An abstract class can have instance methods that implement a default behavior. An Interface can only declare constants and instance methods, but cannot implement default behavior and all methods are implicitly abstract. An interface has all public members and no implementation. An abstract class is a class which may have the usual flavors of class members (private, protected, etc.), but has some abstract methods.

Overriding is a method with the same name and arguments as in a parent, whereas overloading is the same method name but different arguments

CDATA - (Unparsed) Character Data

To send the characters that can not be specified in a URL should be converted into their equivalent hex encoding. To perform this task the methods encodeURI() and decodeURI() are used.

For example, the following code snippet performs the encoding of URL:

<script type="text/javascript">

          var uri = https://www.mysite.com/city?=Banglore; // original URI

          var ncodeuri=encodeURI(uri);

          document.write("<br />ncodeuri”);

          var dcodeuri = decodeURI(ncodeuri); 

          document.write(“<br>/>dcodeuri”);

</script>

These are accessibility modifiers. Private is the most restrictive, while public is the least restrictive. There is no real difference between protected and the default type (also known as package protected) within the context of the same package, however the protected keyword allows visibility to a derived class in a different package.
