I have this problem,
I need to represent set in the following form
[L,R]
where L is the left hand-bound of the set , and R is the right hand-bound
each of L and R are a collection of sets
for example
L= [{1},{2},{2,3}]
R=[{1,2,3},{2,3,4}]
[L,R]= [{ {1},{2},{2,3} } , { {1,2,3},{2,3,4} }]
how can i do this in java
|

There are many ways that you could represent this depending on what you are trying to do. My initial thought is a 2 element array of sets of sets e.g.
Set s1 = new Set();
s1.add(1)
Set s2 = new Set();
s2.add(2)
Set s23 = new Set();
s23.add(3)
s23.add(2)
Set left = new Set{}
left.add(s1}
left.add(s2}
left.add(s23}
/*
* Prepare Right Side now
*/
Set[] allSets = new Set[2]()
allSets[0] = left;
allSets[1] = right;
Do the Sets in L and R have to be unique. Also why are you modelling the sets what do you expect to do with them. If it is a bit more rigid and you want to perform operations on the sets you may want to use a class to model them
e.g.
public Class LeftRightSet() {
private Set<set><string> left;
private Set<set><string>> right;
// Further manipulation classes
}
Hope this helps

Hi all,
I need to find the coordinates of the selected item in my JList. I'd expect this line of code to be defined in swing, but it's not.
selectedItemY = [JList Name].getSelectedValue().getY();
Any suggestion?
Thanks
Naz

How can I compile my java code without going to a DOS window?
Everything makes sense in someone's mind
|
|

|

I use NetBeans IDE where every function is visually available. So you never need to use the cmd. You can download it for free.

the best I ever used is definitely Eclipse:
Eclipse for J2SE[^]
Eclipse for J2EE[^]

The RAD is better.
but not free.

Hi,
I've followed this article (http://java.sun.com/developer/technicalArticles/J2EE/AJAX/[^]) to create a Java Servlet and retrieve data from it using AJAX. In this example the doGet method is automatically run and it gives me the required output, however I would like to have additional methods in this class returning different things that I can call on demand, how would I do this?
Thanks in advance

Hi, I'm currently working on concerning a student record with guardians/parents... im using the java ee framework.. I'm having problems on retrieving the data on our database(MySQL).. Here is what i did.. i have created a class to retrieve those data from the database..
my problem is that whenever i retrieve that data in my jsp page, it only shows this Ljava.lang.String@123EGa something similar to this..
<small><br />
CLASS PLARENTS .. <br />
<br />
package com;<br />

