Thinking map as a visual thinking tool, can be abstract, fragmented knowledge systematized, structured, so also by many students and office workers Love, combined with a comprehensive mind map tutorial, the brain in their own thinking to open up, so how to draw a good mind map it. If you don't know how to paint it, see how I draw it with the Quick Mind Mapping to

Childhood writing the most headache, narrative description of the text, such as good, usually encountered argumentative text on the head, I really do not know how to describe the process of my conclusion, anyway, the results seem to be right. Worse than Chinese composition is math, OK, the conclusion of the problem of proof I was introduced in the brain, so so there is a result ... The proof and calculation process is entirely from the results of the forward push ah your sister ... So, directly,

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. Different data types have different features an

Use Product thinking for training and product thinking trainingThe IT industry seems to be just one step away from entrepreneurship. Every day, the story shows the story of a certain ox leaving the big organization to start his own business. If you analyze their motivations, you will find that they are often inseparable from pain points, trial and error, fast iteration, and excellent user experience. Then a

Thinking logic of computer programs (64) and thinking 64 For file processing, we introduced the stream method, section 57 introduced the byte stream, section 58 introduced the ghost stream, and also introduced the underlying file operation method, section 60 describes random read/write files, Section 61 Describes memory ing files, Object serialization/deserialization mechanisms, and section 62 describes Jav

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

1, with "engineers" to communicate, they are committed to "faster, high-quality" delivery, they will rely on the most stable, the most perfect middleware or framework, they are more modest, like to share with the same-minded friends sharing collaboration, a wider perspective, Often choose a suitable for project development needs of the middleware or framework can be exponential speed development efficiency, save development time, can quickly bring products to customers.2, and "College School" ex

Thinking, looking for a job, Shenzhen, thinking for a job Shenzhen I am unemployed now. I am looking for a job, The age is poor, so all kinds of helplessness, There are various kinds of Enterprise mentality, If you cannot afford a salary, even if you cannot afford a salary, you can still notify you of the other side. If you do, you will be notified of the temporary termination of work, There are all ki

During my long career, I absorbed several simple general ideas and found these ideas very helpful for solving the problem. I will describe five of them now. Then I will ask you a very difficult question. It's really hard, because the question involves how to turn $2 million in startup capital into a number-2000 billion, which is a massive success. Then I will try to solve this problem through my general ideas ...... my first useful idea is: the best way to simplify the problem is to first decide

I come to the world with ignorance, to live in ignorance, to leave the world with ignorance, to be well aware of my ignorance and to be more humble. the life of a person must be accompanied by ignorance, to learn, but can not be filled with the knowledge fragments for sports capital;knowledge is endless and limitless, and only by mastering the methods and ways of doing things can we deal with the environment of illusion;the limit of technology is known as the "obvious hidden" field, so the limit

Thinking logic of computer programs (29) and thinking 29 This section describes the Character encapsulation class Character. String operations are probably the most common operations in computer programs. Java indicates that the String class is String. This section describes String in detail. The basic usage of strings is relatively simple and straightforward. Let's take a look. Basic usage You can use cons

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 basic concepts of

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 (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

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 types: For the first type, operations can be

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 are not accurate. For example: float f = 0.1f*

according to this conversation, the output of this four-digit number, if not, outputs "not sure".Sample Input64815 2 15716 1 07842 1 04901 0 08585 3 38555 3 224815 0 02999 3 30Sample Output3585Not surethe topic is clearly described. The first idea is to infer, as he says, what the number is based on what is known, so that it falls into deep thinking because it does not know how to infer it. Correct idea: Enumerate the numbers between the 1000~10000 t

Rigid thinking in software development and rigid thinking in software development In the J2EE field, SSH/SSI is a good thing and a result of the painstaking efforts of masters. But he is also a bad thing. On the good side, I believe you don't have to say much about it. A large number of design patterns are used to greatly reduce the entry barrier for programmers, standardize enterprise application developm

First, understand the nature of use cases use cases are system thinking A system is a closed, interconnected, interconnected set of substances that affect each other. The so-called system thinking is to consider the interaction of the things in the system, inductive and abstract operating rules within the system. Software does not exist in isolation, at design time we must put the software in its system

Thinking logic of computer programs (19), thinking Logic Restrictions on Data Types Previously, we have been saying that programs mainly involve data and data operations. To facilitate data operations, the advanced language introduces the concept of data types. Java defines eight basic data types, A class is equivalent to a custom data type. It can represent and operate various things or objects through the
