Simply put that's not possible.
Hmm... interesting. I thought that would get rid of the error, but doing some testing it seems that's not the case. Yes, it is a runtime check but I seem to remember there being some "code structure"...
You can use instanceof to check the type.
if(o instanceof ArrayList<String>)
{
ArrayList<String> l = (ArrayList<String>) o;
}
Presumably the vehicle.Company can't be both G and F? It makes more sense to use an if-elseif type control flow, or even just an if-else if there can't be any other values for Company. This makes...
So my development process actually starts with comments. I begin by describing what it is I need to do and roughly how it should get done. Filling in the actual code comes second.
Adding extra...
It seems like you are trying to provide several distinct actions in a single method. Checking where a unit can move should probably be a distinct method from actually moving the unit. Both of these...
It sounds like you are running into a hardware limitation of your keyboard, not a software one. There is no possible software fix, the only option is to use a different keyboard.

Check the order of your commands. Java executes top-down in a block.
curly braces in Java are used to denote blocks. Semi-colons are used to denote the end of a single statement. A for loop has syntax like this:
for(initialize; condition; increment)
...
Yes, those are operators. They are not specific to for loops (as PhHein said).
The two combined form a ternary operator (i.e. 3 parameters).
a ? b : c
How to read this:
If a is true,...
When in doubt, run your code through a dissassembler. The Oracle JDK includes a javap tool which allows you to decompile the output.
I copied your code into test.java (default compiler options,...
An anonymous class is just like a regular class, except it has no name. That means you can never refer to the type.
new BaseType(base_parameters){
// pretty much everything you can put into...
You are creating an object of an anonymous class, which extends/implements javax.mail.Authenticator (depends on if javax.mail.Authenticator is a class or an interface).
I have a few posts about implementing the sieve of Eratosthenes efficiently:
Optimizing the Sieve of Eratosthenes
One problem using the raw sieving technique is that the sieve asks the question...
@javaiscool Please don't spoonfeed answers. Please read: The problem with Spoon Feeding
In Java 8 there are plans to implement Lambda expressions/Closures. I haven't read through the details on how these features will work in Java specifically, but in other languages with closures these...
There are many different ways to implement a checksum. See: Wikipedia: List of Checksums.
The output I get is exactly 4. What is the exact code you're using? Perhaps there are computations which result either parameter to "about 2", which would throw the result off.
Yes, don't store the result into s and just use it directly. I wouldn't suggest doing this in practice, though as your line will become way too long and unreadable.
It's silly to try and write as few lines as possible because Java code doesn't really care about the concept of "lines": you can put everything into one line and barring line comments, have it work...
Declare your classes as public.
We can't read your mind or see what is on your computer screen. You have to post enough information here for us to be able to help you. What code you you have so far, what is it doing (exactly), and...
What is the error message? Please copy/paste it here in its entirety.
Static methods aren't polymorphic. Which static method is invoked is determined by: 1. The type of the variable being used (note that the variable type is not necessarily the same as the type of the...
The reasoning for 1 is a bit convoluted. It is O(n) because you are running it half the time: O(n/2). But big-O drops the constant factors, so we're left with O(n)
#5 is not O(n^2). O(n^3) isn't a...
