In this chapter we will discuss the hash collision.1. What is a hash collision?Is the hashcode of the two object's key is the same, how to get his value at this time?The answer is to traverse the entry linked list above the table at that position through equals.2. ExampleA normal example:Package Com.ray.ch14;import Java.util.hashmap;public class Test {public static void main (string[] args) {hashmapOutput:Person Id:1,hashcode () invoked,hashcode:44316
structure-sized memory spacemarshal.copy (bytes, 0,structptr,size); // obj= marshal.ptrtostructure (Structptr,type); marshal.freehglobal (STRUCTPTR); Returnobj; } } } 3. Last look at the client//1. Create a nested section wordm_s=NewSockets (AddressFamily.InterNetwork, Sockettype.dgram, PROTOCOLTYPE.UDP);//2. Fill in the server IPIPAddress IP=Ipaddress.parse ("127.0.0.1");IPEndPoint Ipe=NewIPEndPoint (IP,4321);//Send this user information to the serverCp2pmessage msg=NewCp2pmessage ();
MEF is easy to get started with, but it strives to be easy to understand (4 ).
In the previous article, we can obtain various FileHandler instances and corresponding metadata. In this article, we create a slightly complete file manager.
1. Modify the IFileHandler interface and input the file name.
namespace IPart{ public interface IFileHandler { void Process(string fileName); }}
