Yes, that's entirely feasible given the way autoboxing is guaranteed to work on small values, and is permitted to work on larger values. For example, this is guaranteed to print true: Object x = 5; Object y = 5; System.out.println(x ==... more 10/16/2015 4:20:45 PM

So, how is it that I'm able to import a class like Graphics2D, create an instance of it and use its abstract methods? Because you never create an instance of Graphics2D directly. Look at your code - you won't find this: Graphics2D... more 10/16/2015 2:53:15 AM

Sounds like you want something like: var encodedSignatures = doc.Descendants("signature") .Select(x => x.Attribute("encodedSignature").Value; Or to be more explicit about the path: var encodedSignatures =... more 10/16/2015 2:14:03 AM

The simplest approach would probably be to have a boolean field indicating whether or not that suit was red. For example: enum Suit { SPADES(false), HEARTS(true), DIAMONDS(true), CLUBS(false); private final boolean red; ... more 10/15/2015 9:24:47 PM

It sounds like you need to make two changes to fix this part - and another to fix ordering. If you want to find the count of the elements where the left join actually matched something (rather than "using" the DefaultIfEmpty call) you... more 10/15/2015 7:53:39 PM

Basically parameters in SQL only work for values - not identifiers of columns or tables. In your example, only the final parameter represents a value. If you need to be dynamic in terms of your column and table names, you'll need to build... more 10/15/2015 3:53:34 PM

You're wrong. What you're passing in isn't the array - it's a reference to the array. Arrays are reference types in Java, so the value of a1 (for example) isn't an array object - it's a reference to an array object. When you pass that... more 10/15/2015 4:30:20 AM

I suspect you can use Wait(TimeSpan.Zero) to say "try to acquire the semaphore, but abandon the attempt if you can't do so immediately." That would be my expectation, but the documentation doesn't explicitly talk about what happens if you... more 10/15/2015 4:18:12 AM

However, I tried creating multiple instances of this class in a seperate java file and only 1 instance was created. Nope, you're creating multiple instances. However, that doesn't make any difference because you don't have any... more 10/14/2015 10:54:40 PM

This is the problem: public class ArrayGrid<Sprite> implements Grid<Sprite> The way you've declared the class, Sprite is the name of a type parameter. You've made this a generic class, and I suspect you didn't mean to.... more 10/14/2015 10:33:41 PM
