String to Object, then get the Class

hi I'm new in Java!
what I want to do is to convert a String and convert it to a Object then get the classname of the Object.
for example:
ExampleClass classObject = new ExampleClass();
String exampleString = "classObject";
I want to convert the string "classObject" into an Object, then get the Class name of the Object. (Let's just say I don't know what the Class name is)

static Class forName(String className)Please correct me if I'm wrong...
but what I have is an Object name (in string format),
not a Class Name.
So I'm kinda looking for something like...
static Object forName(String objectName)
Class.forName() returns a Class object. From this you can create an instance.
String s = "java.awt.Frame";
java.awt.Frame frame = (java.awt.Frame) (Class.forName(s)).newInstance();

I would also like to know how we get the DOM object ID for particular item.Use firebug or inspect the source code of the rendered page to see the object IDs. Other then then, the typical ID of page items is the name of the item. For regions you can set your own ID.

How to get the Class name of an API method?

Like most of us, it's difficult to know where every method within a Java class is. Also, many of the same methods are scattered throughout Java Classes. I know of two methods that retreive this... getClass().getName(). But, you must have an object to use these. Is there a way to find out what Class contains a method or Class variable thru an Applet or Java Application?? Obviously, I can look at API Docs; but this takes time.
Tks Randy

I need get the class container name (Urgent)

My class contain another inside, declared as variable.
In the class declared as variable, can I get the class name of class that contains it?
Is it possible?
Thanks
Renato de Melo

I can't think of a good way of doing this, but here is a really kludgy one!
within FieldClass, use getClass().getName(). This will return the full name of the class, and since this is an inner class, it will be "packagename.Container$FieldClass". All you then need to do is to find the substring between the last full-stop (period if you're American), and the $:
String className = getClass().getName();
int start = className.lastIndexOf('.') + 1;
String containerName = className.substring( start, className.indexOf('$', start);HTH (and HTW - this is off the top of my head!)

Get the class file name of the JSP page

Hi
I'm wondering how I can get the class name associated with the current JSP page...
I found on this forum how get the name of current JSP page, but it doesn't help me...
Thanks

Hi,
Sometimes I can be really dumb; of course, the solution is to call the getClass() method on the this object, and eventually store the Class object returned in the SessionBean file if it's necessary (in a SessionBean field/property, or in a parameter of a SessionBean's method).
Sorry for this thread without any interest. :(

How to i get the class name ? please help me

hi friends
i want to know how to get the class name from my java program
public class sample
public static void main(String args[])
how to i get sample.
please help me.
thanks in advance

I can't recall which forum member gave the following solution, but it works
in static contexts and it's copy-and-paste friendly -- you don't hard-code the
name of the class, only a dummy class that you use to make this hack work:
public class Foo {
    private static class Dummy{}
    public static void main(String[] args) {
        Class cls = Dummy.class.getEnclosingClass();
        String name = cls.getName();
        System.out.println(name);
}

Do you know of a good book about the "middle ground" (ie, these service layers)? I understand it empirically, but haven't had a lot of exposure to it.

PS: Apologies. Edited my previous post, presumably while you were composing your reply, when I finally realized what '.filed' meant.Most of my work is in web development, never been a DBA :) . The biggest 'concern' in my shop is 'separation of concerns'. The UI group reports up to a different IT head, the DB group reports up to a different IT head and so on. The looser the coupling between these systems, the lesser the project costs (Integration, QA etc) are. Martin Fowler's books contain good information about separation of concerns in an enterprise environment. The two books which i recommend are

Get the Class of something i have in mind

i found 2 ways of getting the class of a type
1. return Class.forName("Boolean");
2. static Boolean aBoolean = new Boolean(true);
return aBoolean.getClass();
the first one throws an exception and in the second one i have to create a random object. is there a nicer way to do this?

You have to use the fully qualified class names with Class.forName... for Boolean it is java.lang.Boolean.
Two ways that don't create unnecessary objects:
1. return Class.forName("java.lang.Boolean");
2. return Boolean.class;
and if you wanted the class of the primitive type boolean you can use Boolean.TYPE or boolean.class...

Getting the class of a primitive type or void

Hello,
Class.forName cannot be used to get the class of a primitive type or void. What does then ???
I thought of defining a class for each primitive type and override getClass() to return the required type, but getClass() is final ...
Please help

I don't understand what you mean e.g.I get the name of the primitive type at runtime and need to convert it to a class. For example, Class.forName("byte") returns byte.class. But, unfortunately, Class.forName() doesn't return classes of primitives or void.
I already solved the problem through putting ptimitive classes in a hashtable. But I was wondering if there is a simpler solution !!!

