The second button panel includes some different display options for the Code Editor view. The third
panel includes a bug icon for debugging your programs, a green play button for running your pro-
grams, and one other button for running external tools. The first two, debug and run, are most use-
ful at this point. This panel is shown in Figure 3-19.

Five more buttons that you might find useful are in the next two panels, shown in Figure 3-20. The
new package button has an icon that matches the package icon in the Project Explorer, which is a
small brown square with a cross through it. Next to it is a green circle with a C and a plus sign; this
is a shortcut to create a new class. You can change it from a class to another type with the drop‐
down arrow beside it. The yellow folder with a blue ball and a green ball is for opening classes (or
other types). If you are using the IDE for Java Developers, there's a yellow folder with a white box
in it; this is for opening a task. Finally, there is an icon of a yellow flashlight, which opens the search
window.

Now that you've had a tour of Eclipse, you're prepared to continue with the rest of this topic. In the
following chapters, there will be many exercises to demonstrate Object‐Oriented Programming con-
cepts in Java. They are written with the Eclipse IDE in mind, so you can refer back to this chapter if
you need a refresher on some of the basic technical aspects of creating programs in Eclipse. You can
also find a wealth of resources online from Eclipse if you're having trouble with something. Also, as
stated earlier, if you prefer to use another development environment, you will still be able to follow
along, but the instructions intended for Eclipse won't exactly match your IDE. The many platforms
available, including NetBeans and IntelliJ IDEA as well as many others, are often similar enough
that you can easily adapt from one to the other.
