Answer: Java:
There are no pointers.
There is no Operator Overloading.
There are no preprocessors.
There are no Structures and Unions.
There are no Enums.
There are no Functions (only methods within class).
There is no goto statement.(In java goto and const are reservedwords but Unused)
There are no Coercions(types should be converted explicitly)
There are no Global variables(variable is part of a class)
There are no Templates.(but in latest versions there are)
There are no default parameters.
There is garbage collection
There is multi-thread support.

C++:
There are pointers.
There is Operator Overloading
There are prepocessors.]
There are Structures and Unions.
There are Enums.
There are functions.
There is goto statement.
There are Coercions
There are Global variables
There are Templates.
There are default parameters.
There is no garbage collection.
There is support for multi-threading.

Java doesn't supports multiple inhertiance directly to avoid ambiguities.
Java does operator overloading implicitly on '+' for contatenation of strings only.
