Java.io.File does not contains any ready make move file method, but you can workaround with the following two alternatives :
- File.renameTo() 
- Copy to new file and delete the original file. - public class MoveFileExample 
{
  public static void main(String[] args)
  { 
  try{
   File afile =new File("C:\\folderA\\Afile.txt");
   if(afile.renameTo(new File("C:\\folderB\\" + afile.getName()))){
    System.out.println("File is moved successful!");
   }else{
    System.out.println("File is failed to move!");
   }
}catch(Exception e){
    e.printStackTrace();
}
}
}
 
For Copy and delete
public class MoveFileExample 
{
    public static void main(String[] args)
    {   
        InputStream inStream = null;
    OutputStream outStream = null;
        try{
            File afile =new File("C:\\folderA\\Afile.txt");
            File bfile =new File("C:\\folderB\\Afile.txt");
            inStream = new FileInputStream(afile);
            outStream = new FileOutputStream(bfile);
            byte[] buffer = new byte[1024];
            int length;
            //copy the file content in bytes 
            while ((length = inStream.read(buffer)) > 0){
                outStream.write(buffer, 0, length);
            }
            inStream.close();
            outStream.close();
            //delete the original file
            afile.delete();
            System.out.println("File is copied successful!");
        }catch(IOException e){
            e.printStackTrace();
        }
    }
}
HOPE IT HELPS :)
