Java Tutorial #29 - Abstract Class and Abstract Methods in Java Programming • In this video by Programming for Beginners we will learn Abstract Class and Abstract Methods in Java Programming, using Java Tutorial videos. • The abstract class in Java cannot be instantiated (we cannot create objects of abstract classes). We use the abstract keyword to declare an abstract class. • Example: • abstract class Language { • // fields and methods • } • // try to create an object Language • // throws an error • Language obj = new Language(); • An abstract class can have both the regular methods and abstract methods. For example, • abstract class Language { • // abstract method • abstract void method1(); • // regular method • void method2() { • System.out.println( This is regular method ); • } • } • Java Abstract Method: • A method that doesn't have its body is known as an abstract method. We use the same abstract keyword to create abstract methods. For example, • abstract void display(); • If a class contains an abstract method, then the class should be declared abstract. Otherwise, it will generate an error. For example, • // error • // class should be abstract • class Language { • // abstract method • abstract void method1(); • } • ========== • We can learn Java Programming language to make web applications or mobile applications for android phones and several other applications for windows, Mac OS and Unix operating systems. Also we can make android applications using Java programming. The concepts covered will be related to basic java and core java that will help you in your next interview questions. You can use any version of Java but all concepts will be same for all java versions. I will be using Java SE 8. • Java is a high-level programming language. Java runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX. • Java is a MUST for students and working professionals to become a great Software Engineer specially when they are working in Software Development Domain. • Java Tutorial Playlist: • • Java Tutorial • Java JDK: • https://www.oracle.com/java/technolog... • Eclipse IDE: • https://www.eclipse.org/downloads/ • YouTube Gears: • Microphone: https://amzn.to/3iIk5K3 • Mouse: https://amzn.to/35irmNF • Laptop: https://amzn.to/3iG0jyD • #Java #Tutorial #Programming • ============================ • LIKE | SHARE | COMMENT | SUBSCRIBE • Thanks for watching :)
