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();
}
}
}
}
