try like:

<%
      String a = session.getAttribute("myvalue")==null?"":session.getAttribute("myvalue").toString();
      String b = a.length() > 1?  a.substring(0,1).toUpperCase() + a.substring(1).toLowerCase() : "";
      
      out.println(b);
%>

Hi huzefaq,

Using JSTL (can be obtained from jakarta.apache.org) its very easy for string operations on jsp pages.

chk this link

http://jakarta.apache.org/taglibs/doc/string-doc/index.html


capitalize  =>       Capitalize a String. The first character is converted to TitleCase.

from my example above, like:

String b = a.length() > 1?  a.substring(0,1).toUpperCase() + a.substring(1).toLowerCase() : "";

should be as:

String b = a.length() > 1?  a.substring(0,1).toUpperCase() + a.substring(1).toLowerCase() : a.toUpperCase();

Hi,
There are two posibilities.
1) you want only first word to be capitalized

static void printCapitalized( String inputWord) {

String firstLetter = inputWord.substring(0,1);  // Get first letter
String remainder   = inputWord.substring(1);    // Get remainder of word.
String capitalized = firstLetter.toUpperCase() + remainder.toLowerCase();

System.out.println(capitalized);

}

2) each  word of string to be capitalized

  static void printCapitalized( String str ) {
          char ch;       // One of the characters in str.
          char prevCh;   // The character that comes before ch in the string.
          int i;         // A position in str, from 0 to str.length()-1.
          prevCh = '.';  // Prime the loop with any non-letter character.
          for ( i = 0;  i < str.length();  i++ ) {
             ch = str.charAt(i);
             if ( Character.isLetter(ch)  &&  ! Character.isLetter(prevCh) )
                 System.out.print( Character.toUpperCase(ch) );
             else
                 System.out.print( ch );
             prevCh = ch;
          }
          System.out.println();
       }

try:

<%
     String display = session.getAttribute("value")==null?"":session.getAttribute("value").toString();
     if (Character.isLowerCase(display.charAt(0)))
         display = display.substring(0,1).toUpperCase() + display.substring(1,display.length());
%>
