Is Java based on C++?

As Java was inspired by C and C++, its syntax is similar to these languages. C++ is both a procedural and object-oriented programing language. Hence, C++ has features specific to procedural languages as well as features of object-oriented programming language. Java is a completely object-oriented programming language.

Why is Java slower than C?

Java is slow because it is a language that runs within a virtual machine, correctly written C will always be faster because it runs natively on the machine without the overhead of a virtual machine. Libraries are often written for “correctness” and readability, not performance.
