Question

Up to now I have used classes like Scanner and BufferReader/Writer, to read from a given txt file and write certain information to a txt file.

I want to implement a class that basically will do the same things as the Scanner class, meaning, will be able to parse a line of information from the file so that I can do certain stuff with this information.

My problem is I cannot find an Interface class in the java API that does this thing. And I am not sure if the Iterator interface can be used for this.
Should I write one in my own?

Thanks

Absolutely not, when you can use Scanner or BufferedReader which is provided inside the java library.

For any reason, if you do not want to project the usage of scanner then;

class MySpecialReader {

  private Scanner scanner;

  readData(){
     //use the scanner to read the data.
     //You can convert the checked exceptions to Runtime etc..
  }
}
