How to replace an element in a java.util.List with an element of another type?

Question

I have a list (java.util.list) . Now I want to replace elements in list<A> based on two conditions.

If element == 'a' replace with 'x' and if element == 'b' replace with 'y'. x and y are of type Q.

What is the cleanest / efficient way to do this? Preferably, I do not want to iterate using a for loop. I can use a stream/replaceAll but that would mean violating the type of the list.

Please be more specific. Generally, the approach is to transform the entire List into a List<A> or similar. — chrylis -cautiouslyoptimistic-

the whole of elements you have are either =a or =b? if it is not in this way , perhaps you have to use a generic list — tino89

I figured it out. I can use (pseudocode) (list<A>).stream().forEach(r->{condition?list.add(x):list.add(y)})

init list before this.
