How is Java's for loop code generated by the compiler

Question

How is Java\'s for loop code generated by the compiler?

For example, if I have:

for(String s : getStringArray() )
{
   //do something with s
}
         


        

Answer 1

Compiler might call it just once, but you can depend on it. It may not be a good coding practice. If getStringArray() returns same array each time, why not set to a variable first?
