Search in Java Documenation

Is there a program that can find info in java api documentation. For example, I input a name of class and this program gives me links to all files of documentation that have links to this class. Like MSDN documentation does.

Is there a program that can find info in java api

How to do exact word search using Java API

Hi,
Can someone tell me how can I write a search query using Ultra Search Java API to return data containing a full word that is sent as a search
parameter. e.g. If I want to search for a word 'Dictionary' I need to get all the results conatining full word Dictionary for example if I
have following 4 records
1. Dictionary
2. English Dictionary
3. French Dictionary
4. AllDictionary
How can I write a query that returns me first 3 records only as they contain the word 'Dictionary' and not the fourth record as it's not a word.
Here is what I need to get back and ordered in that way as the 'Dictionary' needs to be first record because the search is on Dictionary.
1. Dictionary
2. English Dictionary
3. French Dictionary
Any help is appreciated.
Thanks

Looks like we can not do an exact word search using Java API.

How to search inside java code?

How to search for pattern in Java code from NWDS? For example, I want to search for "wdThis" in java code. Where to look for find or search button?

Hi,
You can also use CTRL+H key for searching any Java or non-Java code across all projects you have opened in your workspace.
Just go to Project Explorer View and select any project, then press CTRL+H, a set of search option will show up.
Hope it helps.

Hi,
Just giving you an idea to solve this, but implementation of this depends on your hardwork.
We can use Threads concept here. Use a integer variable, which is a global and is used later.
Now TWO java threads are activated.
One of the thread will constantly pool the Standard Input device for desired key value. Once it gets the desired key press value it will increment the integer variable.
The Second thread will serve as the searching thread. This will contantly check the value of the integer variable and the search string variable. If the integer value is more than 0, then this thread will run a methos which will point to the next occurance of the search word. After this it will decrement the value of the integer variable.
You may need to use Synchronization concept also in this when it comes to integer variable.
Hope this idea helps.
Do let me know once u implement the solution.
Cheers.

Search in Java

Hi, i want to create a search facility in java. What I want is to have a facility of entering a word to search(it will read a dictionary). and secondly I want the user to be able to click on a letter so that all the corresponding words appear. for example A,B,C,D,E,F,G,H.....
can anyone tell me how this is done in Java please. thank you for your time.

Make what you wants with a JTextField and a JList below :
// The container
JPanel panel = new JPanel(new BorderLayout());
// The list of words available
String[] words = ...
JList list = null;
JTextField field = new JTextField();
field.addKeyListener(
     new KeyAdapter()
          public void keyPressed(KeyEvent e)
               String value = (String)list.getSelectedValue();
               if (e.getKeyCode()==KeyEvent.VK_ENTER)
                    // Set the field value to the list selection when enter is pressed
                    field.setText(value);
               else if (e.getKeyCode()==KeyEvent.VK_UP && list.getSelectedIndex()>0)
                    // Set the field value to the list upper value
                    String newValue = (String)list.getModel()
                         .getElementAt(list.getSelectedIndex()-1);
                    field.setText(newValue);
                    // Select upper element
                    list.setSelectedValue(newValue,true);
               else if (e.getKeyCode()==KeyEvent.VK_DOWN
                         && list.getSelectedIndex()<list.getModel().getSize()-1)
                    // Set the field value to the list next value
                    String newValue = (String)list.getModel()
                         .getElementAt(list.getSelectedIndex()+1);
                    field.setText(newValue);
                    // Select next element
                    list.setSelectedValue(newValue,true);
// Add field to panel
panel.add(field,BorderLayout.NORTH);
// Creation of the JList
this.list = new JList(words);
// Add a mouse listener
list.addMouseListener(
     new MouseAdapter()
          public void mouseClicked(MouseEvent e)
               String value = (String)list.getSelectedValue();
               if (e.getClickCount()>=2 && value!=null)
                    field.setText(value);
// Add a key listener
list.addKeyListener(
     new KeyAdapter()
          public void keyPressed(KeyEvent e)
               String value = (String)list.getSelectedValue();
               if (e.getKeyCode()==KeyEvent.VK_ENTER)
                    // Set the field's value to list selected element
                    field.setText(value);
               else
                    // When a char is typed in the JList, we add it to the field

Unable to search within .java files on windows xp

windows Search can't seem to find things in my .java files (like grep) on my Windows XP machine.
Here's what I do: In the windows explorer, I select a folder which has some .java files beneath it, and I select Search off the folder's popup menu. That brings up a dialog that lets me name to file to search for, and also a word or phrase in the file. I enter filename of "*.java" and it finds all the *.java files OK, but if I also enter a value in the "word or phrase in the file" field and do a search, then it always says "0 files found" (I enter a word that I know is in some of the java files). Search finds words OK in .html or .txt files, but not in .java files. Weird.
Is there some setting in the windows registry that affects how searches are done in .java files?

Follow the instructions in this article. I've runinto
the same thing, and the solution works.

