ASCII values table

                          

ASCII stands for American Standard Code for Information Interchange. Computers can only understand numbers, so an ASCII code is the numerical representation of a character such as @, #, $, and so on. ASCII was developed when non- printing characters were rarely used. 

In the  example given below we have include the description of the some non- printing characters.

 

The code of the program is given below:

 

 

<%@ page session="false" %>
<html>
<body>
<center>
<h1>Table of a ASCII value</h1>
<table border="1" cellpadding="0" cellspacing="0" bgcolor="#FDFFE6">
<%
   StringBuffer sb = new StringBuffer();
   sb.append("<tr>");
   sb.append("<th width=\"50\">&nbsp;</th>");
   for (int col = 0; col < 16; col++) {
      sb.append("<th>");
      sb.append(Integer.toHexString(col));
      sb.append("</th>");
   }
   sb.append("</tr>");
   for (int row = 0; row < 16; row++) {
      sb.append("<tr>");
      sb.append("<th>");
      sb.append(Integer.toHexString(row));
      sb.append("</th>");
      for (int col = 0; col < 16; col++) {
         char c = (char)(row * 16 + col);
         sb.append("<td width=\"32\" align=\"center\">");
         sb.append(c);
         sb.append("</td>");
      }
      sb.append("</tr>");
   }
   out.println(sb);
%>
</table>
</center>
</body>
</html>
