There is a section explaining the value types and reference types well. Excerpt from a book, as follows:Before analyzing the value types and reference types in C #, let's say two examples to make the concept of abstraction concrete.Suppose you are reading a book, and your friend wants to see the book in your hand at th

JNI/NDK Development Guide (iii) -- ing between JNI data types and Java data types, ndkjni Reprinted please indicate the source: http://blog.csdn.net/xyang81/article/details/42047899 When we call a Java native method, how does the parameter in the method pass to the local function in C/C ++? How are the parameters in the Java method converted from those in the C/C ++ function? I guess you should have relat

Why to translateOne is in order to feel the best foreign technology community well-known bloggers high-quality articles, and secondly is to review the right. NET Technology Foundation supplements achieves the restudying effect, finally also is in order to exercise own English reading and writing ability. Because it is the first time to translate English article (Ah, forgive me this dish than, weak explosion!) , so there will certainly be a lot of problems (some of the sentence understanding is n

The CLR supports two types: reference types and value types. Reference types are always allocated from the managed heap. The new operator in C # returns the memory address of the object. Note Points for referencing objects: 1. Memory allocated from the managed heap 2, the heap on the allocation of objects, there

The basic types of Java are Byte, short (not used), int, long, float (to be used sparingly), Double,char, Boolean (either false, or True)For the Boolean example, the following:The value of int a=3;if (A>2)//a>2 is true and cannot be written like this if (1) System.out.println ("Awesome"); ElseSystem.out.println ("dumb"); The following if most direct if ( true) System.out.println ("Awesome"); ElseSystem.out.println ("dumb");An interesting computational
