How to read blank in java

Question

hi guys, im totally confused about how to read blank ( no character, or space ) in order to proceed my line counter program.
thanks

Answer 1

i'm trying to make the program read from a textfile, and trying to do like if there is a blank then assume we can go to the next line and that blank is count as 1 line.
this is my code so far.
import java.io.*;
import java.util.*;
public class Test
     public static void main(String[] args)
                              throws FileNotFoundException
          FileReader inFile = new FileReader ("test.txt");
          PrintWriter outFile = new PrintWriter("testResult.txt");
               int numLines = 0;
               int numWords = 0;
               int numChars = 0;
               String line;
               do {
                    line = inFile.nextLine();
                    if (line != " ")
                         numLines++;
                         numChars += line.length();
                         numWords += countWords(line);
               while (line != " ");
               System.out.println("The following text has: " + "\n" + numLines + " Lines" + "\n" +
               numWords + " Words " + "\n" + numChars + " Characters");
     private static long countWords(String line)
               int numWords = 0;
               int index = 0;
               boolean prevWhitespace = true;
               while (index < line.length())
                    char c = line.charAt(index++);
                    boolean currWhitespace = Character.isWhitespace(c);
                    if (prevWhitespace && !currWhitespace)
                         numWords++;
                    prevWhitespace = currWhitespace;
               return numWords;
}and sorry for offtopic here, but i also getting an error here.
