Java is a general purpose and object-oriented programming language developed by Sun Microsystems to operate and empower applications to operate, write once, run everywhere (ASYNC) performance on the network and enable developers to write flexible, efficient and secure code with the help of the tools and language features. Java is written with C and some other low-level libraries of C++ and runs on the Linux platform. It can also be used on windows server for the use of back-office applications. Java also runs on the desktops of desktop computers and laptops. Java applets are used for the graphical user interface elements of Java applications. In this java tutorial for beginners, we'll see the different aspects of Java including the Java language itself, the various components of java, the various Java development options and their respective strengths and weaknesses, and Java's significant advantages over the other systems. Java memory management is quite efficient when compared with the others because the garbage collector keeps the program from being stalled waiting for a reference to be valid. The in-order-to mechanism of Java handles exception management fairly well. This means that programmers don't need to resort to hand coding the error condition into the application code, which is quite tedious. The in-order-to technique is again applicable if the programmer is writing Java for the server. The main topics covered in Java Tutorial include - basic types and functions of Java, types of objects, primitive types and constructors, variable types and access control, dynamic typing and dynamic binding, path expressions and overloaded functions, standard library, date and time, networking basics, package management, exception and catch statement, Strings and characters, introspection, interfaces, and object orientation. Apart from these basic topics, the Java Tutorial also provides information about the various object-oriented features. The different kinds of Java classes discussed here include - instance, interface, class, concrete class, abstract class, private instance, public instance, inherited instance, protected instance, abstract class, static final, inherited final, shared instance, and trait. It should be mentioned here that all these classes have different features and are used differently in Java applications. Java's object-oriented architecture is based on the idea of the model, so that it can be reused at run anytime without any complications. A model in this architecture can be anything - an interface or an abstract class. However, the most popular examples are interfaces where in an interface can be anything from a Text class to a Java servlet. The Java Tutorial also goes through various examples of Java programs, which are quite useful for beginners. Most of these Java examples involve simple programs that allow the users to grasp the working of Java easily. Java's famous libraries make java for each loop function programming very easy. With these excellent resources, you can find just about everything you need in building a good website. Even the most advanced developers will find it easy to use some of the tools available in the popular libraries. This Java Tutorial also goes through the essential features of Java such as how to create a main class, where and how to create various types of objects, the equals and satisfies methods, how to create closures, Java's support for Java Beans and the reflection facilities. It also explains about Java's memory management system so that you know what are the best practices to avoid memory issues in Java program. The Java Tutorial concludes with the most important thing that should be understood by the users - how to use the standard Java library. Here, the Java Programmers Guide helps the users understand the difference between the normal library and the specialised one and the functions they can perform. It also describes about the different type of structures available in the Java memory and the different ways to utilise these structures for your Java Program. Most importantly, the Java Tutorial stresses the importance of reading the Java Manual because it provides full detail on the subject. A Java Tutorial can only teach you a part of the journey; you must learn from experience and with some practical applications.
