Create a folder with a given name

Question

I’m trying to create a folder with a certain name but I don’t know why it always appears bin+name.

Example: If secondArg = dot then the folder name becomes bindot.

Is it because I’m running in the terminal? Since when I run in the terminal I have to go to the project folder and then to the bin in order to run the class. How can I solve?

private void makeDir(String secondArg) {
        File theDir = new File(System.getProperty("user.dir") + secondArg);

        // if the directory does not exist, create it
        if (!theDir.exists()) {
            System.out.println("creating directory: " + theDir.getName());
            boolean result = false;

            try{
                theDir.mkdir();
                result = true;
            } 
            catch(SecurityException se){
                //handle it
            }        
            if(result) {    
                System.out.println("Repository " + theDir.getName() + " was been created");  
            }
        }

    }

Missing a folder separator:

private void makeDir(String secondArg) {
        File theDir = new File(System.getProperty("user.dir") + File.separator + 
 secondArg);

        // if the directory does not exist, create it
        if (!theDir.exists()) {
            System.out.println("creating directory: " + theDir.getName());
            boolean result = false;

            try{
                theDir.mkdir();
                result = true;
            } 
            catch(SecurityException se){
                //handle it
            }        
            if(result) {    
                System.out.println("Repository " + theDir.getName() + " was been created");  
            }
        }

 }

I used File.separator instead of bars(\ or /) because this is the responsibility of the running operating system to define.
