Manual modeWe first create manually, and then the program implementation, the principle is the same, but the program is relatively handsome, of course, but also relatively high-end (in some applications).Mouse Right click HKEY_CLASSES_ROOT, pop-up menu, choose New--Item1. Suffix keyCreate: Then create a key, we give it a name, here is the suffix name:. Opo.Write value: Select the key, and then double-click (default) in the right interface, and we enter the name of the processing key

Thinking logic of computer programs (26) and thinking 26 Packaging Java has eight basic types, each of which has a corresponding packaging class. What is the packaging class? It is a class that contains an instance variable and stores the value of the corresponding basic type. This class generally has some static methods, static variables, and instance methods to facilitate data operations. In Java, the bas

Thinking logic of computer programs (23) and thinking 23 In the previous series, we introduced the basic data types, classes, and interfaces used to represent and operate data in Java. This section discusses enumeration types in Java. Enumeration is a special type of data. Its values are limited and can be enumerated. For example, a year has four seasons and a week has seven days, although classes can also

different for different contracts.Novice programmers often use meaningless names like A,b,c,hehe,haha to give variables a meaningful name!By declaring variables, each variable giving a data type and a meaningful name, we tell the computer what data we want to manipulate.With the data, how to manipulate the data?-long serial, not to be continued, please pay attention. Author of the public number ( Lao Ma sa

enumeration types are more concise, secure, and convenient.We've mentioned anomalies before, but we haven't discussed them in depth, let's discuss them in the next section.----------------To be continued, check out the latest articles, please pay attention to the public number "old Horse Programming" (Scan the QR code below), from the introduction to advanced, in layman's words, Lao Ma and you explore the nature of Java programming and computer techn

Thinking logic of computer programs (94) and thinking 94 The previous two sections discussed functional data processing in Java 8, which is an enhancement to the container class introduced in sections 38 to 55, it can combine multiple operations on the set data in a pipeline. This section continues to discuss the new features of Java 8, mainly a new class CompletableFuture, which is an enhancement to concur

previous introduction is the flow, in addition to the flow, there are other ways of operation, such as random access and memory-mapped files, why do you need these methods? What are their characteristics? For what occasion? Let's move on to the next exploration.----------------To be continued, check out the latest articles, please pay attention to the public number "old Horse Programming" (Scan the QR code below), from the introduction to advanced, in layman's words, Lao Ma and you explore the

Thinking logic of computer programs (91) and thinking 91 In the previous sections, we have discussed Java 7. From this section, we will discuss some features of Java 8, including: Passing behavior code-Lambda expressions Function-based data processing-stream Combined asynchronous programming-CompletableFuture New Date and Time API In this section, we will first discuss Lambda expressions. What is it?

file.Continuous read-only code snippets and read-write data segments, which makes it easy for the loader to page and initialize contiguous areas.At load time, the read-only code snippet and the writable data segment corresponding to the page table are initialized to a page that is not cached (involving the operating system and the principle of composition), pointing to somewhere in the destination file on disk. So, during the program loading process, there is no real load of code and data from

Thinking logic of computer programs (1), thinking LogicWhat is the program? A computer is a machine that consists of CPU, memory, hard disk, and input/output devices. Operating systems run on the computer, such as Windows or Linux, and various applications, such as Word and QQ, run on the operating system. The operatin

Thinking logic of computer programs (90) and thinking 90 Section 88 introduces the regular expression syntax. The previous section describes Java APIs related to regular expressions. This section discusses and analyzes some common regular expressions, including: Zip code Phone number, including mobile phone number and fixed phone number Date and Time ID card IP address URL Email Address Chinese cha

Thinking logic of computer programs (87) and thinking 87 In the previous section, we discussed dynamic proxies. in the previous sections, we mentioned ClassLoader for many times. This section will discuss in detail the class loading mechanism and ClassLoader in Java. ClassLoader is the Class for loading other classes. It is responsible for loading bytecode files to the memory and creating Class objects. Lik

Thinking logic of computer programs (14), thinking Logic It is said that Tao shengyi has a second, second, and third life. If binary representation and operation are regarded as one, the basic data type is regarded as two, and the basic data type is regarded as three, then, the combination of classes and the inheritance introduced in the next section make the three born things. In the previous section, we i

Thinking logic of computer programs (13), thinking Logic Class In the previous section, we introduced the basic principles of function calling. In this section and the next sections, we will explore the world of classes. Programs mainly involve data and operations on data. To facilitate understanding and operation, advanced languages use the data type concept. Di

Thinking logic of computer programs (59) and thinking 59 The previous two sections show you how to read and write file content through a stream. This section describes operations on file metadata and directories. File and directory operations are ultimately related to the operating system and file system. The implementations of different systems are different, but Java. io. the File class provides a unified

Thinking logic of computer programs (78) and thinking 78 In the previous section, we initially discussed the task execution service in Java and package. In reality, the main implementation mechanism of the task execution service is the thread pool. In this section, we will discuss the thread pool. Basic Concepts A thread pool, as its name implies, is a thread pool. There are several threads in it. They are

Thinking logic of computer programs (39) and thinking 39 In the previous section, we introduced the ArrayList. the random access efficiency of ArrayList is very high, but the insertion and deletion performance is relatively low. We mentioned that the List interface's parallel List is also implemented, its features are almost the opposite of that of ArrayList. This section describes the feature list in detai
