StringTokenizer to remove 3 consecutive words

[Peter Primrose]

Hi guys,

look at my code below. my goal is to eliminate the words "on the moon" from the sentence: "there is a man on the moon with a dell computer";

I receive this result:

r is a a wi a DELL cpur

 
import java.util.*; 
 
  
public class Editor 
{
public static void main(String args[])
{
String str = "there is a man on the moon with a DELL computer";
System.out.println(str.length());
System.out.println("str:="+str);
String s="";
 
String del="on+the+moon";
 
StringTokenizer st = new StringTokenizer(str, del);
while(st.hasMoreTokens())
{
  s+=st.nextToken();
  }

System.out.println("str:="+s);
}

 
}
 

can any one help?

Tell me more about what this program is supposed to do:
Are you going to give it other phrases to remove from other
strings, or will you always be removing the words "on the moon"
from all input or what?

When you specify your delimiter as "on the moon" you are telling StringTokenizer that you want to use all of the seperate letters in that sentance as delimiters not the actual String itself. You are better off using the split command or something equivalent.

import java.util.*;
 

public class Editor
{
public static void main(String args[])
{
String str = "there is a man on the moon with a DELL computer";
System.out.println(str.length());
System.out.println("str:=" + str);
String s="";

String del="on the moon";

String[] result = str.split(del);
for (int x=0; x<result.length; x++)
    s+=result[x];

System.out.println("str:=" + s);
}
}  

Hope this helps!

thank you Elouise for your prompt replt.

Basically, it suppose to remove only once the 3 word "on the moon" so the end result will be:

"there is a man with a DELL computer"

any suggestions?
