Well as Bjarne Stroustrup says \\\"..despite the syntactic similarities, C++ and Java are very different languages. In many ways, Java seems closer to Smalltalk than to C++..\\\". Here are few I discovered:
• Java is multithreaded
• Java has no pointers
• Java has automatic memory management (garbage collection)
• Java is platform independent (Stroustrup may differ by saying \\\"Java is a platform\\\"
• Java has built-in support for comment documentation
• Java has no operator overloading
• Java doesn’t provide multiple inheritance
• There are no destructors in Java
