JAVA (First step: Git Bush edition)

For me, who was a beginner, I felt that it was a fairly precise language. I just stumbled, but as I got used to it, my understanding seemed to deepen.

Before that, I often use discord for exchanging codes and files.

It seems to be convenient when developing with a large number of people or educational development. I feel good with Slack.

Check the location first

pwd /*Check the current location display*/

To prevent garbled characters

vi ~/.bashrc 

Paste this

　　alias javac='javac -J-Dfile.encoding=UTF-8'
  　alias java='java -Duser.language=ja -Dfile.encoding=UTF-8'
  　sc(){
  　start chrome $1
   }

Exit and save

　ctrl +from c:wq　

Move to any location

cd folder name//cd test/Test2 and time saving movement are also possible

Create a folder

mkdir folder name

Create and open a file with vim in the moved folder

vi folder name.java

Try to describe

public class Main{
  public static main(String[] arrgs){
     System.out.println("Hello World!");
  } 
}

save

ctrl +Exit insert mode with c:wq

compile

$ javac Main.java

compile

$ java Main
Hello World!　//Is output, ok

That's all
