Java JFileChooser is a class in the Java Swing user interface toolkit that provides a graphical file chooser dialog for selecting files and directories. It allows users to browse through the file system, select one or more files or directories, and optionally specify a filename filter or a file view to control what files are displayed in the file chooser dialog.
JFileChooser provides a flexible and customizable interface that allows developers to specify various configuration options, such as the initial directory, file selection mode, and dialog title. It can be used in various types of Java applications, such as desktop applications, applets, and servlets, to enable users to select files and directories in a convenient and user-friendly way.
JFileChooser was introduced in Java 1.2 and has been part of the Java Swing API ever since. It is widely used in Java applications for file selection and management tasks.
