How to set up Java Development Kit 8 - Java SKD 8 Oracle

The video tutorial teaching all the necessary set to set up your Java development environment. Java is leading the world from web applications to smart phone devices like android. Java is everywhere. The quicker you shift to learn this wonderful language the better equip you will be ahead of the game. Java is a strongly type language which means that all variables type must be declared first before you. When you use the Java compiler to convert your java file into a JVM (Java Virtual Machine) executable the compiler will turn your code into bytecode. Java does not support pointers like very popular languages like C and C++. This is because of security issue with accessing the memory location which can lead to exploits. Even worst can bypass the firewall is code memory location is known. In the tutorial I begin by referencing the Java website to set up the base. Then I refer to the source development kit to start creating and compiling your own code. The compiler makes use of the javac “FILENAME.java” command to run the compiler. If you need to know the current java version running on your machine use the java -version command inside of command prompt. Once we have installed the basic’s in the video then I go ahead and show you an example program that we can write and run. I used the text editor of notepad ++ to accomplish this task. I have placed a download link below if you would like to use it as well.
