The reason why HashMap multithreads send out life and death loops
This article is a learning record of Vaccine: Java HashMap’s endless loop, welcome to discuss ~
Suppose the state of a cylinder to be expanded is as follows:
1->; 2-> Null
1 for the current thread to insert a new element of an array of e: 1 and the next element next:
when thread 2 completed the expansion, the pointer to the current status to 2 – & gt; 1-> NULL
Thread 1 continues:
rst (e:1,next:2)
n>arrel :1 ->; null
e=next=2;
next=e1.next=1;
> (e:2,next:1)
> 1-> null
e=next=1;
next=e1.next=null;
(e:1,next:null)
new barrel :1 ->; 2-> 1 is just 1 lt; -> 2
e=next=null;

Eclipse cannot import org.apache.log4j .Logger
Recently, I’ve been practicing using log4j, but I keep getting errors when importing from Eclipse
But I have already imported it in the lib below
I guess the JAR package was not imported
If you want to place the JAR under the JDK, right-click and select Build Path –>; Configure Build Path
Then select Add Externsl Jars
Select the package we want to import
Then click Apply and it’s OK.

Idea has installed markdown, open it or will not show preview effect
Idea has Markdown installed and will not show the preview effect
why
This is because the.md file at the end of the Markdown plugin was opened using Text, so idea is now opened using Text.
The solution
In the file - & gt; The Settings - & gt; The Editor - & gt; File Types under Recongnized the File Types found under Markdown , then click on the Registered Patterns bar to the right of the plus sign, fill in the * md save. The .mdle has been registered in Text.
