...ics need to be updated on screen. Assume to repaint the graphics you must call "Display.update()". The classical approach is to solve this by adding more code. At the end of each set method you write
void set...(...) {

If you have 3 set-methods, that is not a pro...
Check if table exists and if it doesn't exist, create it in SQL Server 2008
...read, and you don't have to worry about sys.objects vs. sysobjects vs. sys.all_objects
vs. sys.tables. Basic form:
IF object_id('MyTable') is not null
PRINT 'Present!'
ELSE
PRINT 'Not accounted for'

How are 3D games so efficient? [closed]
...dware.
For instance, one easy optimization you can make involves not actually trying to draw things that can't be seen. Consider a complex scene like a cityscape from Grand Theft Auto IV. The renderer isn't actually rendering all of the buildings and structures. Instead, it's rendering only what t...
Clone() vs Copy constructor- which is recommended in java [duplicate]

Beta-release days of the Java

COUNT(*) vs. COUNT(1) vs. COUNT(pk): which is better? [duplicate]
...T(field) or COUNT(*), and stick with it consistently, and if your database allows COUNT(tableHere) or COUNT(tableHere.*), use that.
In short, don't use COUNT(1) for anything. It's a one-trick pony, which rarely does what you want, and in those rare cases is equivalent to count(*)
Use count(*) fo...
What is a “cache-friendly” code?
