JSP declaration

The following question is there in one of the mock exam in jdiscuss. I have verified the output and the output is aaabbb.

<html>
<body>
<% String a = "aaa"; %>
<%! String a = "AAA"; %>
<%! String b = "BBB"; %>
<% String b = "bbb"; %>
<% out.println(a+b); %>
</body>
</html>

some one please explain me the logic behind this scenario.

<html>
<body>
<% String a = "aaa"; %>
<%! String a = "AAA"; %>
<% String b = "bbb"; %>
<%! String b = "BBB"; %>
<% out.println(a+b); %>
</body>
</html>

The best way to figure out what is going on is to have a look at the Java servlet that the container will create on behalf of your JSP page. This is perhaps the most instructive thing you can do to find out why JSPs behave the way that they do.

For Tomcat, the Java files are written to the folder hierarchy at $CATALINA_HOME/work.
