Rename a file using Java

Question

Can we rename a file say test.txt to test1.txt ?

If test1.txt exists will it rename ?

How do I rename it to the alrea

Answer 1

import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import static java.nio.file.StandardCopyOption.*;

Path yourFile = Paths.get("path_to_your_file\text.txt");

Files.move(yourFile, yourFile.resolveSibling("text1.txt"));

To replace an existing file with the name "text1.txt":

Files.move(yourFile, yourFile.resolveSibling("text1.txt"),REPLACE_EXISTING);
