'while' loop can be replaced with enhanced 'for' loop

Reports while loops that iterate over collections and can be replaced with enhanced for loops (foreach iteration syntax).


Iterator it = c.iterator(); while(it.hasNext()) { Object obj =; System.out.println(obj); }

Can be replaced with:

for (Object obj : c) { System.out.println(obj); }

This inspection only reports if the language level of the project or module is 5 or higher.
