Auto Updating JTable From Database
Feb 10, 2015I'm doing an application which needs a JTable with data from an existing database. I need the table to periodically (I plan to use a Timer) reflect the changes made to the DB (inserting new rows, deleting or updating existing rows) without making the dirty approach of clearing the whole JTable and refilling it again, which is not nice. I need to just add/modify/delete the needed rows, not the whole table.
View Replies View RelatedAuto Click And Auto Populate Data
Sep 26, 2014I am working on a project named as "Auto Click and Populate". This is link is like online feedback form / surveys which we program. I have a link with me which is mentioned below and there will be a counter box which will hit the link that much number of times.
Inputs:
-A text box having this link.
-A numeric box having counter number i.e. the number of times the link should be processed.
-A button named as process which will INITIATE the process.
Now say if I input 10 into the numeric box; the attached file contain link should be processed 10 times and the question which is coming on the link should be answered randomly out of the options which are present. For ex: When you will hit a link; the first question will be gender in that 3 options are present "Male", "Female" and "Prefer not to answer"; either of 1 out of 3 should be punched automatically and proceed automatically ahead. The punch(es) will be stored in database which is maintained at my end.I have done research and till now found the code for auto click only and not for auto process.

Servlets :: Generate M By N Multiplication Table Based On User Input
May 8, 2014I have a basic html form with one user input text box labeled "Enter a number" and a submit button labeled "Create a multiplication table". This is the working with a servlet to display an html formatted multiplication table. Everything else is working fine just the formatting is off; I can't seem to get the top row and far left column to number properly. It should look like this with the top row of numbers beginning with a blank cell and then numbering 1 thru n (depending on what the user selects. The first column should be the same, a blank cell and then 1 thru n. Then the multiplication table should be in the rows/columns of the table. Picture this:
I can't get mine to start with a blank cell in the top left-hand corner, instead it has 1 in that cell and the table starts calculating with 2x2.

Java Database - Inserting Value By User
Apr 25, 2014So I am working on a DB homework assignment and I am confused in how to implement a users input into the DB; I have to enter some values into a Table that is filled out by a user. It is a basic program, no GUI needed at this point.

Building A Registration System
Jan 18, 2015I'm assigned along with two others to make this program for a project.
We need to store data to the program by adding them such as user_id among the 5 criterias that are needed. Lets say I want a new user, I need the program to give me that option and then I would type in the user id and the program would store that data information
As far as I'm aware, boolean, screentokenizer and scanner is involved in the making of this program.

BufferedImage Auto Rotate JPG
Apr 11, 2015I need my Java program (I'm working in Eclipse if it matters) to detect if an image is a portrait or a landscape, but since i am directly downloading them from my camera they only have it written somewhere in metadata, the image width and height is the same for landscape and portrait. I have the rotation code and the rest of the program working, but I need to somehow get a variable (for example integer one) to tell me if it is a portrait or a landscape image. I tried getting to the metadata but my Eclipse decided that import com.drew.metadata.Metadata; cannot be resolved.
BufferedImage image = ImageIO.read(new File(imagePath, imageName)); and after I get the variable "orientation" it looks like this
int orientation = ???;
BufferedImage newImage = oldImage;
if (orientation>1){
newImage = rotate(oldImage);
}
How To Avoid Keyboard Auto-repeat
Oct 8, 2014I wanted to make a small program to move a small rectangle by pressing the WASD keys. The program works, except that when I hold a key to move the rectangle, after a second, auto-repeat starts up, and the rectangle motion accelerates. I want to prevent automatic repeat to activate, so that the rectangle moves at a constant speed when I hold a key and stops when I released. Here is the ButtonMotion classe :