When I turn on my iMac it comes up with the icon which I then log into. The password works and I then get the apple icon and the spinning wheel. After a minute it turns into a prohibited icon. If I log on the guest icon I get to Safari. Help!

When I turn on my iMac it comes up with the login icons which I then choose and log into. The password works and I then get the apple icon and the spinning wheel. After about a minute the Apple icon turns into a prohibited icon. However, if I log in under the guest icon, I can access the wifi and get to Safari. I really don't know what to do next. Any help would be gratefully appreciated.

Are you running any A-V? If it's an iMac 21.5, I don't think you're running Leopard, 10.5. Probably at least Snow Leopard, 10.6. This is the Leopard forum.
This article says meant for 10.3.9 and eariler, but contains some still useful suggestions.

Try a Safe Boot. Shift at the startup chime and expect a much longer time to boot. This will bring you to a login screen with "Safe Boot" in red.
Look at this as well.

I'm new to Mac and the program/all called Numbers. I'm trying to use both Average and small in the same formula. What's I'm trying to do is take 20 cells, find the 10 lowest numbers, then get the average and after that multiply it by .96

I'm new to Mac and the program/all called Numbers. I'm trying to use both Average and small in the same formula. What's I'm trying to do is take 20 cells in a column, find the 10 lowest numbers, then get the average and after that multiply it by .96 I used to use Excel and the formula worked fine in that. Here is my Formula
=(average(small(H201:H220,{1,2,3,4,5,6,7,8,9,10})))*.96
This formula worked in Excel and when I converted my spreadsheet over to Numbers, this formula no longer works.
The best that I have been able to do so far is use small in 10 different cells, then get the average of the 10 cells and finally multiply that average by .96 So instead of using 1 cell, I'm using 12 cells to get my answer.
This is a formula that I will be using all the time. The next cell would be =(average(small(H202:H221,{1,2,3,4,5,6,7,8,9,10})))*.96
Hoping I explain myself well enough and that someone can help me.
Thanks

You can still do it in one cell but it will be more unruly than the Excel array formula.
=average(small(H201:H220,1),small(H201:H220,2),small(H201:H220,3),...,small(H201:H220,10))*0.96
where you would, of course, replace the "..." with the remaining six SMALL functions.

Divide a string in order to get the distinct list level.

Hi,
I want to divide a string in order to get the distinct list level to relate this with a category table.
The size of my list is dynamic and because of this I’m unable to find a way to do this!
Here goes an example of what I need to do:
Consider the following list:
Category                Category_ID
Age                     1
Less than 3 months      1.1
Less than 9 months      1.2
Less than 1 year        1.3
Risk                    2
Danger                  2.1
High                    2.1.1
medium                  2.1.2
low                     2.1.3
If I have a row that has category_id "2.1.3" I want to present values as:
"Risk.Danger.Low"
If I have a row that has category_id "1.1" I want to present values as:
"Age.Less than 3 months"Any hint on what I should search in order to accomplish this?
This will be used to produce a report. This report will contain a few thousand rows and the categories will be around 100.
Thanks,
Ricardo

How to get the .class file for the extended Controller .java file

Hi,
I did the below steps.
1. Created New OAWorkspace
2. Created New project
3. Imported the page .xml file
4. Added new .java file by extending the controller class
5. Added code in the .java file.
6. Ran the .xml file
As I copied all the folders from Unix box, the page was opened.
But My question was where can I see the .class file the extended controller. It's a .java file. How to compile and get the .class file for this .java file. If I get this .class file, I can go to the page and click the personlize page. and change the Controller name to the new path by ftp ing the new class to the cust.oracle.apps.pos.changeorder.webiui.
Please let me know how to create the .class file.
Thanks,
HP

All are Java files are stored in JDEV_INSTALL_DIR:\jdevhome\jdev\myprojects\
In your case the path java would be
JDEV_INSTALL_DIR:\jdevhome\jdev\ myprojects \cust\oracle\apps\pos\changeorder\webui\
AND
Once you compile the java file in Jdeveloper, Class files get generated @ below path
In your case the path of class would be
JDEV_INSTALL_DIR:\jdevhome\jdev\ myclasses \cust\oracle\apps\pos\changeorder\webui\
