Answer 1

// You'll need this import: import java.io.File;

File folder = new File("C:/Folder_Location");
// gets you the list of files at this folder
File[] listOfFiles = folder.listFiles();
// loop through each of the files looking for filenames that match
for(int i = 0; i < listOfFile.length; i++){
    String filename = listOfFiles[i].getName();
    if(filename.startsWith("Stuff") && listOfFiles[i].getName().endsWith("OtherStuff")){
        // do something with the filename
    }
}

Answer 2

Probably the easiest way is to simple use File#listFiles(FileFilter), something like

File[] fileList = new File("/path/to/search").listFiles(new FileFilter() {
    @Override
    public boolean accept(File pathname) {
        return pathname.getName().endsWith(".txt");
    }
});

Answer 3

File#getName() should return aString`, then use:

filename.startsWith(...);
filename.endsWith(...);
