4. Object-oriented: Java programming is an object-oriented programming language.Like C Java provides most of the object oriented features. Java is pure OOP Language. 5. Robust: Java encourages errorfree programming by being strictly typed and performing - run-time checks. There is lack of pointers that avoids security problem, automatic garbage collection,

Object oriented design methods emerged in the 1980s, and object oriented analysis methods emerged during the 1990s. In the early stage, object orientation was largely . and extensible system. Whole object oriented modeling is covered by using three kinds of models for a system description. These models are: object model,
method dispatch in different object-oriented programming languages. We also include an appendix on object-oriented programming languages, in which we consider the distinction between object-based and object-oriented programming languages and the evolution and notation and process of object-oriented analysis and design, start with Chapters 5 and 6;

Thermal system engineering is not usually thought of as a first rank engineering discipline as Mechanical, Civil, Electrical and Chemical Engineering, and it is usually ascribed to the leading one (like Aerospace, Naval, and Automotive Engineering) because the paradigmatic thermal systems has always been the heat engine, but its importance pervades all other branches (e.g. thermal control .
