Is there a way to both check a macro is defined and it equals a certain value at the same time
as far as I can tell, there is no preprocessor option to throw errors/warnings if a macro is not defined when used inside a #if statement. It can't be an error because the C standard specifies that behavior is legal. From section 6.10.1/3 of ISO C99 standard: After all replacements due to macro expansion and the defined unary operator have been performed, all remaining identifiers are replaced with the pp-number 0.... As Jim Balter notes in the comment below, though, some compilers (such as gcc) can issue warnings about it. However, since the behavior of substituting 0 for unrecognized preprocessor tokens is legal (and in many cases desirable), I'd expect that enabling such warnings in practice would generate a significant amount of noise. There's no way to do exactly wha

MSDN code example: Why does it check null before calling static Object.Equals?
Your approach would end up invoking the virtual Equals(Object) method, because that's what Object.Equals does. The way that's given here only uses Object.Equals when at least one of the values is null, in order to return true if they're both null and false otherwise - that path will never call back into your Equals implementations. If both values are non-null, the MSDN approach will make a non-virtual call straight to bool Equals(Person) - which avoids not only a virtual method indirection, but also another type check which is redundant when we already know that if the references are non-null, they're both Person references. I think the example is unfortunate in its mixture of using fields and properties, mind you - and I'd definitely write this: if (this.uniqueSsn == other.SSN) retu

Java .equals() instanceof subclass? Why not call superclass equals instead of making it final?
Your attempt at solving the problem is not correct. Suppose you have 2 subclasss SpecialPerson and BizarrePerson. With this implementation, BizarrePerson instances could be equal to SpecialPerson instances. You generally don't want that.

When overriding Object.Equals, is it appropriate to use the passed in object's Equals(MyType)?
No, this is a bad idea. While infinite recursion does not happen with this code, it is a constant threat when you have some instances of Equals() delegating to others. (If you use this approach then I'd strongly suggest writing many unit tests to make sure that Equals() does what you expect in all cases.) Note that when a.Equals((object)b) returns true, a.GetHashCode() == b.GetHashCode() must also be true. If you cannot ensure that new WholeNumber(2) and new Fraction(2, 4) have the same hash code, then they should not compare as equal by Equals(object). The practice I have adopted is that the Equals(object) override only returns true if the argument's type is or derives from the type where the override is declared -- in this case, obj is WholeNumber. If this is true but obj.GetType()

Using Prolog: Given a list check if the first element of the list equals the last element
Here's an easy one: fela(L) :- first(E, L), last(E, L). Stare at that for a minute and let it really sink in. Actually, it would be right, but your last/2 isn't, simply traversing the list with no base case that will ever succeed. A correct last/2 would look like this: last(L, [L]). last(E, [_|L]) :- last(E, L). I see a lot of confused ideas in your case analysis. For one thing, in Prolog, you don't explicitly return true and false. You simply match what you match and the rest is failure. When dealing with lists, you automatically inherit the base case of the empty list and the inductive case of an element and the remainder of the list. This isn't sufficient to implement fela/1 from scratch because you have no way of remembering what your first element was. So if you want to build i

What Is The Difference Between .equals() and ==?
You need to implement your own .equals() method for the Vertex class. By default, you are using the Object.equals method. From the docs, this is what it does: The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true). You can do something like this: @Override public boolean equals(Object obj) { if (obj == null) return false; if (obj.getClass() != getClass()) return false; Vertex other = (Vertex)obj; return (this.id == other.id); }

How do I use .equals properly for this?
One problem is that you do not supply the source code for Sprite, but perhaps it looks like the code here? Given the code there, there is no neat solution to your problem with the class as it is. So, how I would approach solving this problem is to add to each sprite a resource ID: private Sprite createSprite(int resource) { Bitmap bmp = BitmapFactory.decodeResource(getResources(), resource); return new Sprite(this, bmp, resource); } Note that I add the extra resource parameter to the constructor. Furthermore, I would add to the Sprite class a method int Sprite.getResource(), so your collision detection code becomes: if (sprite.isCollition(x, y)) { if (sprite.getResource() == R.drawable.bad1) score = score + 5; else if (sprite.getResource() == R.drawable.bad2)

c# enum equals() vs ==
If the compile-time type of enumInstance is the enum type, you're fine with ==. If the compile-time type of enumInstance is Enum, ValueType or Object, you need to use Equals. (You'll get a compile-time error if you try to use == in that case.) Note that your enum currently violates .NET naming conventions - it would normally be MyEnum.Value.

