Java is basically an object-oriented programming language or better known as object-oriented programming sequence which is abbreviated as OOPS. By using such a programming language like Java, the user can reuse or extend the functionalities and capabilities of an existing class in a new class if both the classes have similarities amongst themselves. The class can, however, inherit the features of a related class and add new features, as per the requirement.
Implementing the Inheritance Of Java
As stated above the inheritance of the features of a subsequent class and the addition of new features into a class, allows the sharing and reuse of codes. This, in turn, helps in making the code of an application more organized and efficient by reducing redundancy. The inheritance of Java can be understood in details with the following instance.
Coding is extremely important to serve the different functionalities of a jumble word game. The levels in the game are based upon the maximum number of attempts that can be availed by a player, are implemented by this coding process. With each subsequent level more sets of functionalities like timer and score are added to the game. The timer specifies the limit within which the player will be required to identify the correct word. As the game progresses the value of the timer will be decremented. If the player is unable to identify the correct word in the time specified by the timer, the game will terminate. Furthermore, with the change in the complexity level of the game, there will be a variation in how the player scores are computed.
The role of coding comes into play when the game functionality is required to be enhanced. One easy way will be to recode the entire application, but this will introduce redundancy in the codes and will also consume a large amount of time. This might be due to the reason that some of the required sets of functionality are common to all levels such as displaying the menu and instructions. Hence the smartest way will be to reuse the existing code, by adding the new desired functionality to the existing functionalities. For this, the inheritance feature of Java can be implemented through interfaces and classes. In inheritance, the class that inherits the data members and methods from another class is known as the subclass or derived class. The class from which the subclass inherits the features is known as the superclass or base class. JAVA ONLINE TEST is administered to test how capable the applicant is, in terms of coding and its use.
What is a User Interface?
An interface is a layer between a user and an application. It helps the user to interact with the application. The application can contain the Graphical User Interface (GUI) which consists of images, text and graphics.
To create the windows based applications, one needs to understand the features of the graphical user interface for creating an interactive and effective interface. For this reason, Java provides the Swing toolkit and Abstract Window Toolkit. The swing toolkit and AWT contain the various classes and interfaces to create the Graphical User Interface based applications.
