The frame is a top-level window with a title and a border, created through JFrame component of Swing. Please refer GUI Programming and Access Specifier Class 12 Notes for more information.
6. Inheritance Class 12 Notes CBSE Notes for Inheritance Class 12 Notes Inheritance is an act of deriving a new class from an existing one. Inheritance can be defined as the process where one object acquires the properties of another. With the use of inheritance, the information is made manageable in a hierarchical order. Basics of inheritance When a class is defined in the normal class declaration, it is called a base class. A class at the top of the hierarchy is the base class and the other class is the derived class. That is a child class o one parent can itself be the parent of another derived class. Furthermore, multiple classes can be derived from a single parent. Please refer Inheritance Class 12 Notes for more information.
7. Accessing MySQL Database using ODBC/JDBC Class12 Notes CBSE Notes for Accessing MySQL Database Using ODBC/JDBC Class 12 Notes Prerequisites for connecting to MYSQL from java MYSQL provides connectivity for client application developed in the java programming language via a JDBC driver known as MYSQL Connector/J. Connection: A connection is a session between the application program and the database. To do anything with a database, one must have a connection object.

8. Web Application Development Class 12 Notes CBSE Notes for Web Application Development Class 12 Notes World Wide Web is an example of an information protocol/service that can be used to send and receive information over the internet. It supports: Multimedia Information HyperText Information Graphical User Interface: The World Wide Web is an example of an information protocol/service that works using a Client/Server software design. A service that uses Client/Server design requires two pieces of software to work: Client software (e.g. Web Browser) to request information, and Server software(Web server) to answer requests and provide their information. Most Web applications are designed this way. Please refer Web Application Development Class 12 Notes for more information.
9. HTML and XML Class 12 Notes CBSE Notes for HTML and XML Class 12 Notes The World Wide Web (or simply the Web or WWW) is a system of sharing interlinked hypertext documents over the internet. These documents are stored on webservers on the internet and contain text, images, videos, and other multimedia. These documents also contain hyperlinks to navigate among them. HTML (HyperText Markup Language) is the basic language which is used to create Hypertext documents. In this lesson, we are going to learn how to create hypertext documents using HTML. It is a markup language. A markup language is a set of rules that defines the structure and format of text while presenting text. XML stands for eXtensible Markup Language. XML is designed to transport, store and describe data. Whereas HTML was designed to display data. XML tags are not predefined. We must define your own tags in XML. An XML document that follows all grammar rules is a well formed document. Please refer HTML and XML Class 12 Notes for more information.