Should be ok as long as you are doing a NPE check before calling equals() inside compareTo().

Java Object.equals
Because, of Polymorphism. At runtime, the actual type of object determines which implementation of an instance method should execute. Since, HashSet inherits an overridden implementation from AbstractSet it's used for comparison instead of Object.equals() And, the JavaDocs for AbstractSet#equals() state Returns true if the given object is also a set, the two sets have the same size, and every member of the given set is contained in this set. Hence, your equality test prints true. So, the type of reference (Object, in your case) has little bearing on which version of equals() is invoked at runtime. It entirely depends on the type of object your reference is pointing to.

Using a cached hashCode() value in equals()
Your optimization would require more work on String objects that are actually equal to each other, as you'd still have to iterate them to ensure they were equal. The contract requires that equals objects produce the same hashcode. The reverse is not true, in that, objects which produce the same hashcode are not necessarily equal (a hash collision).

Hibernate equals method
Liferay does something similar to the below solution. I hope it helps. This solution would require an additional column in your table and a field in your entity which would hold a unique "counter". This the counter that would make your entities unique. There would be a new table, say "ENTITY_COUNTER" table, that would have two columns - 1. your entity name and 2. the highest "possible" counter given out. You would need to create a singleton which would hand out these unique counters (think tokens) to your entities when they are created. The counter would be incremented by 1 every time an entity takes a token. Your singleton would not go to the database every time to update the highest token. It would update the database every time it has given out say a 1000 unique tokens. The singlet

Floor(X) modulo X equals X?
Modulo means we divide and take the remainder (just like in 3rd grade for me). So ... 10 % 9 is 1. And 10 % 10 is 0 And 10.5 % 10.5 is 0. (Perhaps you could get rounding issues if you had x = ...calculate 10.5.. and then x % x where you would get a number just below 10.5 or just larger than 0.) So, for all integers, Floor(x) % x is 0. For a non-integer, it works differently. Floor(10.5) => 10 and 10 % 10.5 is 10. So barring the effect of rounding errors in the floating point, Floor(x) % x is either 0 (for integers) or Floor(x) for non-integers. More Perhaps you could tell if it passed a grid line by comparing the before and after positions: if (Math.Floor(xAfterMoving / gridSize) != Math.floor(xBeforeMoving / gridSize)) { fireXGridCrossingEvent(); }

With Integer class, the equals() method is already overridden and which checks for the value. Also, whenever you are overriding equals(), override hashcode() also public class A { private int number; A(int number){ this.number = number; } public int getNumber() { return number; } public void setNumber(int number) { this.number = number; } @Override public int hashCode() { final int prime = 31; int result = 1; result = prime * result + number; return result; } @Override

Perl not of a string equals to?
The ! is the unary logical negation operator. False strings are "" and "0". If such a string is negated logically, this evaluates to 1. All other strings are true-ish. The negation of these is "" (the empty string) or numerically 0. Other false values are undef and the number 0. Therefore, the ok ($pass, $test) will pass if $message is undefined, the empty string, or zero.

Double equals in for loop?
The loop executes only if the condition evaluates to true. At the first iteration, $z == $cnt is false, so the loop never executes. A common loop strategy is to use a sentinel value: $cnt = 5; $stop = $cnt + 1; for ($z = 0; $z != $stop; $z++) { . . . } Note that the comparison is negative (!= or !==). Using a sentinel is usually unnecessary for numerical loop variables (I wouldn't recommend it for your posted code), but is useful for other situations (e.g., when $stop represents null, an illegal value, etc.). It's particularly helpful when the loop variable changes in a pattern that is not easy to characterize succinctly.

equals() and == for the class object
They are a bit different. equals() method is present in the java.lang.Object class and it is expected to check for the equivalence of the state of objects. That means, the contents of the objects. Whereas the == operator is expected to check the actual object instances are same or not. Another difference is that the equals() method can be overridden. That way, you can change it to act like you desire.
