what basic computer programs

A fact that violates intuitionThe computer is called "Computing" machine is because it is mainly used to calculate the invention, "calculation" of course is its expertise, in everyone's impression, the calculation must be very accurate. But in fact, even in some very basic decimal operations, the results of the calculations are imprecise.Like what: float

Thinking logic of computer programs (53), thinking 53 The previous sections introduced various specific container classes and abstract container classes. As we mentioned above, Java has a collection class that provides many common functions for container interfaces, these functions are provided in static mode. What functions are available? There are two possible

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 (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

Thinking logic of computer programs (58) and thinking 58 In the previous section, we introduced how to process files in byte streams. we mentioned that for text files, byte streams do not have the encoding concept and cannot be processed by row, which is inconvenient to use, it is more suitable to use the streaming. This section describes the streaming. First, we will briefly introduce the

Thinking logic of computer programs (68) and thinking 68 This section continues with the content of the previous section and discusses how to use wait/notify to implement more collaboration scenarios. Start at the same time At the same time, it is similar to an athlete's competition. When we hear the game start with a gun, we start at the same time. Below, we simulate this process. Here there is a main thre

Network basics of basic computer series-network protocols and basic computer networks What's the network protocol A computer with hardware, operating systems, and software already has functions that can be used. However, to realize communication between a

Thinking logic of computer programs (74) and thinking 74 This section describes a commonly used concurrent container-ConcurrentHashMap, which is a concurrent version of HashMap. Compared with HashMap, it has the following features: Concurrency Security Directly supports atomic composite operations Supports high concurrency, fully parallel read operations, and parallel write operations to a certain exten

browser setting interface, and then in the "Basic settings" option, select "re-open the last web page. In this way, no matter how many tabs are opened in Chrome, you can re-display them after restarting Chrome. Of course, do not forget to drag the Chr ome shortcut into the "Start" Column (figure 2 ).Last state of Software MemoryIn addition, you can use the "CYY super boot" software to automatically record the status of any software, folders, and webp

Part 2: Full BIOS ManualI. Award bios settings Manual Award BIOS is a type of BIOS widely used on compatible computers. However, the information in Award BIOS is in English and requires a deep understanding of relevant professional knowledge, therefore, it is difficult to set up some users. If the information is improperly set, the performance of the entire computer host will be greatly affected. The following describes the meanings and methods of se

Thinking logic of computer programs (80) and thinking 80 This section describes scheduled tasks. There are many application scenarios for scheduled tasks, such: An alarm program or task reminder. You can call a bed at a specified time or return a credit card on a specified date. The monitoring system collects system data at intervals to trigger alarms for abnormal events. Statistical System, which usual

Thinking logic of computer programs (79), thinking 79 In the previous section, we mentioned that in asynchronous task programs, a common scenario is that the main thread submits multiple asynchronous tasks and then processes the results if a task is completed, in this scenario, Java provides a convenient method for sending and distributing packets. The Completion
