   • What is the difference between an int and an Integer in Java and C#?

     Top Answer

     Answered Mar 18, 2020 · 252 votes

     In Java, the 'int' type is a primitive, whereas the 'Integer' type is an object.

     In C#, the 'int' type is the same as System.Int32 and is a value type (ie more like the java 'int'). An integer (just like any other value types) can be boxed ("wrapped") into an object.

     The differences between objects and primitives are somewhat beyond the scope of this question, but to summarize:

     Objects provide facilities for polymorphism, are passed by reference (or more accurately have references passed by value), and are allocated from the heap. Conversely, primitives are immutable types that are passed by value and are often allocated from the stack.

     Well, in Java an int is a primitive while an Integer is an Object. Meaning, if you made a new Integer:

     Integer i = new Integer(6);-

     You could call some method on i:

     String s = i.toString();//sets s the string representation of i-

     Whereas with an int:

     int i = 6;-

     You cannot call any methods on it, because it is simply a primitive. So:

     String s = i.toString();//will not work!!!-

     would produce an error, because int is not an object.

     int is one of the few primitives in Java (along with char and some others). I'm not 100% sure, but I'm thinking that the Integer object more or less just has an int property and a whole bunch of methods to interact with that property (like the toString() method for example). So Integer is a fancy way to work with an int (Just as perhaps String is a fancy way to work with a group of chars).

     I know that Java isn't C, but since I've never programmed in C this is the closest I could come to the answer.

     I'll add to the excellent answers given above, and talk about boxing and unboxing, and how this applies to Java (although C# has it too). I'll use just Java terminology because I am more au fait with that.

     As the answers mentioned, int is just a number (called the unboxed type), whereas Integer is an object (which contains the number, hence a boxed type). In Java terms, that means (apart from not being able to call methods on int), you cannot store int or other non-object types in collections (List, Map, etc.). In order to store them, you must first box them up in its corresponding boxed type.

     Java 5 onwards have something called auto-boxing and auto-unboxing which allow the boxing/unboxing to be done behind the scenes. Compare and contrast: Java 5 version:

     Deque<Integer> queue;-void add(int n) { queue.add(n);}-int remove() { return queue.remove();}-

     Java 1.4 or earlier (no generics either):

     Deque queue;-void add(int n) { queue.add(Integer.valueOf(n));}-int remove() { return ((Integer) queue.remove()).intValue();}-

     It must be noted that despite the brevity in the Java 5 version, both versions generate identical bytecode. Thus, although auto-boxing and auto-unboxing are very convenient because you write less code, these operations do happens behind the scenes, with the same runtime costs, so you still have to be aware of their existence.

     Hope this helps!

     C# is MS's ECMA standard langauge that borrows heavily from C/C++/Java (and a couple of concepts from Delphi).

     J# is essentially a version of J++ for the .NET platform. It accepts the Java-esque language that J++ did but produces .NET code rather than Java bytecodes.

   • What's the difference of the usage of volatile between C/C++ and C#/Java?

     Top Answer

     Answered Nov 12, 2013 · 20 votes

     For C#/Java, "volatile" tells the compiler that the value of a variable must never be cached as its value may change outside of the scope of the program itself. The compiler will then avoid any optimisations that may result in problems if the variable changes "outside of its control".

     In C/C++, "volatile" is needed when developing embedded systems or device drivers, where you need to read or write a memory-mapped hardware device. The contents of a particular device register could change at any time, so you need the "volatile" keyword to ensure that such accesses aren't optimised away by the compiler.

   • What is the difference between the terms non-primitive type and object type?

     Top Answer

     Answered May 23, 2017 · 5 votes

     Part of this confusion may be in that, in C#, (mostly) everything inherits from Object. To refer to an Object type in the same way, would refer to every type in the language, and essentially be useless.

     In C#, the primitive types are Boolean, Byte, Char, Double, Int16, Int32, Int64, IntPtr, SByte, Single, UInt16, UInt32, UInt64, UIntPtr. These types still inherit from object, though they are treated differently by the language. There are a few types that don't inherit from object, but they are not what you would consider primitives (ie Interfaces). The list of C# primitives can be acquired with this code, taken from here:

     var primitives = typeof(int).Assembly.GetTypes().Where(type => type.IsPrimitive).ToArray();-

     A more appropriate dichotomy, if you wanted such a thing, would be value types versus reference types. When you begin considering that difference, then you can include things such as Enum types, and other values type, like structs.
