i have been asked this ques in interview

You probably should have used the other thread:
http://forum.java.sun.com/thread.jspa?threadID=792678
To add a little confusion to the matter...Class objects are in fact objects. They're objects representing classes. So, in a sense, I guess, you could say they're similar -- in each you get an object. But in practice Class objects and all other objects should be considered semantically different unless you're doing some pretty unusual stuff. Also Class.forName is more of a factory method than a constructor.

ClassNotFoundException when using Class.forName(), thx

in a study app, i try to use Class.forName() to load any class then get its properties (fields, methods etc. vs reflect).
the (Frame based) app is in directory:
c:\app\StudyApp.class
there is a "Open class" button on the app, click the button, i use FileChooser to open any class file.
i.e. open a class (assume it is not packaged)
d:\dir\TheClass.class
coding in StudyApp.java is:
Class cls=Class.forName("TheClass");
now a ClassNotFoundException throws when call Class.forName() above.
it is easy to understand why throw the exception because i never tell where the class is. it is in directory
d:\dir
my question is: how to tell VM the directory.
the directory d:\dir can not be applied to -classpath when run java.exe StudyApp, because the directory is random one at run-time.
i tried to change System property (i.e. "java.class.path", 'user.dir" etc. none of them can fix the problem.
thanks in advance for any help

Diffrence between Class.forName() and new Operator

What is diffrence between class.forName() and new operator.Please tell in much detail.
Also about classloader.loadclass.
Suppose the class that we are tring to load with the help of class.forname is not compiled. Again if I make changes at runtime to that class will that get reflected.

What is diffrence between class.forName() and new
operator.Please tell in much detail.Class.forName loads a class. The new operator creates a new instance. Apple trees and apples.
Also about classloader.loadclass.Read the API.
Suppose the class that we are tring to load with the
help of class.forname is not compiled.Then you can't load it and get an exception. Read the API.
Again if I

Overview of Leave --- CREATE OBJECT: The class was not found., error key:

Dear Gurus,
Iam facing this problem that, when i try to open the Leave Overview from the leave request screen. it gives the dump with message
CREATE OBJECT: The class was not found., error key: RFC_ERROR_SYSTEM_FAILURE
this also creates a dump in the back end.
The same dump is appearing when i try to view the Check Documents for the same employee from PTARQ.
Thanks in advance
Ramnath

Hi ,
please find the following solution .it will definitely work .
If you leave configuration is done.
There was an incorrect data in your system. To do these please follow following process.
delete this request using
PTARQ> Delete documents (RPTARQDBDEl)
Please read the report documentation before
deleting the request but it should be safe as it is
a development system.
Please delete this with the above information or delete all
the records for the approver.
After this,, there will be some incorrect workitem in approver inbox.
You need to clear that also by Tcode - SWWL.
ALSO check the leave request workflow of that employee and if there is any error workflow lying in the workflow delete the leave request (which was created with error) Note down the id initiater ( which had error) and in the Test Environment for Leave request (PTARQ) gave the PERNR and delete the documents ( give the id iniater in the document status ).
To check the error work flow go to SWIA and check for that Workflow (Leave) raised by the PERNR at that duration ( check in IT2001 for the duration) and give it here.
After deleting it check in the portal for the leave request if any error is occuring when trying to apply for leave.

Why use Class.forName() ?

Why is it always adviced to use Class.forName( nameOfTheDriver ). Why dont we simply import the driver via the import statement ?
Please note that this topic is part of a bigger topic I published in Java programming about difficulties I had importing driver. See:
http://forums.java.sun.com/thread.jsp?forum=31&thread=147534
for more details.

Because using an import statement only tells the compiler about the driver. Class.forName() actually loads the driver when the program runs, which is what you want to happen.

How to use class.forName

I am trying to use Class.forName() from a string which is passed to me as argument.
Class batchClass = Class.forName(args[1]);
A jar file contains the class file for the string received above and I have this jar file in the manifest of my executable jar.
I get a class not found exception when I run my executable jar
Can some body give pointers..what could possibly be the issue.
The jar file is in my classpath
run script

nothing worked...
my manifest file also contains the path to the package..so does the classpath

Why can't i use class.forName(str) ?

Heys all i have this piece of code which is working fine:
*try {*
java.lang.Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
*} catch (java.lang.ClassNotFoundException e) {*
now the problem is that i was under the impression that i could use class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); but it wouldn't compile. does anyone know why is this so?

