I am fairly new to JSP , i learned that to create a variable you say this

<%String abc="1"; %>

If i want to change to value of abc I used this 

<%= abc = "2" %> //Is this the right way??

But this value is shown on my JSP page how do I make it not show in my jsp page.

The short answer to your question is remove the =. The <%= %> evaluates and prints the contents. Anything between <% %> is just standard java code. So, you want

<% String abc = "1"; %>
....some stuff....
<% abc = "2"; %>

Change 

<%= abc = "2"; %>

To

<% abc = "2"; %>

Delete the "="

A JSP expression is used to insert Java values directly into the output. It has the following form:

 &lt;%= Java Expression %&gt;

Using only one = operator to change value of abc. http://faculty.cs.wwu.edu/meehan/Programming_Language_Projects/JSP/
