Class TextFileReader

  +--TextFileReader

public class TextFileReader

extends Object

The TextFileReader class is an actor class which reads input from a specified file one sentence at a time. Sentences are assumed to be terminated with one of the following characters: '.', ':', ';', '?' or '!'.

To read input from a file named TestInput.txt, create a TextFileReader as follows:

String filename = "TestInput.txt"; TextFileReader reader = new TextFileReader(filename);

Once a TextFileReader has been created, each call to the nextSentence method returns a new Sentence object containing the next sentence from the input file. Once all sentences have been read, the nextSentence method returns null. Thus, the following code would read every sentence in the TestInput.txt file:

Sentence s = reader.nextSentence(); while (s != null) { s = reader.nextSentence(); }
