Netbeans Ide Java Quick Start Tutorial

In this Java tutorial, we’re going to show you how to create your first Java acara using NetBeans – the official IDE for Java 8. NetBeans is a free and open source Java IDE.

You will be guided to download and install NetBeans IDE. Then create a Java project and write some Java code to print “Hello World” and run the program.

Before installing NetBeans IDE, make sure you installed Java Development Kit (JDK) on your computer first. If not, follow this tutorial to install JDK.

1. Download and Install NetBeans IDE

Go to https://netbeans.org/downloads to download the latest version of NetBeans IDE. You will see the following page:

NetBeans download page

On this download page you see different download bundles. And for Java development only, we can choose either Java SE or Java EE. We’d recommend you to choose Java EE which supports comprehensive Java development (Java EE includes Java SE).

So click the
Download
button in the column
Java EE
to download NetBeans installer for Java EE development. The file name of the installer program is something like
netbeans-8.2-javaee-windows.exe
(on Windows).

Click on the installer file to start installing NetBeans IDE. You will be asked to install GlassFish and Apache Tomcat peladen:

Install NetBeans choose servers

In this tutorial, you don’ufuk need any server. However you will need them later so let check both, and click
Next.

In the next screen, check ‘I accept the terms in the license agreement’:

Install NetBeans accept license

Click
Next.

In the next screen, choose the installation directory and JDK version for the IDE:

Install NetBeans choose directory and JDK

You can keep the defaults and click
Next.

In the next screen, choose installation directory and JDK version for GlassFish server:

Install NetBeans GlassFish

Click
Next
to see the summary:

Click
Finish.

Now you can start NetBeans IDE from the start menu. The splash screen appears:

2. Create Your First Java Project

Now, let’s create a Java project using NetBeans IDE. Go to menu
File > New Project…

Under the
New Project
dialog, choose Java application as shown in the following screenshot:

New Java Project

Click
Next
to advance to the next step. In the
New Java Application
screen, type Project Name, specify Project Location and the main class:

New Java Application

Note that we check the option
Create Main Class
to generate the main class for the application. Here we specify the package name
net.codejava
before the class name
HelloWorld.

Click
Finish. NetBeans create the project with a main class very quickly:

3. Write Your First Java Code

You can see a code pengedit for the
HelloWorld.java
file as shown in the following screenshot:

HelloWorld code generated

The method
main()
is the main entry to a Java application. All Java programs berangkat from the
main()
method. Now, let’s type some code in this method to print “Hello World Java!” on the screen:

System.out.println("Hello World Java!");

The whole program should look like this:

Hello World program

NetBeans is very smart, as it compiles the code instantly while you are typing the code. So if there’s any error, the IDE will inform you by underling the errors with red color, as shown in the following screenshot:

java compile error

If there’s no red marks like this, the code is fine and we’re ready to run the program.

4. Run Your First Java Program

To run the
HelloWorld
program above, there are several ways:

  • Go to menu
    Run > Run Project <ProjectName>
  • Click
    Run Project
    icon in the toolbar.
  • Press
    F6
    key.
  • Right click in the code editor, and select
    Run File
    (or press
    Shift + F6).

You should see the output of this programa like this:

Run Java Program Output

You see, it prints “Hello World Java!”. Congratulations, you have successfully created and run your first Java programa with NetBeans IDE. You can modify the program and run again to experiment more.
