Question

I want to use the lang variable in my code, and give the value in the if command.
Is the below code possible in .jsp page ?

<%
  String language = "EN";
  EN lang;
  if (language.equals("EN")){
    lang = new EN();
  }
  else if (language.equals("FR")){
    lang = new FR();
  }
%>
// html ...
<% out.print(lang.variable1); %>

i got this error :

incompatible types; found: mypackage.FR, required: mypackage.EN

code please ?

Answer 1

Your code should look something like this:

interface Lang {

}

class EN implements Lang {

}

class FR implements Lang {

}

<%
  String language = "EN";
  Lang lang;
  if (language.equals("EN")){
    lang = new EN();
  }
  else if (language.equals("FR")){
    lang = new FR();
  }
%>
