Do I have one instance of a method

Question

I create a class and define a staic method
then I call it in JSP
<%
Myclass class1=new Myclass();
class1.StaticMethod();
%>
When a lot of people visit my JSP page
I have only one instance of StaticMethod()
or many of it?

Answer 1

// Myclass .java
public class Myclass {
static Object testObj=null
static void StaticMethod(){
if(testObj==null){
System.out.println("=null");
testObj= new String("123");
else{
System.out.println("not null");
then I call it in JSP
<%
Myclass .StaticMethod();
%>
So Only first time Who visit it print "=null";
Other visitor only received it print "not null";
Is it mean all Visitor share one
StaticMethod() ?
