SAX Parser / Tags And Text Don't Line Up
Feb 9, 2015 how to use SAX Parsers. I've looked at a few tutorials and have the generals down. I have an xml file that the parser is trying to read. As you see below, at the start of each element, I add the tag to an arrayList of the tags. I create a stringBuilder to capture the text between tags, this won't work unless it occurs at the end of an element. If it occurs at the start, it never gets the chance to read the text.
This is where the problem occurs. For nested tags, like project, it reads the last nested tags' text and stores it in the text arrayList. Project may be the first indexed tag in the tags arrayList, but project's text is the fourth indexed element of the text arrayList. So when my test print the arrayLists by index, it gets thrown off. I want over tags to store a blank space in the text array, and at the same index of the tag its associated with. How would I do this?
I've tried overwriting the text arrayList, but couldn't get my logic thought out for how to determine if a tag was nested. I always ended up overwriting blank space to each element.

How To Write ID3 Tags Using MP3agic Library
Apr 22, 2014I am trying to write the id3 tags using mp3agic library. The problem is it does not update the id3 tags for the mp3 files which already contains id3 tags but it only updates the file that have id3 tags which are empty.
When i look at the newly created files, they contains the older tags. Then i wrote a script to access id3 tags through mp3agic
id3v1Tag.getArtist()
then it was showing updated tags.
Why it is showing updated tags even if they are not really updated in folder where i visits ?
Program To Scrape All Title Tags From Large Sites
Apr 9, 2015I am familiar with php, but I don't know Java. We need a program, that will be able to scrape large amount of title tags from large sites, fast. I've been trying Seo Spider by Screaming Frog, and Xenu's Link Sleuth, but these programs are not good enough. They hang up, they save all the data in RAM, I think, and after a relatively short period of scraping, they stop working, become unresponsive, and so on.
Somebody recommended me getting a custom made program in Java, which would be able to scrape title tags only, from large sites (I am talking 25 - 50 million pages or more). I was told that it would not have a graphic interface, or anything like that. Nothing like this is needed too, we just need to have title tags.
JSF :: What Tags Of Xhtml View Will Be Build As UIComponents In Server Side
Jun 8, 2014In order to create an xhtml view:
1. All jsf tags like datatable, form, etc.. will generate UIComponents in server side, right?
2. All non JSF tags will not generate UIComponents in server side, right?
3. If you want something in a view that will be the same across users and requests, I mean, It will not change like a label tag, it doesn't make any sense to create it with a JSF tag in order to save memory in server side, right?

View Replies View RelatedDifference Between Eclipse And JDK?
Feb 27, 2014I'm not sure if that's the right place to ask
But I am a bit confused:
I know that JDK means "Java Development Kit" , but isn't Eclipse the same thing? (so why it's called "IDE"?)
Or maybe Eclipse is a type of JDK?
Or actually JDK and Eclipse are 2 different things

View Replies View RelatedHow To Calculate Difference Between Two Dates
Oct 19, 2014I have been tasked with creating an invoice (school assignment). Part of the calculations is creating an interest depending on the amount of days between the current date entered, and invoice date entered (The program prompts the user to enter both the current and invoice dates by asking for the day, month and year).
We are also supposed to set the contructor to a default date of 1/1/1900.. but I don't know how or where to code that.
How to calculate the difference between the CurrentDate and Invoice. I have displayed the dates to the user as follows.
public void displayDate() {
System.out.println("
Today's Date: " + month + "/" + day + "/" + year);
}
public void displayInvDate() {
System.out.println("
Invoice Date: " + invMonth + "/" + invDay + "/" + invYear);
Difference Between LinkedList And ArrayList
Feb 19, 2014I have just begin to understand collections in Java. I read about the differences between LinkedList and ArrayList but have several doubts on it. I have mentioned them below
1) Why retrieving in ArrayList is faster then LinkedList?. Since both have the get method how does performance differ?.
2) How does re-sizing happens internally in ArrayList when a item is added or removed?. How slow this is compared to the pointer re-shuffling in LinkedList when a item is added or removed?.
Difference Between InputStream And InputStreamReader
Jul 11, 2014I read that InputStream is used for byte based reading it reads 1 byte at a time.And InputStreamReader is used for charcter based reading so it reads one charcter at a time so no need to convert this first to int then read it.Here is reading using InputStream.
input=new FileInputStream("D:/input.txt");
int c;
while((c=input.read())!=-1)
{
System.out.print((char)c);
}
and here is reading using InputStreamReader
input=new FileInputStream("D:/input.txt");
reader=new InputStreamReader(input,"UTF-8");
int c;
while((c=reader.read())!=-1)
{
System.out.print((char)c);
}
so what is difference between InputStream and InputStreamReader in both case i have to use a Int and then read it and at the end if I want to print that data I have to cast that with "(char)c".So what is advantage of using InputStreamReader?

View Replies View RelatedDifference Between Application And Applet?
Apr 13, 2014Can explain difference between applet and application?
What are differences in code? How to write application?
What are differences in use? I looked for some answers, but I can't understand what they are talking about.
For example:
Application:
Called as stand-alone application as application can be executed from command prompt
Applet:
Requires some third party tool like a browser to execute
But... While I export applet in exclipse I can use it without any browser, just like application(as I and avarage user knows it).
Ok, I understand difference like "Applets cannot read from or write to hard disk files."
So. What should I use while creating what?
For example, something as simple as windows calc, some 2d simply platformer, some more expanded app, like idk, spotify or media player or whatever?
Since after update 51 of java web applets are nearly useless(as I know, maybe I'm wrong?), what is better?
Can application have GUI or it is only applets thing(stupid question?)?
Where can I find any application tutorial? Everything that I found was for applets. Why?

View Replies View RelatedDifference In Days Between Dates
Dec 5, 2013I know this has been covered before but none of the answers made sense to me. I'm hoping there is an easy way to do this. I have 2 user inputted strings that I have converted to dates and I just want the difference in days.
My code :
import java.util.Date;
import java.text.SimpleDateFormat;
import java.util.Scanner;
import java.text.ParseException;
public class DateTest {
/**
* @param args the command line arguments
*/
public static void main(String[] args) throws ParseException {

Apparently I can't just subtract the dates like I would in VB.
