Décompiler Java
L'environnement est Ubuntu 16.04
La source du fichier de classe que j'ai créé il y a environ 10 ans manque, je l'ai donc décompilé.

Jad 1.5.8e for Linux on Intel platform (214917 bytes).
Jad 1.5.8e for Linux (statically linked) (389972 bytes) - take this version if the one above crashes or displays the "seek error" message.
Après avoir téléchargé et exécuté ce qui précède
./jad: error while loading shared libraries: libstdc++-libc6.2-2.so.3: cannot open shared object file: No such file or directory
Depuis qu'il est devenu, téléchargez ce qui suit et exécutez-le. Essayez de décompiler ../PDFConverter.class.
$ ./jad ../PDFConverter.class
Parsing ../PDFConverter.class...The class file version is 49.0 (only 45.3, 46.0 and 47.0 are supported)
Generating PDFConverter.jad
Overlapped try statements detected. Not all exception handlers will be resolved in the method main
Couldn't fully decompile method main
Couldn't resolve all exception handlers in method main
Ah, (seuls 45,3, 46,0 et 47,0 sont pris en charge). Je pensais que cela ne fonctionnerait pas, mais un fichier appelé PDFConverter.jad a été créé.

Puisque la capture d'écran est Windows, j'ai eu un mauvais pressentiment, mais je suis soulagé par le multi-plateforme. Téléchargez jd-gui_1.4.0-0_all.deb.
$ sudo dpkg -i jd-gui_1.4.0-0_all.deb
[sudo]mot de passe nanbuwks:
Package jd précédemment non sélectionné-gui est sélectionné.
(Chargement de la base de données...Actuellement, 793826 fichiers et répertoires sont installés.)
jd-gui_1.4.0-0_all.Préparation du déploiement de deb...
jd-gui (1.4.0-0)Déploie...
jd-gui (1.4.0-0)Est réglé...
Appelez et exécutez JD-GUI à partir de Dash of Unity
J'ai bien fait.
