What is the difference between Java and C
Java is an object-oriented programming language, while C++ is a multi-paradigm programming language. Java is a simpler language, designed to be smaller, more concise, and more portable than C/C++. It evaluates code at runtime and is easier to debug, making it great for large-scale projects. C++, on the other hand, is a lower-level language and includes more complex code than Java. It has more control over memory, making it potentially faster and more optimized than Java, but with the added complication of having to handle memory allocation manually.
