Am I missing something, String function...

Question

OK... I have a method in my class that returns a string. Maybe I should be doing it with a StringBuffer, BUT... I cannot see why this does not work.
When running in the main() method (for testing) it works fine. When called as an object, and the method is called, it's output on my machine indicates that even though I am setting the first int to 0, it is starting at 32778...
Here is the offending code, any luck?
public String replace(String ko, String kt, String lg)
String sk_y = "<"+ko+">";
String ek_y = "</"+ko+">";
String sk_r ="<"+kt+">";
String ek_r ="</"+kt+">";
String nw = "";String sso="";
try{
int pot=0; int mk=0;
while (true)
System.out.println("+xLS.replace:start:"+pot);
mk = lg.indexOf(sk_y,pot);
nw=nw+lg.substring(pot,mk);
nw=nw+sk_r;
pot=mk+sk_y.length();
mk=lg.indexOf(ek_y,pot);
nw=nw+lg.substring(pot,mk);
nw=nw+ek_r;
pot=mk+ek_r.length();
System.out.println("+xLS.replace:end:"+pot+"\nnw=="+nw);
sso=nw;
catch(Exception e){/*done*/
pot=0;mk=0;
return sso;
Thanks,

Answer 1

the problem is the scope of your variables.... or not :^)
I�ve run your coude here and everything looks OK.
I used this command line:
replace("f", "b", "<f>bla </f>");