...Looking at your binary search method:
public static int binarySearch( Comparable [ ] a, Comparable x)I see it expects to be fed Comparable objects. So, whatever you're feeding it, it's not a Comparable (ie: it doesn't implement Comparable), hence the CCE.It's even worse: if an A is a B it doesn't make an A[] a B[].
kind regards,
JosMy post didn't make much sense: if there were no Comparables provided as an argument, it would have thrown a compile time error. The problem lies in the compareTo(...) method.

Create Named Search with Java API

Hi,
is it possible to create or modify a named search with the Java API?
Best regards,
Roman

Hi Olof,
You can use the below code for searching a value in lookup table:
               ResultDefinition objResultDefinition = new ResultDefinition(Lookup Table Id);
               objResultDefinition.addSelectField(Lookup Field ID);
               StringValue [] objStringValue = new StringValue[1];
               objStringValue[0] = new StringValue("Value to search");
               RetrieveRecordsByValueCommand objRetrieveRecordsByValueCommand = new RetrieveRecordsByValueCommand(objConnectionAccessor);
               objRetrieveRecordsByValueCommand.setSession(strUserSessionID);
               objRetrieveRecordsByValueCommand.setResultDefinition(objResultDefinition);
               objRetrieveRecordsByValueCommand.setFieldId(lookup field id);
               objRetrieveRecordsByValueCommand.setFieldValues(objStringValue);
               objRetrieveRecordsByValueCommand.execute();
               RecordResultSet objRecordResultSet = objRetrieveRecordsByValueCommand.getRecords();
Now using the objRecordResultset in a loop you can get the record id by calling the getRecord(i).getId() method.
Hope this helps!!

Searches in java

hey all I'm glad to be back in school because i get a chance to learn new things about programming. And with that comes annoying questions i usually post for the senior members.
Here is what i dont understand about serching in java. What is better a linear search or a binary search? Also can you explain why it is better to use logofn to do searches?
Thanks,

hey all I'm glad to be back in school because i get a
chance to learn new things about programming. And
with that comes annoying questions i usually post for
the senior members.
Here is what i dont understand about serching in
java. What is better a linear search or a binary
search? Did you try googling for linear search and binary search? They are general CS concepts and not specific to Java.
Also can you explain why it is better to use
logofn to do searches?You mean O(log n)? Better than what? Certainly not better than O(1), but better than O(n! ^ 99). If you don't know why, google for big o notation.

> Do you know any program written in Java that go on the
internet
1) So you need some way to access the internet from Java.
> and search for data that we specify.
2) and you need to be able to search for data specified.
Okay, well I'll assume you already know how to write a simple Java command line program that lets you input data (say, as an argument). If not, you're going to want to tackle that before you go on to do internet-based programming.
The two requirements are that you can access the internet, and that you can search for certain data. Well, to search for certain data, you are going to need to write a spider/crawler that traverses across the web and records the information it finds, reporting back when it finds the target data. Why bother doing all of this when there are plenty of search engines already that will do this for you. One of the best search engines is Google, and Google is accessible via HTTP (world wide web).
So, really all you need to be able to do is access the internet and talk to Google. This isn't too hard. To access the internet through HTTP (letting you get in touch with Google), you may wish to investigate the java.net package as well as the org.apache.commons.HttpClient package.

In search of java class dependency utility

Folks,
We have developed a J2EE application where the "client" is a java
application. In other words, we have created a JAR file that a user
uses to launch our application. The manifest for this JAR file has a
"Main-Class" attribute, so the following command is used to launch the
(client side of) the application:
java -jar our.jarOur entire application (both client-side and server-side) consists of
several hundred classes. Our problem is that we don't have an accurate
list of which classes are client-side only, which classes are
server-side only, and which classes are required by both (client-side
and server-side). I want our client-side JAR to only contain classes
required by the client. Currently, we are simply bundling all the
classes into "our.jar".
I have found (and tried) several utilities, including:
http://depfind.sourceforge.net/
http://www.clarkware.com/software/JDepend.html
http://www.horstmann.com/articles/BetterCleaner.html
However, I don't think these are suitable. You need to supply a class
name, and they only tell you the classes that either depend on the
given class, or that the given class depends on. What I want is a
"recursive" dependency finder.
For example, let's say I have class "A". Class "A" depends on class "B"
(in other words, class "A" needs to import class "B"). Now class "B"
depends on class "C" and class "C" depends on class "D". Also, we have
class "E" that depends on class "A" (in other words, class "E" needs to
import class "A").
The tools I mentioned above will only return (at most), classes "B" and
"E" (when I supply them with class "A"), but what I really need them to
return is classes "B","C" and "D" (and not necessarily class "E").
Does anyone know how I can achieve this?
Thanks (in advance),
Avi.

ClassDep from jini provides the same functionality as GenJar but I have found it better to work with. You do not need ant to run it although it does come with an ant task. ClassDep.java has a public static void main (String[] args ).
http://java.sun.com/products/jini/2.0/doc/api/com/sun/jini/tool/ClassDep.html provides the documentation on how to use it.
