Nah... that sound's too much like C/C++ thinking.  Java deals more with
strings and tokens, rather than character arrays with null terminators.

Try something like this:

/*********/
import java.io.*;
import java.util.*;

public class delWord {
  
  public static void main (String av[]) {

    try {
      
      BufferedReader is = new BufferedReader(
        new InputStreamReader(System.in));
      String inputLine;
      StringBuffer outputLine;
      String wordToDelete = "and";
      StringTokenizer words;
      String curWord;

      while ((inputLine = is.readLine()) != null) {
        words = new StringTokenizer(inputLine);
        
        while (words.hasMoreTokens()) {
          curWord = st.nextToken();
          
          if (!curWord.equals(wordToDelete)) {
            System.out.print(curWord);
          }
        }
      }
      is.close();
    } catch (IOException e) {
      System.out.println("IOException: " + e);
    }
  }
}
/********/

Run this with:

$ java delWord < inputFile > outputFile

Something like that would work.  I'm not a certified Java hacker, but I
did stay a a Holiday Inn Express last night. :)