Hi Xiang,
I found, your program for Searching and replacing strings (TextRep.java) in a file very usefull. Thanks for posting it.
Explaing below a scenario which im working on :
1. My Program should read the file name, search string and string to be replaced from an xml file.
<cmvc>
<cmvcauto>
<filename>C:\cmvc\Readme.txt</filename>
<string>Following are the contents of this CD.</string>
<replace>Im chnaged : Following are the contents of this CD.</replace>;
</cmvcauto>
</cmvc>
2. Get the file, search for the existence of the string in tht file , replace the old one with the new string and save modified file in a diff location.
I thought of modifying your program to match my requirement. Since your program TextRep.java also takes a backup of the file....my issue of saving the modified file is also solved. I have a program to get the values from the xml file. Now im passing those values to ur program instead of args[0], args[1] and args[2].
i get the value of filename from xml file in the fashion :
NodeList textFNList = firstNameElement.getChildNodes();
System.out.println("First file name : " +
((Node)textFNList.item(0)).getNodeValue().trim());
Now i define a method "replaceString" and call it in the main program by passing the values that i get from the xml file :
NodeList textFNList = firstNameElement.getChildNodes();
System.out.println("First file name : " +
((Node)textFNList.item(0)).getNodeValue().trim());
//-------
NodeList lastNameList = firstPersonElement.getElementsByTagName("string");
Element lastNameElement = (Element)lastNameList.item(0);
NodeList textLNList = lastNameElement.getChildNodes();
System.out.println("Search String : " +
((Node)textLNList.item(0)).getNodeValue().trim());
//----
NodeList ageList = firstPersonElement.getElementsByTagName("replace");
Element ageElement = (Element)ageList.item(0);
NodeList textAgeList = ageElement.getChildNodes();
System.out.println("Replace string " +
((Node)textAgeList.item(0)).getNodeValue().trim());
replaceString(((Node)textFNList.item(0)).getNodeValue().trim(), ((Node)textLNList.item(0)).getNodeValue().trim(), ((Node)textAgeList.item(0)).getNodeValue().trim());
Below is the method defenition and the defenition is your program :
public static void replaceString(String fileName, String match, String replacingString)
{
try
{
// make 32k buffer for output
StringBuffer strOutput = new StringBuffer(32768);
// read input file into a byte array
//byte[] pInput = ReadFile(args[0]); This is the original line from your program
byte[] pInput = ReadFile((filename);
// make a backup copy
WriteFile(fileName +".backup.copy",pInput);
String strInput = new String(pInput);
Doing this modification, i get the below error :
C:\Documents and Settings\Administrator\Desktop\CMVC_Automation>javac fullSearch.java
fullSearch.java:107: cannot find symbol
symbol : method ReadFile(java.lang.String)
location: class fullSearch
byte[] pInput = ReadFile(fileName);
^
fullSearch.java:109: cannot find symbol
symbol : method WriteFile(java.lang.String,byte[])
location: class fullSearch
WriteFile(fileName +".backup.copy",pInput);
^
2 errors
My program starts with these lines :
import org.w3c.dom.Document;
import org.w3c.dom.*;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.DocumentBuilder;
import org.xml.sax.SAXException;
import org.xml.sax.SAXParseException;
import java.util.regex.Pattern;
import java.util.regex.Matcher;
import java.io.*;
import java.util.*;
Would really apreciate, if you could help on those errors. Thanks.

Can anyone tell me different between JRE 1.6 and JRE 1.5? And what is "Keep temporary files on my computer" option? When I un-check this option, my applet runs ok. But If I check this option, my applet sometimes hangs up. So, I guess this error is come by "Keep temporary files on my computer" option. JRE 1.5 doens't have this option.

They don't tell this error. So, I can't find the solution of this error. Thanks for your reply!
I've another question. Do know you how to uncheck "Keep temporary files on my computer" by code or script?

From the second time, my applet is ok.
So, I guess this error is come by "Keep temporary files on my computer" option. JRE 1.5 doens't have this option. My applet can run ok with JRE 1.5.
Can you please tell me difference between check and un-check "Keep temporary files on my computer" option? Do we have anyway to uncheck it by Javascript or code? I don't know why un-check "Keep temporary files on my computer" option is ok with my Applet.
Thanks!

We have developed a web-based application with JSP as front-end. Recently we observed that after taking one of the Windows Updates, few buttons in our application are not working. If I uninstall this particular update, buttons are working fine. When I say it is not working, it means that onclick action is not taking place.
Windows Update: KB956390
Also, our buttons are developed in VML.
I've given below some code snippets:
JSP
===
<html xmlns:zoniac="ZON">
.............
.............
.............
<zoniac:roundrect class="zoniac_roundButton" arcsize="0.9" fillcolor="#245f91" style='width:95px;cursor:hand' href="javascript:btnLinkClick('accountsNewCompany',document.accfrm)" strokecolor="#245f91" onselectstart="return false">New Account</zoniac:roundrect>
.............
.............
.............
</html>
Also, If I change the above "href" action into "onClick" event, it's working fine. But I want the action to be with href, since I cannot make this kind of change all over my application.
<zoniac:roundrect class="zoniac_roundButton" arcsize="0.9" fillcolor="#245f91" style='width:95px;cursor:hand' onClick="javascript:btnLinkClick('accountsNewCompany',document.accfrm)" strokecolor="#245f91" onselectstart="return false">New Account</zoniac:roundrect>
CSS
===
zoniac\:*
{ behavior: url(#default#VML)
}
.zoniac_roundButton
{ text-align:center;
padding-top:3px;
color:white;
font:bold 11px tahoma;
height:17px;
}

Anyone know where I can download this? I look on java.sun.com, but I didn't see it.
