Hi Praveen
Oops...It still does not work : (
StringBuffer retStr = new StringBuffer("");
int iret;
boolean isBot=false;
isBot = isBotHead(iret,retStr);
// I want get iret = 2000 & retStr = "FLYING" now
// but ...
protected boolean isBotHead(int iret,StringBuffer retStr){
iret = 2000;
retStr = new StringBuffer("FLYING");
return true;
}
