Java Check Directory For Zip Files

I have the below code which checks to see if folder exists on the sdcard, I would like to add another if statement if the folder exists to check that there are zip files inside the

Solution 1:

Filef=newFile("folder");
FilenameFilterf2=newFilenameFilter() {
publicbooleanaccept(File dir, String filename) {
return filename.endsWith("zip");
}
};
if (f.list(f2).length > 0) {
// there's a zip file in there..
}

Try the above..

Solution 2:

Have you looked at FileNameFilter ?

File f = newFile("/mnt/sdcard/folder");
if(e.exist()){//file exist ??File[] matchingFiles = f.listFiles(newFilenameFilter() {
    publicbooleanaccept(File dir, String name) {
        return name.endsWith("zip");
    }
});//list out files with zip at the end

}
