Instalasi Kompiler & Interprinter
Mendistribusikan web di server [Linux] dan menggunakan kompiler Linux saat memasukkan teks dari luar.
Lai Itu harus Korea di Linux Environment -C-
Manakah dari GCC dan G ++ yang Anda pilih?
Jika Anda mengirim perintah ke Linux di Java, ketidaksetaraan tidak akan mengenalinya?
Gcc -o test test.c 2> error.txt tidak dapat dieksekusi sendiri
Otoritas di atas adalah masalah, tetapi bukan masalah yang harus dipertimbangkan dalam tahap perkembangan saat ini.
Kesimpulan) Pertama, buat file C dan tafsirkan frasa yang tidak dapat ditafsirkan Java. Tafsir ulang dengan membuat frasa yang sebelumnya diperintahkan di Java ke dalam file yang dapat dieksekusi.
-Jawa-
Implementasi Kompiler Java Berdasarkan Implementasi Kompiler C dengan GCC
Berbeda dari GCC
Kesimpulannya, seolah -olah Anda memproduksi kompiler C, interpretasi java sebagai gantinya
docker exec se03 sh -c "cd compile; javac -encoding utf-8 javaTest.java 2> javaError.txt"
docker exec se03 sh -c "cd compile; java -Dfile.encoding=utf-8 SELAB > javaResult.txt"
-PYTHON-
- python은 인터프린터 언어로 컴파일 과정을 거치지 않느다. 그점에서 위의 JAVA와 C Compiler와 상호 다른 부분이 존재했다.
1) 실행 결과 python python.py를 실행하면 즉각적으로 결과가 출력됨
- 오류출력은? 어떻게?
1) 표준 에러 출력을 pythonError.txt파일에 입력시킨다.
2) pythonError.txt 파일에 데이터가 입력된 상태이면 실행이 성공한 것으로 생각하고 결과값을 유도받는다.
- 오류출력에 문제점이 발생할 경우 또는 .py 파일의 데이터가 쌓이는 겨우
1) 제일 먼저 실행될 리눅스 명령문을 .py 파일과 pythonError.txt파일을 지우도록 했다.
2) 기존 데이터를 지움으로써 이후에 입력될 내용들의 오류를 잡는다.
2) python 한글 패치
- `# -*- coding: utf-8 -*-`
-JS-
- JS는 python과 같은 인터프린터 언어이다. 자바와 c언어처럼 별도의 컴파일 과정을 거치지 않는다. 그러므로 이를 해결하기 위해서 python과 같은 구조로 해석문 구조를 구현했다.
1) 실행 결과 js hello.js를 실행하면 즉각적으로 결과가 출력됨
- 오류출력은? 어떻게?
1) 표준 에러 출력을 jsError.txt파일에 입력시킨다.
2) jsError.txt 파일에 데이터가 입력된 상태이면 실행이 성공한 것으로 생각하고 결과값을 유도 받는다.
- 오류출력에 문제점이 발생할 경우 또는 .js 파일의 데이터가 쌓이는 경우
1) 제일 먼저 실행될 리눅스 명령문을 .js 파일과 js.txt파일을 지우도록 함
2) 기존 데이터를 지움으로써 이후에 입력될 내용들의 오류를 잡음

Kesalahan terjadi selama MySQL yang saling terkait?
Kesimpulan) Pindah ke MySQL-Connector-Java-5.1.45.jar-> tomcat-> lib
ID Database: Selab
Database PW: 1234
Kode tidak disimpan?
Hasil) Keanggotaan hanya dapat didaftarkan dengan ID keanggotaan yang telah bergabung di web !!

JavaScript mirip dengan interprinter Python yang ada, sehingga dapat diimplementasikan secara sederhana.
