How to write methods inside JSP and call them?

Following is my jsp code. I'm new to JSP. I get the error shown after the code

<body>
<%!
    public ArrayList<ArrayList<Leg>> trip;
    public void routeManager(){
        Location stLoc = new Location(60.2040521,24.96185113,"1023");
        Location endLoc = new Location(60.17936316, 24.92282214 ,"1130");
        RouteRetriever hrr = new RouteRetriever();
        trip = hrr.getRoutes(stLoc, endLoc, false);
    }
%>
<%  routeManager();
    System.out.println("Im here AA");%>
<%= out.println("Hello World:"+hrr.size()) %>
<p>Booooooooooooo!</p>
</body>

Error:

An error occurred at line: 30 in the jsp file: /index.jsp
The method print(boolean) in the type JspWriter is not applicable for the arguments (void)

I think you should change 

<%= out.println("Hello World:"+hrr.size()) %>

to (just output)

<%= "Hello World:"+trip.size() %>

or if you want to use println (change <%= to <%):

<% out.println("Hello World:"+hrr.size()); %>

<%=%> and out.println does not go together.

Change

To

<% out.println("Hello World:"+hrr.size()); %>

<%=%> is a short hand converted into out.write when Jsp page is compiled
