===========================Rename/Move a file (to a new directory)=======================
https://mkyong.com/java/how-to-rename-file-in-java/
In Java, we can use the NIO Files.move(source, target) to rename or move a file.


import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;

  //...

  Path source = Paths.get("/home/mkyong/newfolder/test1.txt");
  Path target = Paths.get("/home/mkyong/newfolder/test2.txt");

  try{

    Files.move(source, target);

  } catch (IOException e) {
    e.printStackTrace();
  }
