running a project with the ambient perspective
Before submitting a project as final, you
should always make sure it runs. For a project to be able to run, at
least one of the classes will have to have a main method. Now all you
have to do is select the dropdown menu with the icon 
and
choose Run Application (or whichever type of program you are
working on). Depending on the type of the application, you will either
see a new window pop up, or you will see some output in the console
window (bottom right).
console window
The console
window will show you all output generated by your program. If you
double-click on the console window title bar, you will maximize the
size of the window. Another double-click will return it to its original
size. Moreover, the window will also allow you to input information.
Simply click in the window and start typing. When the program is
finished, it will display the word terminated in the
window title bar. If your program is stuck or you would like to
terminate it for another reason, you can right-click in the console
window and select terminate.
multiple main methods
You may
have multiple classes with main methods in the same project. Java can
only run one main method at a time. If you select a project that
contains multiple main methods, you will be prompted to select which
one you would like to run.
