How To Take Different Actions For Different Ranges Of Data
Mar 18, 2014
My professor like us to make a salary, taxes and etc exercise. which we should type the name first then, input salary. then if we input the amount 8000 or higher. the system will ask another question about the marital status. and that is it.
My real problem is when we input 5000-7999 the system should ask a different question, stating do you want to pay for your premiums and a follow up of yes and no choices. if we input 0-4999 the system will just state that it is your current salary.... etc..
package exer5;
import java.util.Scanner;
public class Exer5 {
public static void main(String[] args) {
Scanner Kirk = new Scanner (System.in);

I am trying to make a calculator that ranges from simple math to trig. I am trying to start the j-frame for it and I already have most of the formulas programmed with the if-else statements and such. How do I go about starting the jFrame and marrying the 2 codes together to start it. (I have taken a bit of programming but relatively new to writing j-frames and using other classes and putting them together).

How do I add actions to the buttons? So when the button is pressed it will appear in the text area?
Where do I put these commands also? Within public void gui?

When I add an array of action-objects (the class extends AbstractAction)
to a combo box, I do receive the action performed events, great!
But the combo box items show the long string of the action object, of course!
How to render that string in a way that only the Action.NAME appears?
I was experimenting a little, but could not make it to work:

I have spent quite a few hours trying to follow an API on how to use Actions in a java program.
I have 3 JButtons and have just added a JMenu. What I want to do is to add an ACTION so that the JMenu performs the same function as the JButtons. (i.e. they both do the same thing).
I have tried to copy and follow the example from the API forum.
How to Use Actions (The Java > Tutorials > Creating a GUI With JFC/Swing > Using Other Swing Features)
The first error I get in compiling is on the following line:
Action loadFile = new LOADFILE();
However, I get the following error message:
softeng2final2.java:49: cannot find symbol
symbol : class LOADFILE
location: class softeng2final2
Action loadFile = new LOADFILE();

How to get my program to display a piece of text (upside down) on the first button press, and then display it right-side up on the second button press. I've looked all over the internet and I can't seem to find a example that fits my situation.

I have read that when two threads have two steps (of execution) and each step involves many operations, then the operations of both the threads kind of overlap one-another. For example
I think I am not very clear about interleaving actions/operations? Especially when we say that atomic actions can not be interleaved. But
Java Code:
class Counter{
private int c=0;
void increment () {
c++;
}
void readIn () {
[Code] ....
And the following sequence of events occurs.
Thread A: Retrieve cThread A: Increment cThread A: Store the result in cThread B: Ask the user to enter a valueThread B: Read in the value, store it in c
Now the value of c obtained after increment will be lost (Thread Interference). Isn't this an example of interleaving operations?

I was tasked to do a 2-4 player network card game. Before I jumped into doing the card game. I decided to try out an a simple program which is the clients taking turns to type in their textfield.
I have a server that listens to 3 incoming client connections. once all 3 clients is being connected,
Steps
1) The first client will send the message first while the second and third client will wait for the first client to finish sending.
2) After the first client finished sending the message, it will be second client turn to send the message and the third client will wait for the second client to send finish.
3) After the third client finished sending the message, it will be third client turn to send the message and the first client will wait for the third client to send finish and (go back to step 1))
**The first client can only start typing once all 3 clients is being connected**
In my server class,I spawn a new Thread once a client is connected, I do a wait() on each time the client is being connected, I stored the thread in a arraylist as well. I have an id to keep track how many clients is currently connected. once the id reaches 3, I used notifyall() to notify all the threads and set the first position of my arraylist as my currentThread so that I can keep track which is the currentThread running.
I started 3 clients. and I typed the textfield of the first client but my server isn't receiving any messages.
class Server implements Runnable {
private List<SpawnNewThread> sntList = new ArrayList<SpawnNewThread>();
private SpawnNewThread currentThread;
private int id = 0;

<f:facet name="header">

</h:panelGroup>
</f:facet>
<f:facet name="controls">
<h:outputLink onclick="#{rich:component('createManagedObject')}.hide(); return false;">
[Code] ....
As shown in the above code:
I have following components in ModalPanel:
1) ComboBox
2) Instance
3) Save and Cancel
I wanted some validation here :
For example:
- The Instance Text box and SAVE button should be disabled. When the pop up appears.
- The Instance Text BOX gets enabled only when any selection happenes in COMBO Box
- The SAVE button gets enabled only when COMBO BOX and INSTANCE TEXT BOX is filled.
- Let the CANCEL button be enabled always.

success case
---------------------------
i/p------<aaa><bbb>This converts string to xml</bbb></aaa>
o/p---<aaa><bbb>This converts string to xml</bbb></aaa>
Failer case
-----------------
i/p----<aaa><bbb>This fails if it contains < symbols</bbb></aaa>
expected o/p----<aaa><bbb>This fails if it contains < symbols</bbb></aaa>

Is there a way to inform the Entity Manager or force the JPA provider to reload data from the database? The scenario could be data being updated by a store procedure or direct SQLPlus maintenance, without restarting the Application Server, the JPA need to load the newly updated data from the database.
I think the current JPA API is not enough. The void refresh(java.lang.Object entity) from EntityManager need to pass in the Entity object, I will like to know how to refresh the entire JPA Entity data after the physical table data being update from backend.

