slack code block

ObjectiveMarch 1, 2018 lunar month 14 ThuI do not know how, early in the morning to work to write a blog;Xcode code blockDevelopment, do not want to write too much code, and then will use this method, to simplify the code, including the MVVM framework, it is also reflected to simplify the c inside of the garbage code,

In the lower-right corner of the Xcode, there is an icon with two curly braces, which is the custom code block. For example, the following figure is a for-loop system custom code block, drag it into the code area, it can be used directly, very convenient. The following is

Run the following code and observe the results: Package com.test; public class Hellob extends Helloa {public Hellob () { } { System.out.println ("I ' M B class"); } static { System.out.println ("Static B"); } public static void Main (string[] args) { new Hellob (); } } Class Helloa {public Helloa () { } { System.out.println ("I ' M A class"); } static { System.out.println ("Static

One, synchronized synchronous statement block: Before introducing the synchronization statement block, do an experiment to verify that the order in which multiple threads call the same synchronization method is random. Example one: 1) Mylist.java 2) Test: It is visible that the code in the synchronization method is printed synchronously, but thread A and thread

Original English: Lauri Hartikka The basic concept of a block chain is simple: a distributed database that stores an ever-growing list,list containing many sequential records. In general, however, when we talk about block chains, we also talk about the problem of using block chains, which can easily be confused. This is the case for a

floating, the parent p will not be the following two P package, but still within the range of the parent p, left floating is the left of the child p contact the left side of the parent p BorderBox, the right float is the child p contact the parent p BorderBox right, This is always the rule unless you set the margin to open the distance. Areas of the BFC layout rule 4:bfc do not overlap with float box: The above aside box has a floating property that overrides the contents of the main box, and
