Which is faster C or Java or Python?

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 generally faster and more efficient than Python because it is a compiled language. As an interpreted language, Python has simpler, more concise syntax than Java. It can perform the same function as Java in fewer lines of code.

Java is much faster than Python in terms of speed of execution but slower than C++ . Every bit of code(variables and functions) has to be inside the class itself. Python has a huge set of libraries and modules. Code length is lesser than Java, around 1.5 times less.

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

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.
