String Tokenizing Help

I'm having problems with looking through a sentence for a word in my case the word breakfast should be found and the result should be "found" but it is doing my 'else' what am I doing wrong with the IndexOf i have been looking at this for hours on the net and its confused me, any help would be great.
static String findWord() {
String result = "";
String sentence = "I like a good breakfast";
StringTokenizer st = new StringTokenizer(sentence);
while (st.hasMoreTokens()) {
String temp = st.nextToken();
if (temp.indexOf("breakfast") > 0) {
result = "found";
} else
...... code omitted ... do something else.

yep, returns "found"
public static string findWord() {
      String result = "not found";
      String sentence = "I like a good breakfast";
      if (sentence.indexOf("breakfast") >= 0)       {
        result = "found";
      else
return result;
[\code]
sounds like a short circuit between keyboard and ground !!

Guys I need some help. String token of a wired message

let me explain a lil. The program is actually a daemon. It works fine. In the body run, that's the thingy which did string token. It works fine. But
i am creating something that will split (1a) into 2 piece, and another will spilt the other piece.
The senario, the daemon will receive a string, like "*abcde,1,2,3,hello%"
where * = STX (ASCII 02) and % ETX (ASCII 03)
the first loop will eliminate the STX, then seggregate the text to a loop, for example a=abcde, b=1, c=3, d=hello%.
*what i managed to do is only string token the normal characters, not the ASCII characters
then the final loop will grab strtoken the % char.
i have been trying tht for 1 whole days.. n e ideas guys ?
thanks in advance.

Arraylist and string split help

i want to add items from a textfile into an array list here is the txt file
Title,Artist
tester,test
rest,test
red, blue
here is the code i am using
try{
FileReader fr = new FileReader(fileName);
BufferedReader br = new BufferedReader(fr);
String s;
int c = 0;
while((s = br.readLine()) != null) {
c=c+1;
CD c3 = new CD("");
String tokens[] = s.split(",");
        for(String token : tokens) {
      System.out.println(c);
       System.out.println(tokens.toString());
          if ( c == 2){
            c3.setTitle(token);
                System.out.println(c);
                 System.out.println(token);

Spliting a string -- need help

hai everybody,
i have a string say
str="1,5,10,12"; //dynamic values
i need to spilt this string and assign values like
if 1 then "one"
if 2 then "two"
if 10 then "ten"
how can i do this.can i use array or stringTokenizer.which 1 will sound good.
please anyone help me out.
thanks in advance
regards
Koel

*** Ceranith, if you start your array with String[] words = { "Zero", .....[/b] then you don't need to subtract the 1 when you parse the integer, just a suggestion.
You could try it using a hashTable.java.util.Hashtable hashtable = new java.util.Hashtable();
hashtable.put("0", "zero");
hashtable.put("1", "one");
hashtable.put("2", "two");
hashtable.put("3", "three");
hashtable.put("4", "four");
hashtable.put("5", "five");
String str = "1,3,4,4,4";
java.util.StringTokenizer st = new java.util.StringTokenizer(str, ",");
while (st.hasMoreTokens()) {
String token = st.nextToken();
String value = (String)hashtable.get(token);
System.out.println(value);
}or you could go and do it in code, if you don't feel like adding all the numbers from 1 to 1million...
something along the lines of this... not fully working, I couldn't be bothered, sorry ;-)String theNumber = st.nextToken();
String myNumber = "";
if(Integer.parseInt(theNumber) <= 19) { // don't forget your error handling
myNumber = getNumber(theNumber);
else if( Integer.parseInt(theNumber) <= 99) {
// loop through the number checking each position in the string
// This is the difficult part, which I will leave up to you as an
// exercise (don't you just hate it when people do that ;-)
else if(Integer.parseInt(theNumber) <= 999) {
... etc
public String getNumber(String str) {
return (String)numbers.get(str);
public String getDecade(String str) {
return (String)decades.get(str);
private void init() {
numbers.put("0", "zero");
numbers.put("1", "one");
numbers.put("19", "nineteen");
decades.put("2", "twenty");
decades.put("3", "thirty");
decades.put("9", "ninety");
decades.put("10", "one hundred");
private Hashtable numbers = new Hashtable();
private Hashtable decades = new Hashtable();

Sort a string :: Please help.

Hello Everyone,
I am having this very simple problem of sorting a String. please help.
     static String sortString(String str){
          List list = Arrays.asList(str);
          Collections.sort(list);
          for(int i=0, n=list.size();i<n;i++){
               System.out.println(","+ list.get(i));
The function is supposed to take a String and sort it & print it out. This should be simple. Where am I making mistakes? Please help!!

String Tokenizing Question

Hello -
I'm able to tokenize w/o any problems, save for when I run into consecutive instances of the character, a comma, that I am using for my delimiter. Here's a sample line:
The,lazy,fox,,jumped,,,over,the,,,moon,,,,,
So, if my string has values for each field that the tokenizer looks at, I have no problems, but if there are two or more commas (delimiters) in sequence, it breaks the tokenizer.
So what I'd like to do barring a better/simpler solution is to print "N/A" or something if there is no data in that token and then continue on to assign each (valid) token to a String variable.
Thanks...

