Question

Write a static method named fixSpacing that accepts a Scanner representing a file as a parameter and writes that file's text to the console, with multiple spaces or tabs reduced to single spaces between words that appear on the same line.

For example, if the input file contains the following text,

four      score   and

seven              years ago         our

fathers brought             forth

    on this          continent

a         new

nation

then your method should produce the following output:

four score and

seven years ago our

fathers brought forth

on this continent

a new

nation

Notice that some lines might be blank. Each word is to appear on the same line in the output on which it appears in the input file.

Explanation / Answer

// This program removes excess space in an input file. import java.io.*; import java.util.*; public class FixSpacing { public static void main(String[] args) throws FileNotFoundException { Scanner input = new Scanner(new File("words.txt")); PrintStream output = new PrintStream(new File("words2.txt")); while (input.hasNextLine()) { String text = input.nextLine(); echoFixed(text, output); echoFixed(text, System.out); } } public static void echoFixed(String text, PrintStream output) { Scanner data = new Scanner(text); if (data.hasNext()) { output.print(data.next()); while (data.hasNext()) { output.print(" " + data.next()); } } output.println(); } }
