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.