By using FileReader, FileWriter and their constituents, I am creating a file to contain employee information ( name, age, hours, etc. ). The user is to input all of the data on a single line and we were asked to implement StringTokenizer to assign that data to the file. I have never used the StringTokenizer before, but I have a rough idea how it is to function. I used pw.println to test what I have so far, now I would like to let the user build the initial file with the "first employees" of the company, and then view the file, and then go back and append new employee data to that same file. My question is, how can I take the user input as a StringTokenizer and add that to the file?
In the for loop below, I thought I would see if it would work, but it does not. The loop only executes once and does not allow me to enter data.
public class Records {
public static void main(String [] args) throws IOException {
Scanner input = new Scanner(System.in);
FileWriter fw = new FileWriter("dbs3.java");
BufferedWriter bw = new BufferedWriter(fw);
PrintWriter pw = new PrintWriter(bw);
System.out.println("NEW EMPLOYEE DATA SHEET");
System.out.print("Number of new employees: ");
int number = input.nextInt();

I am using apache-commons-fileupload to get file from client to the server.(using JSP and Servlet).
JSP/HTML
<form method="POST" action="GetFile" enctype="multipart/form-data">
<input type="file" name="datafile">
<input type="text" name="text1">
<input type="submit" value="Next">
</form>
Servlet: GetFile
System.out.println(request.getParameter("text1"));
I am able to upload the file to the server, but I am not able to get the value of text1 in the servlet (I am getting null value of text1 in the servlet), I need this textfield in the form to submit some additional information while uploading it to the server.
--> Is enctype="multipart/form-data" option of form doesn't allow other form data to be submited? if it doesn't allow it then what are the other options I have to send this additional textfield to the server.
--> Or is there any other problem in my code?

I have written several simple data classes that I serialized manually by converting to text. At this point I need to serialize a more complex data structure. which will include lists of the simpler elements. Can serialize store and reconstitute this type of structure automatically or do I need to do this one manually as well? Consider the pseudocode below for a clarification of my question;
Java Code:
Class Hops{
String Name;
float Alpha Acid;
float Beta Acid;
};
Class Malt{
String Name;
float extract;
};
Class Recipie{
String Name;
CList HopList;
CList MaltList;
};
CList RecipieList; mh_sh_highlight_all('java');
I read the article on Serialization presented at tutorial point, but the example only showed a simple class, not lists of class members. What I want to do is serialize RecipieList, which consists of a CList of Recipies, which in turn consist of CLists of various ingredients.

I have a program which consist of several classes. The program reads a pom file and parses the data and then writes the data to a static table. The issue I'm having is with writing my LIB file data to my table. In the HtmlDataTable Class Im trying to write the files that are read in the lib directory to the table. My table currently consist of 3 columns (missing jar files,Lib Directory files, and POM file data) currently Im only able to write the missing jar files data to my table. In the HtmlDataTable class there is a for statement where I write the missing jar file data to my table. Im also trying to write the contents of the Lib directory within this statement as well. This is where I'm having my issue. My other classes consist of a SAX parser which parses the xml file, a class that creates my static table and a class that compares the jar files in my lib directory to the jar files in my pom file. . Theres a lot of code so I included the parts I felt were useful. If needed I can include the other classes as well.
public class ReadPomFile extends DefaultHandler {
public static void main(String[] args) {
try {
// obtain a SAX based parser to parse XML document

Java Code:

My issue is that the 'str' value is not initialized, but if I initialize it, it ruins the code. I'm not sure what to do in the situation.

write a program that will take in a URL as input and then search through the text on that webpage to pull out relevant data.Essentially, my plan was to have the program search the webpage on certain strings and then find and record the numbers on the same line to compile into another file. Luckily, all of the data I need are in tables on the webpage so I assumed that would make it easier to get the data.
The problem that I am facing is that I do not know where to start. I have been searching the web for answers to this but, unfortunately, the only thing people tend to recommend is using an HTML parser. This would not work since HTML code is not what I am looking for and does not include the data I seek.
