Use jstl

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>   
<c:set var="ID" value="5"/>   
<c:set var="Name" value="Riyana"/>   
<td align="right">Name</td>    
<td><input name="name" value="${Name}" size="50" type="text"></td>

<td align="right">Name</td> 
    <td><input name="name" value='<%=Name%>' size="50" type="text">
</td>

Use single quotes in the value of the input text, like value='<%=Name%>' instead of double quotes like value="<%=Name%>"

I would strongly suggest you not to use Java code in jsp, its bad MVC design.

You should pass these variable from servlet and on jsp use jstl to access variables

how ever for your code solution is here.

<%!  

 int ID=5; 
 String Name="Riyana"; 

%>

<input name="name" value="<%=Name%>" size="50" type="text">

  <%!   int ID=5; String Name="Riyana"; 
%>

value="<%=Name%>"

Please use <%! %> for variable initialisation.

  <td align="right">Name</td> 
  <td><input name="name" value="<%=Name%>" size="50" type="text">
  </td>       
</tr>

Do not use scriptlets, try the taglibs instead.
