5 Dr. V. Jeyakesavan: Summary 18 years experience as Software Engineer 12 years of teaching experience

6 Get started… Introduction Classes & Objects Garbage collection & other differences compared to C++ Inheritance

7 Logistics & Goals Interactive & enjoyable Classroom Call me as Jey – no formalities - Treat me like a friend & co-worker! Show & play with hands-on examples Enhance your Java skills and knowledge I do not know everything, but I do have resources to get answers Questions?

8 Advanced Topics TopicDescription Standard Template Library (STL)Complex Data Structures ExceptionsUnique mechanism to pass the control around & help in debugging RecursionCore CS concept – less about Java Applets, GUI based gamesEvent based programming Multi-threadingParallelization and Synchronization Design PatternsAdvanced Software Design concepts JUnit testingUnique testing ideas for Java programs JDBC connectivityDatabase connectivity GreenfootEnjoyable IDE to learn advanced Java RMI, Enterprise Java, JavaBeans, Java ServLets, Java Packages

9 C++ vs. Java: differences C++Java Write once, compile everywhere  unique executable for each target Write once, run anywhere  same class files will run above all target-specific JREs. No strict relationship between class names and filenames. Typically, a header file and implementation file are used for each class. Strict relationship is enforced, e.g. source code for class PayRoll has to be in I/O statements use cin and cout, e.g. cin >> x; cout << y; I/O input mechanism is bit more complex, since default mechanism reads one byte at a time ( Output is easy, e.g. System.out.println(x); Pointers, References, and pass by value are supported. No array bound checking. Primitive data types always passed by value. Objects are passed by reference. Array bounds are always checked. Explicit memory management. Supports destructors. Automatic Garbage Collection. Supports operator overloading.Specifically operator overloading was left out.
