View Replies View RelatedDealing With Spaces During Input String Conversion?
Oct 5, 2014I am working on a small brain teaser project where I am taking a string input from a Scanner, and turning into ascii. The problem comes into play when the string has a space in it, so if the question is what's your name? and you say Michael Jackson, Michael gets converted then Jackson becomes the answer to the next question, rather then the second portion of the current string.
This is an older version of what I'm doing currently, but it had the same basic problem with spaces.I will say I did my current version entirely different.
nner user_input = new Scanner (System.in);
//Creates a string
String favoriteFlick;
System.out.println("Enter the title of your favorite film?");
favoriteFlick = user_input.next();

PopupMenu And JEditorPane String To Image Conversion
Jan 15, 2015I am working on a simple online chat program. I have build the server services and generally everything works smoothly.Now for the input area i use a JEditorPane as like the output message area. The reason of choosing JEditorPane is because i want to apply some CSS on future...

Download Image (stored As Blob) From Database To Client Machine?
Jul 2, 2014We have web based application (Oracle DB, Weblogic middle tier) and a applet based application running on the browser.
We have a requirement to Load images from the database (stored as blob) to the client browser and the users can do the lookup on images when needed.
We need this to perform well, so there is no delay for the user experience. We have 2 options:
1. Load the images from the database to the Application Server and keep it. When the client request from the browser comes, download it from the application server.
2. Load the images (asynchronosly) when the user logs into the application and download them to the Client machine? Is this possible? Especially give that it is stored in the database as binary objects?
And then load for the user from the client box itself, upon request.
If 2nd option is possible, which once is recommended?
