package c10; import java.io.*;
public class DirList { public static void main(String[] args) { try { File path = new File("."); String[] list; if(args.length == 0) //请问这句话在这里的作用 list = path.list(); else list = path.list(new DirFilter(args[0])); //这里的args[0]是代表的c10? for(int i = 0; i < list.length; i++) System.out.println(list[i]); } catch(Exception e) { e.printStackTrace(); } } }
class DirFilter implements FilenameFilter { String afn; DirFilter(String afn) { this.afn = afn; } public boolean accept(File dir, String name) { // Strip path information: String f = new File(name).getName(); return f.indexOf(afn) != -1; } } ///:~ 希望各位高手解释下这段代码,主要是代码中args[]的使用,谢谢
