Rename file or directory in Java
The method java.io.File.renameTo() is used to rename a file or directory. This method requires a single parameter i.e. the name that the file or directory is renamed to and it returns true on the success of the renaming or false otherwise.
A program that demonstrates this is given as follows −
Example
import java.io.File;
public class Demo {
public static void main(String[] args) {
try {
File file1 = new File("demo1.txt");
File file2 = new File("demo2.txt");
file1.createNewFile();
file2.createNewFile();
boolean flag = file1.renameTo(file2);
System.out.print("File renamed? " + flag);
} catch(Exception e) {
e.printStackTrace();
}
}
}The output of the above program is as follows −
Output
File renamed? true
Now let us understand the above program.
The method java.io.File.renameTo() is used to rename the file. Then the boolean value returned by the method is printed. A code snippet that demonstrates this is given as follows −
try {
File file1 = new File("demo1.txt");
File file2 = new File("demo2.txt");
file1.createNewFile();
file2.createNewFile();
boolean flag = file1.renameTo(file2);
System.out.print("File renamed? " + flag);
} catch(Exception e) {
e.printStackTrace();
}
