15.6 Opening Files with JFileChooser

Class JFileChooser displays a dialog that enables the user to easily select files or directories. To demonstrate JFileChooser, we enhance the example in Section 15.3, as shown in Figs. 15.12–15.13. The example now contains a graphical user interface, but still displays the same data as before. The constructor calls method analyzePath in line 24. This method then calls method getFileOrDirectoryPath in line 31 to retrieve a Path object representing the selected file or directory.
