Display style or format differences
Alice allows three different display styles or formats.
Two are identified as Java styles and one is identified as Alice style.
With the Alice style, the default method is named my first method.
With the two Java styles, the default method is named my_first_method because the Java format doesn't allow spaces in method names.
You will see other differences as well.
I recommend that you use one of the Java
styles to better prepare you for a transition later into Java, C#, or C++.
