I was writing a (seemingly) straight-forward SQL snippet that drops a column after it makes sure the column exists.
The problem: if the column does NOT exist, the code inside the IF clause complains that it can't find the column! Well, doh , that's why...

It, and sees that a non-existing column gets referenced somewhere (even if that piece of code will never.

Hi everyone,
I'm trying to set the main class in netbeans to be the main class it was in the last environment it was in, however the program insists it can't find the main class itself and when I set it as the name of the main class in project properties...

The way applets work in Netbeans ....
So you probably have an option to import the project as an applet-project, not as standalone-java-app, in Netbeans .
Do you really speak about an applet? Applets have no main-class (they can, but they do not have to) .

In the 1940's a corporate executive made about 12-15 times what a plumber or assembly line worker earned. By the 70's that figure had grown to about 50 times. In 2010 an average CEO made about 550 times what an ordinary worker earned plus company provided...

Why does $('tr:even').addClass('alt'); select from the 1st row and $('tr:nth-child(even)').addClass('alt'); selects from the 2nd row ?

Got it! :odd and :even....
Maybe the selector looks at the index and nth-child(even) looks at the length? Seems like an oversight.
It's because :even gets even elements using 0-based indexing and :nth-child() uses 1-based indexing.

Or 2 for producing either odd or even number:
Odd
CREATE SEQUENCE odd_seq INCREMENT BY 2 START WITH 1;
Even
CREATE SEQUENCE even_seq INCREMENT BY 2 START WITH 2;.

I have to create a method which has an ArrayList; I need to remove even numbers from this ArrayList. I have written code for that but there is a logical error which I couldn't identify.
Here is my code:
static void sortList(){ List <Integer> number...

Like this:
for (int i=0;i<....
Try adding a "i--;" line inside your "if (even==0)" block.
I would are modifying the list while you are traversing it .
In your implementation 32 is not removed as it comes directly after another even number.

What is the fastest way to find if a number is even or odd?

Bool is_....
Zero would be counted as even though.
If it's an integer, probably by just checking the least significant bit .
Int i=5; if ( i%2 == 0 ) { // Even } else { // Odd }
if (x & 1) is true then it's odd, otherwise it's even.

It has no literal representation so you can't even write Missing = Missing.

In C I need to scale a uint8_t from 0 - 255 to 0 - 31
What is the best way to do this evenly?

Answer Snippets (Read the full thread at stackoverflow):
You can use some simple multiplication and division:
uint8_t scaled = (uint8_t)(((uint32_t)original... .
If you're trying to scale from 8 bits to 5 bits, you can do a 3 bit shift;
uint8_t scaled = (uint8_t)(original >> 3);
This drops the lower 3 bits .

How do we print a number that's greater than 2^32-1 with int and float? (is it even possible?)
Answer Snippets (Read the full thread at stackoverflow):
Given this data structure, how do we print it? With BigInteger_... .
How does your variable contain a number that is greater than 2^32 - 1? Short answer: It'll probably be a specific data-structure and assorted functions (oh, a class?) that deal with this .
