| <div style="position:relative; left:38px; top:10px; width:380px;height:300px;font-size:16px;"> |
| The essence of object-oriented programming is to compose a system from a possibly large number of interacting classes and objects. |
| Since version 1.1, Java has not seen any enhancements for this task. |
| OT/J adds three closely related concepts: |
| <ul> |
| <li>Roles can be attached to a base object for dynamic specialization.</li> |
| <li>Roles are grouped into a Team to yield cohesive modules for use-cases & features.</li> |
| <li>Teams support nested inheritance for large-scale specialization.</li></ul> |

| <div style="position:relative; left:523px; top:-230px; width:245px;font-size:16px;"> |
| OT/J is agnostic to how algorithms are encoded (programming in the small), |
| but you may leverage lambda expressions from Java 8 in your OT/J programs for that touch |
| of functional programming. |

| <div style="position:relative; left:280px; top:-197px; width:450px;font-size:16px;"> |
| A rich type system is key for attaching semantics to the elements of your program. |
| <ul> |
| <li>Java 8 features …<br/> |
| type annotations for expressing more properties of types,</li> |
| <li>JDT leverages …<br/> |
| type annotations for detecting null related errors,</li> |
| <li>OT/J introduces …<br/> |
| dependent types to express object ownership.</li> |
| </ul> |
