Here's what I've learned over 20 years of working with both C++ and Java (and more years before that with C++): As a rule of thumb, when you convert optimized C++ to Java, the code is about 3x ...

C++ precompiled headers are compiler- and platform-specific. And C++ requires a large amount of source to be shipped in order to compile against it. Java defers platform-specific stuff to the runtime.

The C language has been a programming staple for decades. Here’s how it stacks up against C++, Java, C#, Go, Rust, Python, and the newest kid on the block—Carbon.

Java vs. C++ performance. In contrast, a program written in C++ gets compiled directly into machine code -- without an intermediary translation required at runtime. This is one reason why C++ programs ...
