String sNumber = request.getParameter("sNumber");
String oper = request.getParameter("oper");
String result="";
if(oper!=null) {
if(oper.equalsIgnoreCase("+"))
result=(Integer.parseInt(fNumber) + Integer.parseInt(sNumber))+"";
else if(oper.equalsIgnoreCase("-"))
result=(Integer.parseInt(fNumber) - Integer.parseInt(sNumber))+"";
else if(oper.equalsIgnoreCase("*"))
result=(Integer.parseInt(fNumber) * Integer.parseInt(sNumber))+"";
else if(oper.equalsIgnoreCase("/"))
result=(Integer.parseInt(fNumber) / Integer.parseInt(sNumber))+"";
else
result="NaN";
}
