1. Use Matlab as a closed polygon drawing Instead of finding a function that directly draws a polygon, you can only save the coordinates of each point in an array, connect a point to its adjacent point, and attach the last point to the first point. The following is an example of the. m File: Copy Code code as follows: Clear CLC A=[0 2 4 6 8 10 12 14;0 2 1 4 6 6 5 7]; % the point coordinates to be connected x;y [N,m]=size (a);

Transferred from https://my.oschina.net/fhd/blog/289945 Examples are as follows: Package test; public class Gen Package test; public class Gendemo {public static void main (string[] args) {* * in Java7 and later versions, the generic type can be omitted from the constructor, as in the following In this way, * only a pair of angle brackets Let's analyze some of the code in the example above. First, notice how this line of code declares the gener

If a class has 3 methods, set a breakpoint in front of the 3 methods, a total of 3 breakpoints, and then enter Debug debugging,Always press F6 (step over) he will go directly into the method and not need you to press F5 (step Into)Or you just set a breakpoint in the first method, then you need to press F5 (Step into) to enter the method when debugging.Package args parameter problem;/* * Study questions 1: Look at the program to write the results, and then analyze why it looks like this. and draw

The socket is also called a socket, and the application usually makes a request to the network through a "socket" or answers a network request.Java has simplified the programming interface for sockets. Java provides serversocket to support it. In fact, when creating an instance object of the class and providing a port resource, a fixed location can be set up for other computers to access, such as: ServerSocket server=new serversocket (6789);A little n

amount of space memory. When the request arrives, the buffer pool assigns an idle thread to the request, runs the request into the thread, and processes it. When a predesigned thread is running, a prefab thread is not enough, the thread pool can create a certain number of new threads to handle more requests. When the system compares space, you can also remove a part of the thread that is inactive.The advantage of this is that, on the one hand, the system resource overhead of frequently creating
