useful in situations where you do not need to instantiate a class."2" Construction code blockIn the class:Format: {Construct code block execution statement}Function: initializes all objects.Note what time: 1. Every time you create an object, he will execute it.2. Construction code is faster than constructor execution.3. The difference between building blocks and constructors is that building blocks of code is a unified initialization of all objects, and constructors are initialized to the corre

, retrieval, storage and management, and the design and implementation of the basic methods of geospatial information analysis. This paper introduces the basic of GIS algorithm, coordinate transformation algorithm, data transformation and organization algorithm, space measure algorithm, index algorithm, interpolation algorithm and so on, which basically covers some fundamental GIS algorithms that we use daily. Of course, it would be better to pick up our calculus and linear algebra again before

contain 1. Suppose that an integer is stored in one byte (8 bits), and if A is an unsigned integer variable, then when the a=64 is shifted to the left one when the overflow is 0, and the left 2 bits, the overflow high position contains 1.6. Right shift operator (>>)The right-shift operator is used to move the bits of a number to the right of a number of bits, the number of bits moved is specified by the right operand (the right operand must be non-negative ), the low end of the right side is di

. Subclasses have the responsibility to extend the superclass, rather than the responsibility of displacing (Override) off or unregistering (nullify) out.4. Inheritance can only be used if it is taxonomic and not inherited from a specific class.The difference between an interface and an abstract class:1. Abstract classes can provide implementations of certain methods. If you add a new, concrete method to an abstract class, all of the subclasses get this method in a single swoop. Interface does n

working on hardware need to master the assembly. I agree that many people say that the assembly is useless and should now learn a high-level programming language. I also said at the beginning of this article that the current learning assembly is just to be able to read the disassembly code in reverse work, or to write shellcode in the exploit technology, or some experts like to embed the assembly code in their own program, to improve the efficiency of the program ... This is the current compila
