seems to work fine I fixed this problem by reinstalling the JRE, JDK and created a completely new installation of eclipse. Apparently the old eclipse was still linked to some leftovers from a Java 7 JDK.

hop of those help? Best Practices
Ideally, one shouldn't have any <% // scriptlet %> blocks in JSPs any more.
code :
 <jsp:useBean id="user" class="foo.User" /> <!-- scope="page" by default -->
<% // in Title.jsp
  request.setAttribute ("user", new User());
%>

<% // in Header.jsp
  User user = request.getAttribute ("user");
  user.setName ("John Doe");
%>

I think the issue was by ths following , the variables "alen" and "blen" you declared in main() are method-local, that means they are not accessible from printMatrix() method. Make them fields instead by writing:
code :
private int alen;
private int blen;
(java) <name> cannot be resolved to a variable

(java) <name> cannot be resolved to a variable

Does that help The problem is you are missing the variable name when instancing the game:
code :
public class GameLauncher{
    public static void main(String[] args){
        GuessGame game= new GuessGame(); //game is the variable
        game.startGame();
    }
}

like below fixes the issue You are trying to assign result to the value of searchedFor in your search method, through invoking equals, which actually return boolean if x equals argument.
Use = to assign instead.
