How do I use filters when listing the contents of a directory?
The easiest way is to use an anonymous inner class which implements either FileFilter or FilenameFilter:
//list only pdf files
File[] pdfFiles = departmentFolder.listFiles(new FilenameFilter(){
public boolean accept(File dir, String name){
return (name.endsWith("pdf")||name.endsWith("PDF"));
}
});
|
//list only folders
File[] usrFolders = departmentFolder.listFiles(new FileFilter(){
public boolean accept(File pathname){
return (pathname.isDirectory());
}
});
