How To Extract Specific Part Of A String In Java

Mar 1, 2014

consider this statement from a jsp file(there are many more statements like this in jsp file..) Statement -

<h:dataGrid something styleclass="styleclass1" something1
onClick="event" something2
<% this is a scriplet tag %>
something3
style="style1">

<h:output text>hello i am text</h:output text>
</h:dataGrid>

What I want is to extract(and store it somewhere) the part from "<" to ">" where:

< - is the one in "<h:dataGrid"
> - is the one in "style1>" and not the('>') one that appears in the end
of "</h:dataGrid>" or "<h:output text>" or "</h:output text>"

Problem is the text b/w && is in multi-line...&& there are scriplet tags in between them.. so i don't know how to extract this particular string.. i tried using using some regular expressions but couldn't find the exact one..

(this was just an example && instead of this "" tag it can be anything like again in this line :

<h:output text>hello i am text</h:output text>

I want to extract the string from "<" till ">" where :

< - is the one in starting of "<h:output text>"
> - is the one in ending of "<h:output text>" and not the one in "</h:output text>"

However the difference b/w this example and the above mentioned one is that this one is not multi-line and doesn't contains any scriptlet tags)....

Implementing Java Project With Android

Nov 19, 2014

I have a gameengine stil partially in the works for pc made in java, I am attempting a port over to java but certain classes and other fuctions are not available for android that there is in java. this means that my render engine, gameengine and a couple of other clases therefore don't work.

My question is, is there anyway of using the gameengine classes that work into the project so that all i have to do is declare within the engine what i want to export for wheather this is android or java. or importing packages from the game engine project and directly linking with the ability of re-writing the odd few classes that do not work.

Extracting Eclipse Project As Runnable Java Not Working

Feb 5, 2014

I've been working quite a bit with a login system the past couple of months and I now have a version that I would like to try "for real" by extracting it as a runnable .jar or .exe file. I've looked at a couple of guides that told me how to do this properly, but even after following every step precisely it didn't work.

One of the guides I tried: 3 Ways to Create an Executable File from Eclipse - wikiHow

Double clicking the file or selecting it and pressing enter does nothing, the computer loads for a second and then nothing happens. I don't receive any visible errors when extracting the program, either.

However, when running the file from the command prompt I do receive an odd error:
Microsoft Windows [Version 6.2.9200]
(c) 2012 Microsoft Corporation. All rights reserved.

C:UsersUserName>java -jar Login.jar
Exception in thread "main" java.lang.IllegalArgumentException: input == null!
at javax.imageio.ImageIO.read(Unknown Source)
at LoginSystem.Data.updateData(Data.java:347)
at LoginSystem.Data.<init>(Data.java:309)
at LoginSystem.MainFrame.<init>(MainFrame.java:42)
at LoginSystem.MainFrame.main(MainFrame.java:457)

C:UsersUserName>

I must say I don't quite understand the error, it seems to be unable to load an image which is odd considering the program works fine without any errors at all in Eclipse.

Java Project - UPC Calculator / Calling ToString Method?

Feb 20, 2014

Our goal is to write a pretty simple program, one that takes the 12 digit UPC code entered by a user and to not only spit it back out in a format with dashes using toString, and also returns the first digit, a 2 more groups of digits numbering 2-6 and 7-11, and finally display the 12th digit. It then performs an equation to check the last digit and make sure the UPC code is correct.

However, being so new to java (I only learned visual basic before), with this I was introduced to two new concepts that for some reason I simply cannot grasp for the life of me: Using and calling the toString method, and calling on methods that are created in a completely different class file.

The first section of code is my UPC class, which is meant to contain all my methods as well as the toString to be called on:

public class UPC
{
// Instance variables
private int itemType; // digit 1
private int manufacturer; // digits 2,3,4,5,6
private int product; // digits 7,8,9,10,11
private int checkDigit; // digit 12

[Code] .....

Java Swing Project - Updating Labels And Other Stuff

May 28, 2014

I wrote a simple random spelling game for a class project, was never able to get the labels to update when they should. I have tried .updateUI, .paintImmediately followed by .revalidate and by .repaint. Nothing seems to be working.

What the game does is show a random word for about 10 seconds, disappear and they user is to spell that word, you have 3 tries then will start over. The "brains" of the game work just fine, it is the labels updating with new text when they should doesn't seem to be working. There is 4 classes but the below is the "Main" that has the problems. Also have a null exception problem with the timer.stop(); not sure why. I am still pretty new to java.

Public class SpellMe extends JFrame {
// variables
JPanel mainPanel, secondPanel, thirdPanel;
JLabel mainLabel, wordLabel;
String spWord, sp;
JTextArea guess;
