Get started… Introduction Classes & ObjectsGarbage collection & other differences compared to C++Inheritance

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

Advanced Topics Topic Description Standard Template Library (STL) Complex Data Structures Exceptions Unique mechanism to pass the control around & help in debugging Recursion Core CS concept – less about Java Applets, GUI based games Event based programming Multi-threading Parallelization and Synchronization Design Patterns Advanced Software Design concepts JUnit testing Unique testing ideas for Java programs JDBC connectivity Database connectivity Greenfoot Enjoyable IDE to learn advanced Java RMI, Enterprise Java, JavaBeans, Java ServLets, Java Packages

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 PayRoll.java 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 (System.in). 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.
