It is given that the file(a.txt) is already exist. Why we need new File(a.txt) in constructor parameter. Can anyone please explain?

Scanner sc=new Scanner (new File(a.txt));

Because "new File(...)" does not create a file - it creates a File object. You need a File object to work with existing files as well as new files.