Like warnerja suggested/mentioned: try String's
split(...) method:
String s =
"The,lazy,fox,,jumped,,,over,the,,,moon,,,,,";
String[] tokens = s.split(",+");
for(int i = 0; i < tokens.length; i++) {
System.out.println("Token "+(i+1)+" =
"+tokens);
Except get rid of the "+" part, as that just makes it eat the empty tokens. Just use s.split(",")

Split/remove characters for a string token

How can a string token i.e. 2-234-56723-4 have the - removed so that the token is left with 2234567234?
I tried to split it using "-" but that obviously doesnt work, because 234 will be a token, I just want to remove the - from the token.
advice please.

if I want 3-34-565456-4 to be 334565456 so that I can take each digit and do calculations with them, could I just split the string 334565456 using .split(""); which will give me splitArray[0]=3, splitArray[1] = 3, splitArray[2] = 4 etc.
String someStr = "3-34-565456-4";
String numsOnly = someStr.replaceAll("-", ""); //or someStr.replaceAll("[^0-9]", "");
for ( char c : numsOnly.toCharArray() ) {
int digit = c - '0';
}Or
for ( int i = 0; i < numsOnly.length(); i++ ) {
int digit = Integer.parseInt(numsOnly.substring(i, i+1));
What is "digit" ? and doesn't it re-assign a new number to digit each iteration?
Im not sure how I will access each digit.

Urgent help reqd in string tokenizing

hi all,
i want to count the number of commas in the screen,
ths is my code
import java.util.*;
class TokenizerTest
     public static void main(String[] args)
String str= new String("REMOVE_STR,01,6403,40,143,990,410,,,11,ATTN PAT COLEMAN,, ,,,N,,,,,,,,,,,NC,,,,,");
     StringTokenizer st= new StringTokenizer(str,",",false);
     int i=0;
     while(st.hasMoreTokens())
          System.out.println(st.nextToken()+" Val :"+i);
          i++;
     System.out.println("Value of i"+i);
System.out.println("Count is " +st.countTokens());
}but its notgiving the proper count... those commas whcih are not separated by spaces orcharacter, it desn't count like" ,," it won't count theese commas it works fine when commas are separated by spaces or charachters.
what is the solution for this?.. plz help me its urgent
Thanx in advance
Deepali

countTokens() should have been called before the while loop.
so, System.out.println("Count is " +st.countTokens()); should be place before the while loop or create
a local int variable to store the count and use the variable in the
System.out.println("Count is " + count);
The reason why you're not getting the proper count is this:
    In the while loop..you use nextToken()..when this method is called..countToken() method count the total
    number of token left; therefore...after the while loop..countToken() will always return ZERO.
    you should use the String split(String regex) function, if you are using the jdsk 1.4 or higher.
public static void main(String[] args) {
    String str= new String("REMOVE_STR,01,6403,40,143,990,410,,,11,ATTN PAT COLEMAN,, ,,,N,,,,,,,,,,,NC,,,,,");
    String s[] = str.split(","); // require jdk 1.4
    // NOTE:   the String "a,,b"      - two commas return
    //    s[0] = "a"
    //    s[1] = "";    // empty string
    //    s[2] = "";    // empty string
    //    s[3] = "b";
    for (int i = 0; i < s.length; i++)
        System.out.println("Value of i = " + s);
System.out.println("Count is = " + (s.length - 1) );

Can some one help me with a small favor please, my program below reads from a file and Tokenize the string, the top layer of the string is OK however I want to write another method to tokenize off of the top layer it must be in a separate method because I want to call the method on a JSP page. Can someone view my code and help me with the other method please.
Thanks
KT

If you are trying to read tab delimited file and tokenize the contents, the code should be as below:
package dev;
import java.io.*;
import java.util.*;
public class RoundDetail2 {
     public String string_gameID;
     public String string_roundID;
     public String string_bet;
     public String string_win;
     public String string_roundDetail;
     public String string_date_time;
     public String tokenizer_topLayer;
     public String readDetail_topLayer;
     public static final String SUITS[] = {" ", "Clubs", "Hearts", "Spades", "Diamonds", "Joker", "FaceDown"};
     public static final String VALUES[] = {"Joker ","Ace", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Jack", "Queen", "King"};
     public static final String SuitVALUES[] = {" ","1","2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14"};
     String gameInfoText = "";
     public RoundDetail2() throws FileNotFoundException
          DataInputStream inFile = new DataInputStream(new BufferedInputStream(
                                        new FileInputStream("C:/apps/jakarta-tomcat-4.0.6/webapps/ROOT/WEB-INF/classes/dev/Data_452SY2.txt")));
          try
               while((readDetail_topLayer = inFile.readLine()) != null)
                    gameInfoText += readDetail_topLayer;
          }     catch(IOException e)
               System.out.println(e.getMessage());
     public void getGameInfo()
          StringTokenizer tokenizer_topLayer = new StringTokenizer(gameInfoText,"\t", false);
          while (tokenizer_topLayer.hasMoreTokens())
               string_gameID = tokenizer_topLayer.nextToken();
               string_roundID = tokenizer_topLayer.nextToken();
               System.out.println(string_gameID+" : "+string_roundID);
     public static void main(String[] args)
          try
               RoundDetail2 roundDetail = new RoundDetail2();
               roundDetail.getGameInfo();
          }catch(Exception e){}
Test if it works for you by running at command prompt.

