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

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 (73) and thinking 73 In this section and the following sections, we will discuss the container classes in Java and package. This section describes two simple classes, CopyOnWriteArrayList and CopyOnWriteArraySet, and discusses their usage and implementation principles. Their usage is relatively simple. What we need to understand is their implementation mechanism: Copy-On-

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 (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

Unnecessary programs in Windows How to prohibit the operation, the computer after a period of time will appear some unnecessary procedures, will affect the speed of our computer, if you do not need to prohibit these programs to start on it. But how to forbid it? The following three networks tell you the specific steps.

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

This section 1. Some traditional methods2. Generate a QR code image from the program code.3. Scan the generated QR code on your mobile phone and convert it to a py script.Preface Writing scripts on the most mobile phone is a hard task. Although SL4A provides us with the API Quick insertion function, in addition, the elegant Python saves us the trouble of entering semicolons and parentheses, but it does not have intelligent awareness, no keyword completion, narrow buttons, and difficult to enter

The function of an ordered pair is to store two values and then provide again as neededPAIR = x {-y {-f {f[x][y]}}}left = p {p[-x{, y {x}}]}right = p {p[-x{y {y}}]}When I read the first time, I did not understand these lines of Ruby code, and I wrote a JavaScriptPAIR = function (x) {return function (Y) {return function (f) {return F (x) (Y)}}}left = function (p) {return P (function (x) {return function (y) {return x}})}right = function (p) {return P (function (x) {return function (y) {return y}}

Thinking logic of computer programs (51) and thinking 51 The previous section describes EnumMap. This section also describes the implementation class EnumSet for the Set interface of the enumeration type. Similar to EnumMap, there is a special implementation class for enumeration types, mainly because it can implement the Set interface very efficiently. The implementation class HashSet/TreeSet of the Set in

Microsoft's secret program, originally codenamed Milan five years ago, finally came out on Monday (5/29) and was named "Surface computer. In the future, this big touch computer, which looks like a coffee table, will be expected to appear in restaurants, restaurants, retail outlets, or casinos. Microsoft CEO Steve Ballmer announced the release of

Thinking logic of computer programs (5), thinking Logic Intuitive fact violations The reason why a computer is called a "computing" machine is because it was invented mainly for computing. "computing" is of course its specialty. In everyone's impression, computing must be very accurate. But in fact, even in some basic decimal operations, the calculation results a

corresponds to Java.In 32-bit format, 1 bits represent the symbol, 23 bits represent the mantissa, and 8 bits represent the exponent. In 64-bit format, 1 bits represent the symbol, 52 bits represent the mantissa, and 11 bits represent the exponent.In the two formats, in addition to the normal number, the standard also specifies that some special binary forms represent some special values, such as negative infinity, positive infinity, 0,nan (non-numeric, such as 0 times infinity).The IEEE 754 st

Thinking logic of computer programs (67) and thinking 67 The previous section introduced the problem of competing multiple threads to access the same resource and the solution synchronized. we mentioned that in addition to competition among multiple threads, mutual collaboration is often required, this section describes the basic mechanism of multi-thread collaboration in Java. What scenarios need collabora

Later, if the program assigns a value to *p, it may actually be modifying the data in another function stack frame, potentially with disastrous and confusing consequences.9.
