In the previous article we learned about the factory model, introducing simple factory models, factory methods, and abstract factory models. This article introduces the builder pattern and prototype pattern in the design pattern that belong to the creation pattern.Introduction to Builders ' models
Builder mode is the creation mode. The builder mode uses multiple simple objects to construct a complex object step-by-step. This type of design pattern belongs to the Create pattern, w
uid card is a card without 0-sector protection, so you can modify the uid you want at will, so that we can clone a card with the same uid. (However, do not break the 00 sector. During the previous test, the 00 sector cannot be read due to unknown reasons ).4) sniffing attack
PM3 is used here to sniff data and attack data during card-to-machine data exchange, using the XOR key calculation tool, you can calculate the key of a sector (which means you ca

How to use Youku ido, this is very simple we look at two tutorials on Youku Ido.
1, Youku Ido how to make MV video with photos
First we turn on the Youku Ido video tool, First click = = "Picture mv" = "Add Picture".
On the local computer---Find the pictures you need to make MV video, you can choose more than one.
Upload if the picture order is messy, you can use the mouse to drag pictures to move the position.
The first step: first click on the "theme" to choose their favorite s

Throwable.getstacktrace () is also a native method. The principle is also based on StackFrame(run stack) to get information about the corresponding class. Returns a stacktraceelement[].The Stacktraceelement class is inside the JDK1.4 's Java.lang bag. It contains a wealth of information and is ideal for debug.The Stacktraceelement class has the following methods:GetFileName (), Getlinenumber (), GetClassName (), Getmethodname ().18

oscillator as the 32KHz clock source. The osc32k bit of the Clkconcmd register can be written at any time. The oscillator will not work before the active system clock source. When the system clock changes from 16MHz to 32MHz Crystal oscillator (Clkconcmd.osc from 1 to 0) once the 32KHz RC oscillator is selected its checksum is started and executed. During calibration, a crossover amount of the 32MHz crystal oscillator is used. The result of the 32KHzRCOSC oscillator calibration is that it will

Each specific object has its own unique State. For example, the apple skin is red and the pear skin is green. Apple has less moisture and more pears. Therefore, Apple and pear are fruit, but they are independent individuals in the fruit category. These individuals are unique objects, so the relationship between objects and classes becomes clear:Each object belongs to a specific class that defines fe
multiple variables of the same type. However an array itself is an object in the heap. We will learn how to declare, construct and initialize in upcoming chapters.Java enumeration:Enumerations are described in Java 5.0. Enumerating one variable is limited to one of only a few predefined values. The value in this enumeration list is called an enumeration.As you use enumerations, you can reduce the number of error codes.For example, if you consider a fresh ju
This article introduces the content of PHP learning in the string, now share to everyone, the need for friends can refer to
Create
PHP supports 4 ways to create a string: single quotes, double quotes, heredoc grammatical structure, and nowdoc grammatical structure.
1. Single quotation marks
In single-quote strings, variables and special characters are not replaced by escapes, except for backslashes and single quotes themselves:
