Java Programming on NetBeans IDE

We have learnt how to execute a simple Java program in a command prompt. But most of the people freak out at the thought of the “black screen” and the trouble of remembering the commands!!!

I have a solution for them here – NetBeans.

What is NetBeans?

NetBeans is a software that allows you to run Java programs and build Java application in a more graphically presentable and easy-to-use environment. Technically speaking it is an Integrated Development Environment (IDE) which serves as a platform for Java programming, Java Stand-alone Application development, Web Application, Enterprise Applications and many more.

Here we will just focus on how to run a java program using NetBeans.

What is an IDE?

IDE or Integrated Development Environment is a software application that can be used by programmers for software development. The main advantage of using an IDE is that it can integrate the different units of an application to be developed and also helps integrating different tools required for the purpose.

The most popular IDEs for Java Application development are NetBeans and Eclipse. Here we going to work on it and am sure you won’t find the other IDEs much too different. So let’s get started!

Steps to write a program in NetBeans

  • Installing
    • Java Development Kit (JDK) should be installed in the system
    • NetBeans IDE should be installed

[Both are available online for download]

After installing these we will find the NetBeans IDE icon like this:

Java Programming on IDE

NetBeans IDE

The version can be newer that the one shown, like 7.2 or 7.3.

  • Creating a project
    • Open the IDE
Java Programming on NetBeans IDE

NetBeans Window

  • Go to the File menu at the top left corner of the screen.
  • Select the New Project option:
Opening Java Project in NetBeans

Opening Java Project in NetBeans

  • New Project dialog box appears. Select Java under ‘Categories’ and Java Application under ‘Projects’. Click the next button:
Opening Java Project in NetBeans

Opening Java Project IDE

  • New Java Application dialog box appears. Here we have to enter the Project Name. Let it be ‘FirstProg’. The location of the project can be browed and selected. Here we keep the default location. And the name of the project is set as the name of the java file we are creating by default. For the time being we need not worry about any more details and just click the Finish button:
Opening Java Project in IDE

Opening Java Project in IDE

  • FirstProg will appear under the Projects tab:
New Java Project

New Java Project

As we can see that under the FirstProg project there is a folder named ‘Source Packages’ and inside it is the package named ‘firstprog’ and inside it the FirstProg.java file where we are going to write the program. Package is a collection of distinct java classes i.e. no to class can have the same name within the same package.

On the right-hand side of the window appears the coding tab with the title FirstProg.java. We can see that NetBeans has already provided the program layout. The package name in which the file exists has to be specified at the very beginning as – package firstprog;

Just below the Projects tab is the Navigator tab where the different methods in a class are listed. We can move to the different parts of the program using this.

And below the program is the Output window where the result will be displayed after running the program.

  • Writing a program

The program is same as we had done using the Notepad and run in the command prompt in the previous lesson. The only difference is that we have to write less here since the structure of the program is already given and whenever there is an error it is notified to you using a red curvy line.

                package firstprog;

class FirstProg {

                public static void main (String args []){

                                System.out.println (“Hello World”);

                                }
}

Hello World Java Program

Hello World Java Program

  • Executing
    • Go to the Run option in the menu bar.
    • Click on the Compile option:
Compiling Java Program

Compiling Java Program

Compiled Java Program

Compiled Java Program

  • If the program is compiled successfully click on the Run File option again under the Run menu as shown in the figure above. The output is displayed in the output window:
Output Java Program

Output Java Program

Thus we have successfully executed the ‘Hello World’ program using a IDE in a more easy way. By learning to use NetBeans to execute a simple Java program we have actually took the first short step in building a Java Application in future!!!

    Hi Desbasmita,

    Wow, this is really technical for someone like me 🙂 Technical stuff is always scary for someone who’s not techy, you know.

    Anything Java is a bit like Greek to me. Recently I had people telling me that they couldn’t comment on my blog because they were getting a Java Script error message, but unfortunately, I wouldn’t be able to help them as I have no idea what it mean.

    If you could give me some light on that, that would be great.

    Thanks for the detailed information.

    Hey Sylviane…

    Firstly thanks a lot for visiting our blog and leaving a comment…:)

    Let me tell you that Java and Java Script are different things. Java Script is a scripting language to add more functionalities to HTML pages and make it more interactive.

    A website having Java Script will not work properly when one try to open it with a browser in which Java Script is disabled in the browser settings.

    So you can ask your readers to either open your website with a different browser, or enable Java Script in the settings (Content Settings) of the browser they are using.

    Its a pleasure that you asked my help in sorting your problem. Hope this information will help you…:)

    Thanks and hope to see you again!!!

    I’ve never ventured into Java myself, but with that clear explanation I can quite see how someone would be able to do so.

    You have a good and useful site. I’m sure it will find plenty of followers.

    Hi Debasmita

    You got it right, I hate command prompt due to its background, it makes it look old schools like operating on old windows
    I’m a dummy in the aspect of programming and coding, particularly java andd I guess I need to put more effort and try focusing on Netbeans. Well this is a great and epic tutorial and I’m glad I found this blog. Css and html haven’t been that problematic but php is my worst enemy, I’m sure I’ll definitely get helpful tutorials from S4C.
    Have a great week ahead.

    Hi Debasmita ,

    It is good that you show each step to explain. I have never used netbeans for developing Java. So It is very helpful for me to use netbeans.

    Thanks and keep going …!
