Using Abstract Windowing Toolkit (AWT) In Applications
A well laid out user interface is an effective means of making applications user-friendly. It is typically used by organizations for accepting orders from customers, getting customer’s feedback on a product, for conducting a market survey on the latest trends in economy.
A well laid out user interface is an effective means of making applications user-friendly. It is typically used by organizations for accepting orders from customers, getting customer’s feedback on a product, for conducting a market survey on the latest trends in economy. It finds its use even in stock market, political polling, conducting a test over the Internet using forms, the list seems never ending. User interfaces are of two types, Character User Interface (CUI) and Graphical User Interface (GUI).
Using CUI, you can interact with the system by keying in commands. Classic example of CUI is MS-DOS, the only disadvantage is that you have to remember all the commands and syntax. Today, GUI has been accepted as a worldwide standard for software applications. Since they provide a “picture-oriented” or “graphical” approach for interacting with the system. They are not only easy to use by also to learn. You don’t have to remember long lines of syntax, because most of the commands are executed by a simple mouse click. Microsoft’s Windows family of products is an example of an operating system that supports GUI.
In the present world with the popularity of Apple’s Macintosh and Microsoft Windows operating system, most of today’s computer users expect their software to feature a graphical user interface and things they can control with a mouse. Typically GUI includes windows, menu, buttons, scroll bars, icon images and wizards. Almost all Operating systems today provide GUI plus add their own elements. An integral part of any programming language is the ability to accept data from a use. The user has to be prompted for data entry. To simplify user interaction and make data entry easier, you can use controls. Controls are components like buttons and text boxes that can be added to containers like frame, panels and applets. The Java AWT package provides an integrated set of classes to manage user interface components
