Answer 1

This is an easy way to rename a file:

        File oldfile =new File("test.txt");
        File newfile =new File("test1.txt");

        if(oldfile.renameTo(newfile)){
            System.out.println("File renamed");
        }else{
            System.out.println("Sorry! the file can't be renamed");
        }
