C++, it is a general purpose programming language. It has commanding, object-oriented and generic programming features. C++ provides facilities for the low-level memory operation.
Java, it is a general purpose computer programming language. It is synchronized, class-based, object-oriented and is precisely designed to carry out the least execution dependencies.
Both the languages, Java and C++ have been in production for years. There are many C++ programmers who say that it is easy to convert it into a Java project as the style and syntax of both the languages are similar. Java is an interpreted language- “write once, run anywhere”, whereas C++ is a compiled language. This is the dissimilarity that will play a huge role.
