JDK Installation

Jul 04, 2019. Apache NetBeans provides editors, wizards, and templates to help you create applications in Java, PHP and many other languages. Cross Platform Apache NetBeans can be installed on all operating systems that support Java, i.e, Windows, Linux, Mac OSX and BSD. 2.1 Installing the Java Development Kit. The most complete and up-to-date versions of the Java Development Kit (JDK) are available from Oracle for Linux, Mac OS, Solaris, and Windows. Versions in various states of development exist for many other platforms, but those versions are licensed and distributed by the vendors of those platforms.

The JDK installation file can be obtained from the Oracle website withdownload page:
http://www.oracle.com/technetwork/java/javase/downloads (look for Java SE version 8)
The installation is simple: open the .dmg installationfile and click on the .pkg file within.Verify the installation by opening the Terminalfrom the System Utilities, and at the terminal prompt type:to verify that the correct JDK version is in use.

Netbeans Installation

NetBeans is Oracle's community-based Integrated Development Environment (IDE) for a variety of software development interests including Java, Php, C/C++, etc.It requires a JDK installation. The home and download pages are these:

The download link on the home page currently points to Apache/NetBeans, version 10.0.

The download I prefer is:

Forcing NetBeans to use JDK1.8

NetBeans on MAC OS X uses a version of JDK in some non-explicit way,and it's not always what you want. Usually it's based onthe the most recent JDK installation.So if you installed JDK 11, NetBean8.2 will not work withoutmaking the configuation file edit suggested in this site:Open a terminal shell and execute this command:You'll get a listing of all installed JDKs; look for JDK 8 installations ('Java SE 8'). If you don't have one,then download a JDK 8 version and install it. EachJDK versionshould have an associated JDK home directory, which we'll assume the one corresponding to jdk1.8.0_

Personalize NetBeans

I recommend spending some time personalizing NetBeans' settings.

Author and License

NetBeans automatically adds some level of documentation to Java (and other types of) filesit generates; in particular Licensing and Author information.The licensing information is not particularly revelant to our needs,but setting the user name is important.
  1. Set the user name which will be generated automatically in every class file.Go to Tools ⇾ Templates ⇾ Settings.Edit the file, setting the 'user' variable.
  2. Next, get rid of the Licensing information.Go to Tools ⇾ Templates ⇾ Licenses.Save the current 'Default License' by clicking on it andselecting Duplicate, thereby creating a copy Here is the current content of the license file:DO NOT DELETE THIS FILE!Simply select the content and delete it, or replace itby something more meaningful to you.

  4. In the left-hand window there you can observe three views ofthe netbeans contents: Projects, Files, Services. For the most part you can work from the Projects view. In the Projects window you willsee the file HelloWorld.java as part of the automatically-created helloworld package.
  5. Go to the Files view and observe the structure which NetBeans creates. The src folder ismeant to hold all the source packages.The HelloWorld.java file is in a package directory HelloWorld within the src folder.

  6. Within the public static void main function, typeObserve the various syntactic assists which the editor offerswhen you pause after typing a '.'.
  7. Select File ⇾ Save (or Ctrl-S) to save.
  8. There are several ways to compile and run this application.One way is to right-click on HelloWorld.java and select Run File fromthe popup menu. Look forthe output in the Output window at the bottom.

  9. Another way to build and run the project is by selecting Run ⇾ Cean and Build Projector Shift+F11. This operation goes a step further and archives the compiledclasses into the jar file HelloWorld.jar found in the newly created dist directory.Afterwards, select Run ⇾ Run Project or F6, or the button.
