[Performance] - foreach

Reports for loops which iterate over collections or arrays, and can be replaced
with the foreach iteration syntax, available in Java 5 and newer. These loops
generally can be replaced with the foreach loops, unless they modify underlying
list in the process, e.g. by calling list.remove(index). If latter is the case,
foreach form of loop may throw ConcurrentModificationException. This
avoids the creating of foreach loop variables of type java.lang.Object and
casts by the quickfix
