Check Transparent native-to-ascii conversion? See details

What is UTF-8 BOM? Project compilation error: java illegal character \\?_illegal character\\?-CSDN blog
UTF-8 BOM is also called UTF-8 signature. BOM, byte order mark.
 
The BOM of UTF-8 is to support UTF-16 and UTF-32. The BOM signature means to tell the editor what encoding the current file uses to facilitate the editor's identification.
 
However, although the BOM is not displayed in the editor, it will produce output, as if there is an extra blank line.

Why is the full name of idea (IntelliJ IDEA) so strange?
Answer: Actually, it’s not surprising. This software company was based on Eclipse when it was founded.
Question: So what happened?
Answer: The name comes from a conversation why u use Eclipse? i have no idea
intelligent idea

File | Settings | Keymap | **Eclipse**
My personal suggestion is that if you are used to ideas, it is good to use the ones that come with them

Software problem solving

Development stuck

Configure VM Options to change startup configuration parameters
  • Select Help in the top navigation bar and click Edit Custom VM Options
  • We modify it appropriately (according to the configuration of the personal computer) and save the file::
-Xmx1024m // The maximum memory limit is: 1024MB (1GB) | java heap maximum value, the maximum memory used
-Xms256m // The initial memory allocation size is: 256MB | Initial Heap size, the minimum memory used, this value should be set larger when the CPU performance is high
-XX:ReservedCodeCacheSize=128m //Code buffer size: 128MB
-XX: + UseG1GC
-server: must be used as the first parameter, for better performance when using multiple CPUs
-XX:PermSize: Set the permanent storage area of the memory
-XX:MaxPermSize: Set the maximum memory permanent storage area
-XX:MaxNewSize:
 + XX:AggressiveHeap makes Xms meaningless.
-Xss: Stack size of each thread
-verbose:gc real garbage collection information
-Xloggc:gc.log specifies the garbage collection log file
-Xmn: the heap size of the young generation, generally set to 3 or 1/4 of Xmx
-XX: + UseParNewGC: shorten minor collection time
-XX: + UseConcMarkSweepGC: shorten the major collection time

-Xmx4096m
-Xms4096m
-XX:ReservedCodeCacheSize=256m
-XX: + UseG1GC
  • Make the configuration effective: Select File ---> Invalidate Caches (clean up invalid caches)
  • Keep the default options, select OK to clear cache and restart IDEA (End).

Increase compilation memory (required)

File | Settings | Build, Execution, Deployment | Compiler

  • Share build process heap size (Mbytes) 2048
Uninstall unnecessary plug-ins (optional)

Open settings-plugins
Everything that has nothing to do with Java development can be uninstalled.

Turn off compilation checking

Appropriately turn off the inspection of Inspections of the idea or completely turn off the inspection of Inspections during development, and then turn on the inspection after the development is completed. You can close them all. There is a head logo in the lower right corner of the idea. You can click it to adjust the idea inspection level~

Change operating system shortcuts

First of all, after installing the IDEA software, the automatically generated desktop startup methods are all 32-bit. If you have a 64-bit system and we use this shortcut to run large projects, it will usually be very laggy. Find the installation directory of idea, enter the bin file, find the program named idea64, generate a shortcut, and use this shortcut to start

Close alibaba code review

You can turn it off during development, Alibaba check plug-in Alibaba Java Coding guide

Increase memory

If your development machine does not have enough memory 8<=RAN, you should still think about how to increase the machine’s CPU usage and RAM usage.
