Exercise 8.1: Building and running CommandLine sample program

Introduction:

In this exercise, you are going to build and run a sample Java program called CommandLineusing NetBeans. The sample program can be built and run as NetBeans project. So you are going to open an existing NetBeans project rather than creating a new project. (This is a similar setup as in Exercise 4.4 and Exercise 4.5 above.)

Steps to follow

0. If you have not downloaded and unzipped the NetBeansFiles.zip file as described above, please do that first.
1. Start NetBeans (if you have not done so.)
2. Open an existing CommandLine sample NetBeans project.

* Click Open Project Folder button.
* Expand CommandLineProject project node.
* Expand Source Packages. (The Source Packages node contains all the packages.)
* Expand . (If you create Java code without a package statement, it belongs to a default package.)
* Double click CommandLine.java to open it in the Editor window.

3. Add command line arguments

* Right click CommandLineProject project node and select Properties. Project Properties dialog box appears.
* In the Project Properties dialog box,
