急啊，关于string类的比较问题

DEBUG调一下看看ryxm和cryxm的值就知道了int ryid=new Integer(request.getprameter("ryid"));
String ryxm=new String(request.getprameter("ryxm")).getbytes("iso-8509-1");
out.println("ryxm:"+ryxm);//add
int count=0;
int cryid;
String cryxm;
    while(rs.next())
    {
       cryid=rs.getInt(1);
       cryxm=rs.getString(2);
       out.println("cryxm:"+cryxm+"<br>");//add
       if(ryid==cryid && ryxm.equals(cryxm))  count=1;
     }
