Why is this StringTokenizer not tokenizing properly following the second time?

Question

I want to parse the following using StringTokenizer for every string matching agent>. I tried it using the code like this. Where I am going wrong?

StringTokenizer stringtokenizer=new StringTokenize(hari,"agent>");

while(stringtokenizer.hasMoreTokens())
{
    String token = stringtokenizer.nextToken();
    System.out.println("output ="+token);
}

It is tokenizing properly only for two times and then it is responding irregularly... I mean for first time

output =ACT-USER::USER_1:AU01::******;


   SIMULATOR 09-11-17 09:37:01
M  AU01 COMPLD
;

Second time:

output =RTRV-HDR:::RH01;


   SIMULATOR 09-11-17 09:37:01
M  RH01 COMPLD
;

Third time:

output =RTRV-EQPT::ALL:RE01;


   SIMULATOR 09-11-17 09:37:02
M  RE01 DENY
   SROF
   /*S
output =us, R
output =qu
output =s
output =d Op
output =r
output =io
output = F
output =il
output =d*/
;


ACT-USER::USER_1:AU01::******;


   SIMULATOR 09-11-17 09:37:01

Please let me know where i am going wrong.

You didn't read the API. StringTokenizer does not accept a string as a single delimiter. It accepts a string where each character in the string is treated as a one character delimiter.

Try using String.split(...);

Try this,

int idx=0; int tokenCount;
String words[]=new String [500];
String message=//String to be tokenize;
StringTokenizer st=new StringTokenizer(message);
tokenCount=st.countTokens();
System.out.println("Number of tokens = " + tokenCount);
while (st.hasMoreTokens()) // is there stuff to get?
    {words[idx]=st.nextToken(); idx++;}
for (idx=0;idx<tokenCount; idx++)
    { if(words[idx].equals("agent>");//do something

}

Why is this StringTokenizer not tokenizing properly following the second time?
