Java vs C

On real world and real application C++ is still usually faster than java , mainly because of lighter memory footprint that result in better cache performance.7 Kas 2011

Speed and performance Java is a favorite among developers, but because the code must first be interpreted during run-time, it’s also slower. C++ is compiled to binaries, so it runs immediately and therefore faster than Java programs .

Java is easier to learn and use because it’s high level, while C can do more and perform faster because it’s closer to machine code.

When it comes to system programming and/or other low-level applications, C++ is more powerful . Some people might argue that having automatic GC collections, no pointers, no multiple inheritances make Java more powerful. But when it comes to speed, C++ is powerful.
