C is normally faster than Java, if it is written efficiently, but it always depends on the compiler. Some compilers support optimization on the compile time, to produce more efficient code, by removing redundant code and other unnecessary artefacts.

How fast is C compared to Java?

Based on these results, C is 2.34 times slower than Java and Python is 33.34 times slower than Java.

Why C program is faster than Java?

C is a procedural, low level, and compiled language. Java is an object-oriented, high level, and interpreted language. Java uses objects, while C uses functions. 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.
