Doubt inside the for loop

#1

why we use rrs here like for (string rrs : rr)

Java also includes another version of for loop introduced in Java 5. Enhanced for loop provides a simpler way to iterate through the elements of a collection or array. It is inflexible and should be used only when there is a need to iterate through the elements in sequential manner without knowing the index of currently processed element.
Also note that the object/variable is immutable when enhanced for loop is used i.e it ensures that the values in the array can not be modified, so it can be said as read only loop where you can’t update the values as opposite to other loops where values can be modified.
Syntax:

for (T element:Collection obj/array)
{
statement(s)
}
