However, the class diagram offers a prime example of the structure diagram type, and provides us with an initial set of notation elements that all other structure diagrams use. Imagine you could place two public classes in one file, then think about the work of the compiler: it has to build a .class file from your .java file that represents exactly one class (otherwise the .class ending wouldn't make any sense). As graphical representations of complex or simple problems and questions, decision trees have an important role in business, in finance, in project management, and in any other areas. This is just a start, and more sophisticated solutions do exist. The core concept of the object-oriented approach is to break complex problems into smaller objects. Here, let's try the one that generate code for the entire UML model. As you will see from the hierarchy diagram below, "Collection" is a root interface in the Collection hierarchy but "Collections" is a class which provide static methods to manipulate on some Collection types. Let’s explain decision tree with examples. Generate Java code from class diagram.
