View Replies View RelatedI am trying to get items to display that would display in a command prompt now into a GUI. I am freaking lost at the moment, probably because I've been staring at this code for over a week now. I have included all the files that are necessary to run the program as an attachment for your own testing purposes. Should I be using a TextField to display the data from the CSV files? How do I get the data to be displayed? How would I get it to be displayed based on the different files Staples (newSTPL.csv), Apple (newAPPL.csv), and Microsoft (newMSFT.csv)?

I have a project in java that asks me to load some information from previous object files and add new objects to them afterwards. I created the files, but when I close the program and search for the previous information that should've been saved in the object file , it return nothing.
Here is the code.
Add method:
public boolean addUser (User u){
users[Ucount]=u;
Ucount++;
return true;
}
The save method:
public void saveUser (){
try{
FileOutputStream FOS = new FileOutputStream("User.txt", true);
ObjectOutputStream OOS = new ObjectOutputStream (FOS);
[Code] ....
The read method:
public void readUser (){
try{
FileInputStream FIS = new FileInputStream ("User.txt");
ObjectInputStream OIS = new ObjectInputStream (FIS);
for (int i=0;i<Ucount;i++){
[Code] ....
*Note: When I open the object file I could see that the information are actually there, so I think there's a problem with the read method I'm not sure what it is.
I am having trouble with a mouse click method. In short I have a hexagon grid, and every time I want to click on one particular hexagon I want the color of the hexagon to change to blue(by default the color is grey). This part works, but when I go to click on another hexagon I want the color of the previous hexagon to change back to grey while at the same time changing the color of the current hexagon clicked to blue. So in other words, I only want one hexagon blue at a time. How might I do this?
I have a hexagon class for one particular hexagon, and a hexmap class for multiple hexagons. I know I should probably be handling mouse clicks in the hexmap since it deals with the whole thing. But I cannot say something like hexagon.setColor within a mouselistener in that class(it gives me a lot of issues). Here is some of my code :
public class Hexagons()
public Hexagons(HexMap theMap, int mapRow, int mapCol, int width, int height) {
this.map = theMap;
this.row = mapRow;
this.col = mapCol;
this.width = width;
this.height = height;

I'm developing a Swing application for the first time. To test my application, I have currently hardcoded some text labels and fields in a JPanel, so that a user can enter input details for a maximum of 3 segments. But this limits the maximum number of segments to 3. However, the requirement is that when the user enters the number of segments (could be greater than 3 as well), corresponding number of input sets need to be taken.
Screenshot attached, with values entered.
Basically I want to know how I should go about taking the inputs from the user.
I have written the following code to handle multiple Client Request. Lets Assume that it takes server 300 nano seconds(ns) to process one connection request. It recieves two connection requests at time t1 and t1+200ns. Since server is busy handling request 1 at time t1+200ns. what will happen to request 2.if yes what is the max size of that buffer?Maximum number of request that a server process per unit time depends on the java code.Is there also a limit to how many request a server can recieve per unit time?
public class EchoServer
{
public static void main(String args[])
{
ServerSocket serverSocket = null;
BufferedReader readSocket = null;
PrintStream writeSocket = null;
serverSocket = new ServerSocket(9998);

Previous page can be seen even after user logs out from the JSP page.

how to resolve this?
The gist of it is to create a very basic memory game. There are 12 buttons, each associated with an icon. Every button that you click will display the icon and will stay there until clicked again. I got the bulk of it taken care of, but my issue lies with switching the icons back and forth. I can get them to display one at a time, but when I click on a new button, all the icons except the button I just clicked don't display. Essentially, only one shows up at a time.

View Replies View RelatedI am creating a mad libs type program. This section of code is for the user to be able to make their own mad lib template (that people will be able to fill out later). The normal blanks in a mad lib are for verb, noun, adjective, adverb, etc. I cam up with 13 or so of these buttons, but it would be nice that if the user wants to add a button that they think we missed, such as 'Person in the Room' or 'Silly Location'...that the user would be able to do this. I sort of pictured there being a button that says 'add button' or something like that. Is there a ways to do this with the way I've set things up?
