通过java批量修改文件的修改时间

package test;import java.io.File;import java.io.IOException;public class test {public static final String PATH = "F://Test//测试";public static void main(String[] args) {long date = System.currentTimeMillis();long day = 86400 * 30;for (int i = 1; i < 101; i++) {File mFile = new File(PATH + " " + "(" + i + ")" + ".png");System.out.println("#############" + System.currentTimeMillis());long modifytime = ((date / 1000) + day * i) * 1000;System.out.println("####111#########" + mFile.lastModified());mFile.setLastModified(modifytime);System.out.println("####222#########" + mFile.lastModified());try {mFile.createNewFile();} catch (IOException e) {e.printStackTrace();}}}}
