Console

Console

The console UI uses the implemented operations of the file system to allow the user to interact with it.

The ConsoleUI.java class has a static variable that stores the current directory the user is in. Every time it changes (by using the command cd) it is updated.

In order to process user input and commands, the Strategy pattern was implemented to allow new features to be added easily in the feature.

    static {
        commands.put("cd", new ChangeDir());
        commands.put("cp", new Copy());
        commands.put("mv", new Move());
        commands.put("ls", new ListDir());
        commands.put("touch", new CreateFile());
        commands.put("mkdir", new CreateFolder());
        commands.put("rm", new Delete());
        commands.put("cat", new ShowFileContent());
    }