Class.forName() says "call the static method forName() that is defined in java.lang.Class". It returns a reference to an instance of java.lang.Class.
SomeClass.class is known as a class literal. It is not a member, not a field, not a method. It evaluates to a reference to an instance of java.lang.Class.
You cannot do class.something().

Need Help Loading Sqlbase Driver Using Class.forName(...

I'm having trouble connecting to a Sqlbase database on my PC. The problem seems to be with loading the driver with the "Class.forName" method. My source code (listed below) is in the "C:\My Documents\java" folder. I installed the Sqlbase driver in "C:\com\centurasoft\java\sqlbase" folder. The driver installation modified my autoexec.bat file to include the line "SET CLASSPATH=C:\com\centurasoft\java\sqlbase".
The epdmo database is in a folder on my D:\ drive.
It seems to find the SqlbaseDriver.class file, but for some reason it can't load it. I would greatly appreciate any suggestions as to how I can fix this.
With the line -- Class.forName("centura.java.sqlbase.SqlbaseDriver");
The SqlbaseEx.java program will compile, but I get the following error
when I try to run it:
Exception in thread "main" java.lang.NoClassDefFoundError: SqlbaseDriver (wrong name: com/centurasoft/java/sqlbase/SqlbaseDriver)
at java.lang.ClassLoader.defineClass0(Native Method)
at java.lang.ClassLoader.defineClass(Unknown Source)
... [several more lines like these]
at SqlbaseEx.main(SqlbaseEx.java:25)
With the line -- DriverManager.registerDriver(new SqlbaseDriver());
The SqlbaseEx.java program will NOT compile. I get the following error:
SqlbaseEx.java:21: cannot access SqlbaseDriver
bad class file: C:\com\centurasoft\java\sqlbase\SqlbaseDriver.class
class file contains wrong class: com.centurasoft.java.sqlbase.SqlbaseDriver
Please remove or make sure it appears in the correct subdirectory of the classpath.
Also, does the line -- String url = "jdbc:sqlbase:epdmo";
look OK? I've seen numerous examples and they all have some values separated by slashes //. Am I
missing something here that will bite me when I get past this driver loading error?
import java.sql.*;
// Create the ...
public class SqlbaseEx {
public static void main(String args[]) {
String url = "jdbc:sqlbase:epdmo";
Connection con;
String createString;
createString = "create table COFFEES " +
"(COF_NAME varchar(32), " +
"SUP_ID int, " +
"PRICE float, " +
"SALES int, " +
"TOTAL int)";
Statement stmt;
try {
Class.forName("centura.java.sqlbase.SqlbaseDriver");
// DriverManager.registerDriver(new SqlbaseDriver());
} catch(java.lang.ClassNotFoundException e) {
System.err.print("ClassNotFoundException: ");
System.err.println(e.getMessage());
try {
con = DriverManager.getConnection(url, "SYSADM", "SYSADM");
stmt = con.createStatement();
stmt.executeUpdate(createString);
stmt.close();
con.close();
} catch(SQLException ex) {
System.err.println("SQLException: " + ex.getMessage());

Thanks for the reply.
Upon further testing, I think my original post was slightly incorrect: if I use either of the following lines --
Class.forName("com.centurasoft.java.sqlbase.SqlbaseDriver");
or
Class.forName("centura.java.sqlbase.SqlbaseDriver");
I get the following error at runtime:
ClassNotFoundException: com.centurasoft.java.sqlbase.SqlbaseDriver
or
ClassNotFoundException: centura.java.sqlbase.SqlbaseDriver
It is when I use the line -- Class.forName("SqlbaseDriver");
that I get the long error message in my original post.
I don't understand why it can't find/load the driver. I feel like I've covered all the bases -- I've tried numerous variations of the driver name in the Class.forName method, my classpath variable seems to be set correctly. Does it matter what folder I compile my program in? Right now, I've just been compiling it in the same folder as the driver file -- c:\com\centurasoft\java\sqlbase.

Sam

Austin,
Sorry for asking the basic questions.This is what i am doing. I went to DC, right clicked on it and selected properties. Then select JAva build path opition and then select Libraries. There i click on Add External JARs and select com.sap.security.api.jar.
and click ok.
do i need to do anything else here.
And when ever i come back after a while i see that the external
Jar is missing. IT looks weird. I have to keep on importing the external JAr after every few operations.
Not sure what the problem could be
thanks a lto for your patience in helping me ou ton this issue

Creating objects using reflection

Hi,
I need to construct a new instance using reflection and passing parameters. If the parameters are of primitive type ex. int, how can I pass them in the Class[] type of object

Integer.TYPE, etc. are Class objects that represent the types of the primitives.
