For example, Java 8 was released in 2014 which completely changed how Java is written and now within the last 6 months, we have two major Java releases in the form of Java 14 and Java 15. But the good thing is that the core of Java is still the same and all its releases are backward compatible. You know when you sign up to an online learning platform that is video based and you just keep thinking ooh it’s really not as good as @pluralsight and gee Pluralsight does this so much better. One reason I love @pluralsight training is how they curate similar courses on a subject into a learning path. The diversity of content delivery & repetition of salient points by the SMEs helps to make the learning process efficient and memorable.

Developers have defined various configurations of Java in order to fulfill the requirements of multiple platforms such as Java EE for Enterprise Applications and Java ME for Mobile Applications.

Java Io

Java requires the source code of your program to be compiled first. It gets converted to either machine-specific code or a byte code that is understood by some run-time engine or a java virtual machine. This is achieved by most Java compilers by compiling the Java language code halfway – simplified machine instructions specific to the Java platform. The code is then run on a virtual machine , a program written in native code on the host hardware that interprets and executes generic Java bytecode. Note that, although there is an explicit compiling stage, at some point, the Java bytecode is interpreted or converted to native machine code by the JIT compiler. There’s lots to learn, but a Java course or tutorial on edX can help you master these concepts.

Java SE Lessons

Java SE provides high-level classes used for networking, security, database access, GUI development, and XML parsing. RMI- RMI stands for Remote Method Invocation enables the programmer to create distributed Java technology-based to Java technology-based application. RMI uses object serialization to marshal and unmarshal parameters and does not shorten types. Packages are a feature of the Java programming language that help you to organize and structure your classes and their relationships to one another. Interfaces and Inheritance describes interfaces—what they are, why you would want to write one, and how to write one. This section also describes the way in which you can derive one class from another. That is, how a subclass can inherit fields and methods from a superclass.

This feature of Java Code Geeks makes it different from other online Java tutorials. You can learn about different variants of Java under this platform such as core Java, desktop Java, and enterprise Java. Java is a general-purpose programming language that’s used in all industries for almost any type of application.

One characteristic, platform independence, means that programs written in the Java language must run similarly on any supported hardware/operating-system platform. One should be able to write a program once, compile it once, and run it anywhere. Sun’s revenue from Java was generated by the selling of licenses for specialized products such as the Java Enterprise System.

The program or other objects can reference an object by holding a reference to it (which, from a low-level point of view, is its address on the heap). When no references to an object remain, the Java garbage collector automatically deletes the unreachable object, freeing memory and preventing a memory leak. Memory leaks may still occur if a programmer’s code holds a reference to an object that is no longer needed—in other words, they can still occur but at higher conceptual levels.
