| Virtual Keyword | No. Java has no virtual keyword. We can override all non-static methods by default. In other words, non-static methods are virtual by default. | Yes. C++ supports virtual keyword so that we can decide whether or not override a function. |
| Unsigned right shift >>> | Yes. It fills zero at the top for the negative numbers. For positive numbers, it works same like >> operator. | No. |
| Inheritance Tree | Uses single inheritance tree because all classes are the child of object class in java. | Create a new inheritance tree always. |
| Hardware | Java is not so interactive with hardware. | C++ is nearer to Hardware. |
