WHAT IS UTF-8 ?

UTF-8 :   UCS Transformation Format — 8-bit

Unicode is a character set supported across many commonly used software applications and operating systems.

Operating systems that support Unicode include Solaris Operating Environment, Linux, Microsoft Windows 2000, and Apple’s Mac OS X.

Applications that support Unicode are often capable of displaying multiple languages and scripts within the same document.

In a multilingual office or business setting, Unicode’s importance as a universal character set cannot be overlooked.

Unicode is the only practical character set option for applications that support multilingual documents.

An encoding is the mapping of Unicode code points to a stream of storable code units or octets.

What is URLEncoding in Java ?

Utility class for HTML form encoding. This class contains static methods for converting a String to the application/x-www-form-urlencoded MIME format. For more information about HTML form encoding, consult the HTML specification.

When encoding a String, the following rules apply:

• The alphanumeric characters "a" through "z", "A" through "Z" and "0" through "9" remain the same.
• The special characters ".", "-", "*", and "_" remain the same.
• The space character " " is converted into a plus sign "+".
• All other characters are unsafe and are first converted into one or more bytes using some encoding scheme. Then each byte is represented by the 3-character string "%xy", where xy is the two-digit hexadecimal representation of the byte. The recommended encoding scheme to use is UTF-8. However, for compatibility reasons, if an encoding is not specified, then the default encoding of the platform is used.

jQuery function , Selectors, Fade effect.

jQuery function

• You use this to select elements from an HTML page to manipulate.
• The $ shortcut means you don't have to type “jQuery" over and over.
• The jQuery function can handle selectors, straight HTML, and even JavaScript objects.

Selectors

• jQuery selects elements the same way CSS does: with selectors.
• Just about any kind of HTML element is fair game for a jQuery selector.

Fade effect

• Once you've selected an element, you can fade it in a variety of ways, using FadeIn, FadeOut, FadeTo, and FadeToggle.
• You can fade in all kinds of elements, from text to images and more.
• Control the speed of your fade effect by putting a time (in milliseconds) value inside the parentheses at the end of the statement.

Convert JAVA DATE to MS SQL datetime format

SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");

Date javaDate=new Date();

System.out.println("Java Date : "+javaDate);

String msSqlDate=sdf.format(javaDate).trim();

System.out.println("Ms Sql Date : "+msSqlDate.replace(" ","T"));

insert into DATA (CREATED) values (convert(datetime,'"+msSqlDate+"'));
