1. Order of Execution1.1. The order of initialization in a class(static variable, static initialization block) = = (variable, initialization block, constructor).1.2, two initialization order with inheritance relationship classesThe parent class (static variable, static initialization block) is the subclass (static variable, static initialization block) and the parent class (variables, initialization blocks, constructors) and subclasses (variables, ini

1. Static initialization block　　Static initialization blocks are only executed once when the class is first loaded , while static initialization blocks can only assign values to static variables and cannot be assigned to normal member variables.2. (non-static) initialization block　(non-static) initialization blocks are executed once each time the instance object

. Access class variables through any instance of the class, and the underlying will turn them into class variables through the class itself, with the same effect 5. Once the value of the class variable is changed, the class variable is accessed through any instance of the class or class, and the resulting value is changed. 6. The class will be initialized before the initialization of the instance variable (non-static variable) 1. Cannot forward reference, if forward reference, is called illegal

AutoCAD in the selection of the editor has a lot of skills, we collect the summary here, I hope to help you. In the selection of AutoCAD Editor, sometimes accidentally select an entity, at this point in the command does not end the need to cancel the command and restart, only to "select the target" after the prompt input remove carriage return, and then in the hint to select which multiple of the selected

The creation of hatches differs from other entities such as blocks, text styles, and callout styles, and the approximate method and procedure are basically the same, only in individual places. To create a Hatch object, first use the class's constructor to create an empty fill object, and then set the properties for the object's type, style, name, fill angle, and bounds. Steps are as follows1. Create a pattern boundary:Create a fill boundary with the C

In Java and Android, what is the difference between the execution order of blocks of code and static code blocks?JavaLet's start with a simple example.Main.java:publicclass Main { staticint1; static { System.out.println(a); } static { 2; } publicstaticvoidmain(String[] args) { System.out.println("Hello World!"); System.out.println(a); }}Output to 1He

Building blocks: Code blocks that are written directly in a classStatic code collapse: blocks of code declared with the static keywordStatic code blocks are constructed before the construction block, and are executed only once when the class is loaded, and later when the class is instantiated, the building

In mechanical engineering drawing, the Central line is the most common kind of graph line, the application scope is very wide, the use is very frequency tight. Although AutoCAD provides the command to draw straight lines, but does not directly provide the command to draw the standard centerline, if the user wants to draw the standard centerline, it is necessary to set the line style and proportion of the standard centerline according to the national d

The coordinate system of AutoCAD is divided into world coordinate system and user coordinate system. 1 World coordinate system (WCS) Figure 1-1-1 The world coordinate system is the default coordinate system defined by the AutoCAD System. When we open a new graph, we enter the world coordinate system. It is similar to the familiar dikar coordinate system. The horizontal axis is the X axis, the vertical

The following will enter the graphics space provided by AutoCAD for the user. The main purpose is to use AutoCAD to draw graphics, so first of all to understand the Graphics object in the environment. As we have seen in real life, AutoCAD provides a three-dimensional space, and usually our modeling work is done in such a space.
