Java & Dumb Code

>So clean, dumb code often runs faster than really clever code, contrary to what developing in C might have taught us. In C, clever source code turns into the expected idiom at the machine-code level, but it doesn't work that way in Java applications. I'm not saying that the Java compiler is too dumb to translate clever code into the appropriate machine code. It actually optimizes Java code more effectively than does C.

NO EXCEPTIONS

No-one in their right mind would listen to a java developer on the subject of code optimisation

Turns the string enclosed in single quotes  whereas escapeshellcmd just  does the escaping?