Problem reading a string:Plz help

hi gurus
I am reading some files (in a loop written by some other program). I am reading them line by line and I tokenize each line by space using split function.
split(" ");
In resultant string array, somewhere I found NULL or nothing , for example, I print all tokens and it prints like this
?penguins/nns? // I print ?on both sides to check any spaces
?march/nnp?
?? // now here is problem.. both ? combined..nothing between them
I have checked the file.. this problem occurs where there are multiple spaces between tokens of a line...if I remove others and keep one space it works..
Now I want to implement a check in program i.e. where there is SPACE or NULL, I should not process it but It does not work
Please help

Thanks a Lot Sir
There is another problem that I am facing now..
I am using this statement
while ( (rec=dis.readLine() ) != null )to read a line from a file. What I have observed is that if there is a gap between two line then it stops executing file there and even does not go for further files..
Can you identify the problem or better solution
thanks

Problems with the Strings Urgent Help needed

I have a unique problem. I have to retrieve a particular value from a String. I tried using String tokeniser but in vain. I cannot use java.util.regex package to match the expressions as the version of java on the client m/c is 1.1.8 and they are not ready to upgrade the same.
The string From which I have is a very long one running into more than 100 lines which can vary from case to case all I know is to retrieve the value which is just in front of "TestValue" which occur only once in the String Can Anybody suggest a bettter alternative.
Thanx.

StringTokenize on TestValueHow would you suggest that was done?
As I understand it StringTokenizer tokens = new StringTokenizer(string, "TestValue"); would not tokenize on the string "TestValue" but on any of the characters 'T', 'e', 's', 't', 'V', 'a', 'l' or 'u'. This is a common java pitfall in my opinion due to bady named parameters (I feel it should be called "delims" not "delim") or in other people's opinion due to bad parameter type (should be a char[] not a string).
A clearer explanation of the problem would help.

String Tokenizer Helps

I need a little help
i am having trouble removing ALL the white space from my string using a tokenizer
here is my code so far:
    String str = "klj f a sklj fdaskldf"
    String deLimiters = " ";
    StringTokenizer tokens = new StringTokenizer(str, deLimiters);
    while(tokens.hasMoreTokens())
}how would i remove all the white space...and then display the string w/out white space???

StringTokenizer is a legacy class that is retained for compatibility reasons although its use is discouraged in new code. It is recommended that anyone seeking this functionality use the split method of String or the java.util.regex package instead.

It feels quite comfortable to use StringTokenizer over split. And in schools, and the way that I was tough at my time
instructors mainly used StringTokenizer.

String Tokens

Hi All
Iam getting input as
testdata = "ABC|123"
iam using
StringTokenizer = new StringTokenizer(testdata, "|");
This is giving me just the first value which is ABC.
I need values before and after the delimiter.
Any help is appreciated

Hi Thanks for response
String testdata = "ABC|123";
StringTokenizer tok = new StringTokenizer(testdata, "|");
while (tok.hasMoreTokens())
{ System.out.println(tok.nextToken());}
This works, but its working only for the first part of the string, i,e ABC, how can i get values after the token?
i mean 123, i hope iam making sense.
Thanks

Compilation Error while using string (Please help)

Hi,
I am using "Sun WorkShop Compiler C++ SPARC Version 5.000". Compiling code which contains a "string variable" throws the following error:
"/opt/WS5/SC5.0/include/CC/./new", line 32: Error: The prior declaration for ope
rator new(unsigned) has no exception specification.
"/opt/WS5/SC5.0/include/CC/./new", line 34: Error: The prior declaration for ope
rator delete(void*) has no exception specification.
"/opt/WS5/SC5.0/include/CC/./new", line 36: Error: The prior declaration for ope
rator new[](unsigned) has no exception specification.
"/opt/WS5/SC5.0/include/CC/./new", line 38: Error: The prior declaration for ope
rator delete[](void*) has no exception specification.
4 Error(s) detected.
The command used for compilation is :
/opt/WS5/bin/CC -compat=4 -I/opt/WS5/SC5.0/include/CC -features=%all try.cpp
Would help if I could get some comments on the above.
Thanks and Regards,
M Shetty

There is a requirement that I use the Workshop 5.0
compilere with option "-compat=4".
The program I am trying to compile contains:
#include <string>
int main()
string test = "aaa";
return 0;
There is no "string" in "-compat=4". You need to
do something like this:
// --- start test.cc ---
#include <rw/cstring.h>
int main()
RWCString test = "aaa";
return 0;
// --- end test.cc ---
CC -compat=4 -library=rwtools7 test.cc
