java 的jdk裡的File類沒有提供按日期或大小排序來取的目錄下檔案列表的功能.

所以只能自己寫一個了.簡單實現.

以下是程式碼:

public class Log { public static void main(String[] args) { File file = new File("d:/"); File [] fs = fil.listFiles(); Arrays.sort(fs, new Log.CompratorByLastModified()); for (int i = 0; i < fs.length; i++) { System.out.println(new Date(fs[i].lastModified()).toLocaleString()); } } static class CompratorByLastModified implements Comparator<File> { public int compare(File f1, File f2) { long diff = f1.lastModified()-f2.lastModified(); if(diff>0) return 1; else if(diff==0) return 0; else return -1; } public boolean equals(Object obj){ return true; } } }
