Getting Started With Java Programming For Entrepreneurs


Java is a commonly used programming language that serves as a template for creating web-based or offline applications. It is incredibly versatile in its functions. This entails that there is somewhat of a learning curve for getting started with it. If you are an entrepreneur looking to profit from the development of a useful web application, refer to this step-by-step guide on getting started with Java programming.

Download the Java Development Kit

Before you can get started developing a program for your business, you need to set up an environment for development. This means downloading and installing a Java development kit. Doing so is as easy as going to their main website ( and choosing the Java Development Kit. Installation requires no extra steps. You may want to switch over to a third-party development program later on, but the JDK should suffice for now as you are only beginning to enter Java programming.

Set Up Environment Variables

Environment variables are basically commands that affect the way certain processes behave on a computer. You want to set your development kit up to know where your assets are going to be, so the first variables you need to set are the locations of your Java development kit and Java home directory. For Windows users, this is as simple as right-clicking My Computer, clicking the Advanced tab, and going to Environment Variables. Once this step is done, you can move on to actual development.

Create Your First Program

Now, we can start developing real Java programs. A common practice in starting Java programming is creating a program called “Hello World!” All you need to do is open a simple text editor and enter these commands: class myfirstjavaprog


public static void main(String args[])


System.out.println(“Hello World”);



With that done, you should save it in its own directory. Be sure to name it with whatever follows “class” in the commands listed above. Doing this is vital to accomplishing the following step.

Compile Your Code

The commands you saved in the previous step are just strings of text before compilation. Compiling in Java is basically the act of turning code into executable programs. To achieve this you need a compiling tool. Luckily, the Java Development Kit we downloaded earlier comes with said tool. Simply enter “javac” into a Dos or Unix prompt, and the file you saved earlier should turn into a Java class file capable of being run. Now, you can move on to the final step of your introduction to Java programming.

Run Your Finished Program

Here is the moment you’ve been looking forward to. Open a Dos or Unix prompt, and type in: “java myfirstjavaprog”. The program you have been working on should load and display the message “Hello World!” Now that you have learned how to set up an environment, enter code, compile that code and run it, you now have the basics needed to get started on programming in Java. Congratulations!

To any entrepreneur, programming in any language can seem like a daunting task. Once you have the basics down, however, you will find that it is just a matter of getting started. By following the easily accessible steps in this article, you will familiarize yourself with Java programming and eventually have the ability to develop your own applications.
