There are certain files created by particular editors, IDEs, operating systems, etc., that do not belong in a repository. But adding system-specific files to the repo's .gitignore is considered a poor practice. This file should only exclude files and directories that are a part of the package that should not be versioned (such as the node_modules directory) as well as files that are generated (and regenerated) as artifacts of a build process.

All other files should be in your own global gitignore file. Create a file called .gitignore in your home directory and add anything you want to ignore. You then need to tell git where your global gitignore file is.


git config --global core.excludesfile ~/.gitignore


git config --global core.excludesfile %USERPROFILE%\.gitignore


An RPN calculator computes expressions written in Reverse Polish Notation.

An RPN expression or postfix expression is one of the following :

  • a number X, in wich case the value of the expression is that of X,
  • a sequence of form E1 E2 OP where E1 and E2 are RPN expressions and OP is an arithmetic operation.

Samples :



  • CLI: mauvaise gestion --help; privilégiez un contains plutôt qu'un args.length==1
  • Déclaration des types List<Operator> ... plutôt que ArrayList<Operator> ...
  • Dommage de pas avoir fait une classe Operators, qui aurait pu contenir la recherche du bon operateur plutôt que la boucle for dans la classe Calculator
for(Operator operator : operations){
