Opening Multiple Tabs
Sep 27, 2014
I'm now working more and more on the go and although I can carry my Macbook Air without too much trouble I've just been given an iPad Mini by work and it's far easier to do what I do with that on the move.
For work I need to open around 35 different websites at one time 4/5 times a day on the move.
With my Macbook that's no issue, as I can just use the open all function of my bookmarks, but on the iPad there is nothing that will allow me to do this.
I have looked online and a few people have had this issue and fixed it using the below Java method:
Creating a link that when clicked sets off a Javascript function that contains several window.open("url"); Clicking the link opens each website in its own tab.

I'm going through a file (MySQL dump) and I wish to take the SQL and create individual files for each table (as opposed to what I do now, which is just run through the whole thing).
<code>
BufferedReader myDumpfileReader = new BufferedReader(new FileReader(tfDumpfile.getText())); BufferedWriter myDumpfileWriter = new BufferedWriter(new FileWriter("/users/linehanp/mydb/bin/tgac_dump/Vanilla.sql"));
while((dumpFileLine = myDumpfileReader.readLine()) != null){ DoStuff();
MyDumfileWriter.write("Whatever");
}
myDumpfileReader.close();myDumpfileWriter.close();
</code>
Now, this all works fine - but what I want to do is create a separate .sql file for each table.
However, I can't figure out the best way to do this - how do I create a new FileWriter (or instance of whatever class is required) as I'm going through the while loop? That or pointing the same one to different files as I go through the loop.
It can be assumed that the file may exceed RAM - I want to do it line by line rather than slurping the entire file as a string and "cheating" that way.
There appear to be many (a bewildering amount of) I/O options and I'm just unsure.

I have a string from which I need to remove all of the newlines, tabs, and spaces. Here is the code I wrote:
inputString = inputString.replaceAll(" ", "");
inputString = inputString.replaceAll("
", "");
inputString = inputString.replaceAll(" ", "");
It removes the spaces just fine but not the newlines or tabs. How can I do this?

how to use a Primefaces TabView for input.
I have found this link that implements the behaviour of the TabView. It basically says to make my own Tab model.
But I want each tab to contain something like this:
I tried adding the inputTexts in my Tab model but it doesn't work, I guess I was way too optimistic :P
The only reason I want this is because I don't know how many tabs I need. It's totally dynamic, the number of Lectures is added on demand.

I'm looking for a way to put a tabs on a TabPane starting from both sides on the same edge.
Imagine having 3 or 4 tabs at the top left as in the default behavior, and one at the top right for some "special" features.
Is there a way to do it? Or is something expected to exist in the future? (or not at all?)

I am creating a simple code in Java that replaces all tabs the user inputs with '*'. However, I am doing something wrong and I am not sure what. Here is what I have so far in Eclipse..
import java.util.Scanner;
public class ReplacingTabs {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
String s = "";
String s2 = "";
[Code] .....
There is an error with the s2 in the line String s2 = s.replace(' ','*');
I think I need to add String s2 to the loop but I am not sure how..

I have created a java gui application and I need to communicate through the serial port. I would like to open the serial port in the beginning of the application and then close it when the applications closes. The problem that I am having is that I created a method to open the serial port in the main function but I can not close the serial port on exit off the application. Is there away of having the serial port be setup so that all methods can access the serial port.

We are creating a quiz as a school program, we are using netbeans and we have a little problem. The problem is that our JButton opens a new JFrame in a new window and we want it to stay in the same window. The code we are using is:
private void PlayButtonActionPerformed(java.awt.event.ActionEve nt evt) {
Question1 s = new Question1 ();
s.setVisible(true);
}
Is it possible to make it stay in the same window?

I have a package (JAR_A) for entity and controller definition, for example:
entity: Entity
controller: EntityController
Then I use this jar in other projects/applications that use the entity.
I want to use the same JAR_A with different persistence unit and different database (in particular, mysql and postgresql) but when I define two persistence unit that include the same class, I have an exception.
So, I comment the other PU and compile the project.
there is a smarter way for use same package with different PU ?

I am trying to launch a GUI to my agent-based model (Repast and Eclipse) so that being able to run the model for many times. I am going to produce input parameters based on different distributions for different runs from GUI. Usually we should use batch file for different runs. However, I want to use GUI for this reason because I have GUI that can take care for one run but not for many runs.

For example, if I have a class called Teacher with the constructor:
public Teacher(double yearsTeaching, boolean isMale, double age)
{
this.yearsTeaching = yearsTeaching;
this.isMale = isMale;
this.age = age;
}
How would I add it to these parameters to my ArrayList in my Tester class?
List<Teacher> teachers = new ArrayList<Teacher>();
