If you are really interested to learn Java then you are at the right place because here in this article you will find an overview of Java basics over here. So here it is a provision for you for as a self guided version. There would be plenty of code examples as you move ahead with this article.
This first article presents the Java system and describes the distinction between its three editions: Java SE, Java EE, and Java ME. You’ll also learn about the part of the Java Virtual Machine (JVM) in implementing Java applications.
A general purpose and an object oriented language that looks a lot like C and C++ but is easier to use and allows you to create more programs.
A network-savvy language: TCP/IP network protocols like HTTP and FTP and it can be easily coped up with extensive network library of Java. And they can access the URLs in an easy way as if its is a normal file.
Java is a robust language: Java programs must work because they are used in both client and mission-critical programs, different from Blu-ray players to vehicle-navigation or air-control techniques. Language functions that help make Java effective statements, duplicate type confirming at compile time and play-back, real arrays with computerized extensive variety confirming, and the omission of pointers.
Java is a convenient language: Structure neutrality leads to mobility. However, there is more to Java’s mobility than platform-independent bytecode guidelines. Consider that integer type sizes must not differ. For example, the 32-bit integer type must always be finalized and take up 32 bits, regardless of where the 32-bit integer is prepared (e.g., a system with 16-bit signs up, a system with 32-bit signs up, or a system with 64-bit registers). Java’s collections also play a role to portability.
Java is a multithreaded language: To improve the efficiency of programs that must achieve several projects at once, it facilitates the idea of threaded efficiency. For example, a program that controls a Graphical User Interface (GUI) while patiently awaiting feedback from a system relationship uses another line to perform the delay instead of using the standard GUI line for both projects. This keeps the GUI responsive.
Java is a secure terminology: Java applications are used in networked/distributed surroundings. Because Java applications can move to and perform on a network’s various systems, it’s important to protect these systems from harmful code that might spread malware, grab bank card information, or perform other harmful functions. Java terminology functions that support sturdiness (like the omission of pointers) work with protection measures such as the Java sandbox protection model and public-key security.
Java is a high-performance language: Presentation results in a level of efficiency that is usually more than adequate. For very high-performance application circumstances Java uses just-in-time collection, which examines considered bytecode training series and gathers frequently considered training series to platform-specific guidelines. Following efforts to understand these bytecode training series result in the performance of equivalent platform- specific guidelines, leading to an efficiency boost.
Java is an object-oriented Programming (OOP’s): Java’s object-oriented concentrate allows developers work on adjusting it to resolve an issue, rather than pushing us to control the issue to meet terminology constraints. This is different from an organized language like C. For example, whereas it allows you concentrate on bank consideration objects, C requires you to think independently about bank consideration state (such a balance) and actions (such as deposit and withdrawal).
Sun fixed the submission issue by considering Java into three main versions. These gradually became known as Java SE, Java EE, and Java ME:
Java System, Standard Edition (Java SE) is the Java platform for creating client-side applications, which run on desktop computers, and applets, which run in Internet Explorer.
