Hi im tryin to extract int values from a StringBuffer looking something like this for instance:
"|5|56|789|4|21"
would this code work?
-----------------------------------------------------------------
//Buff is the StringBuffer where the string is stored

int start=0;
int end=0;
int invalues[]=new int[5];
for(int i=0; i<invalues.length; i++) {
start=buff.indexOf("|",start);
end=buff.indexOf("|",start);
String mini=buff.substring((start+1),end);
int convInt= new Integer(mini).intValue();
invalues[i]=convInt;

}

Why dont you just use StringTokenizer???

because i dont know how to use it and im in a hurry!
however my question was if the code i wrote would work properly and i would apriciate if someone would correct it

First, why are you askin if this code would work? Just test it.

Well, I just played a littlebit with your code and thats my result

        StringBuffer buff = new StringBuffer().append("|5|56|789|4|21|");
int invalues[]=new int[5];
int start=0;
int end=0;
for(int i=0; i<invalues.length; i++)
{
    start = buff.indexOf("|",end);
    end = buff.indexOf("|",start+1);
    String mini = buff.substring((start+1),end);
    int convInt = Integer.parseInt(mini);
    invalues[i]=convInt;
} 

Note that I have added an | at the end of the buffer to prevent a -1 for the last value of end.
I guess you ar using Java 1.4 because you are using StringBuffer.indexOf so why don't you String.split ?

Have a nice day,

heh , i was in a hurry too , for something similar ...
it took about 5 minutes through a book , thanks a lot pixel

O.k., you said you're in a hurry, but if you instead want to use StringTokenizer, try this:

StringTokenizer tok = new StringTokenizer(buff, "|");
int i=0;
int intvalues[] = new int[5];

while(tok.hasMoreTokens() {
  intvalues[i]=Integer.parseInt(tok.nextToken());
  i++;
}
