java 的jdk里的File类没有提供按日期或大小排序来取的目录下文件列表的功能.
所以只能自己写一个了.简单实现.
以下是代码:
import java.io.File;
import java.util.Arrays;
import java.util.Comparator;
import java.util.Date;
public class Log {
public static void main(String[] args) {
File file = new File("d:/");
File[] fs = file.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;
}
}
}
