A good answer might be:

Step 5: Save

Step 5: Save the Program

The next step is to save the characters in Notepad to a source file.

The file should be given the name that is the same as the class that contains the "main" method. Our first programs will contain only one class, so use that class name. The last part of the file name should be ".java" (don't forget the period.) Here is the start of this step:

You will get a window that allows you to "navigate" to the subdirectory where the file should be saved.

For this example, the subdirectory is C:\Temp. If you see this directory, click on it. (If you don't, use the various controls to move around until you do see it.) There will probably be miscellaneous strange files in this directory, but they don't hurt.

Type in the name of the source file: 

"HelloPlanets.java"

in the "File Name" text box. In some versions of Notepad you must use quote marks around the name of the file. Now Select "All Files" in the "Save as Type" text box. Finally, click on the "Save" button.

QUESTION 9:

Hopefully, the file "HelloPlanets.java" has been saved to the subdirectory C:\Temp, the same one that the DOS window is using. How can you confirm that this indeed happened?
