過濾文件的.在lis和listFiles方法中使用.

~~~
File dir = new File("./");
FileFilter ff = new FileFilter()        //FileFilter是一個接口,需要一個實現類,這里使用了匿名內部類.重寫accept方法
{
    @Override
    public boolean accept(File pathname)
    {
        if (pathname.getName().endsWith(".jpeg")) {
            return true;
        }
        return false;
    }
};

File[] files = dir.listFiles(ff);

for (File file : files) {
    System.out.println(file);        //這里獲取了.jpeg結尾的文件
}
