Given that the current directory is empty, and that the user has read and write permissions, and the following:
import java.io.*;
public class DOS {
public static void main(String[] args) {
File dir = new File("dir");
dir.mkdir();
File f1 = new File(dir, "f1.txt");
try {
f1.createNewFile();
} catch (IOException e) { ; }
File newDir = new File("newDir");
dir.renameTo(newDir);
}
}
Which statement is true?
