Why doesn't java.util.Set have get(int index)?

Question

I\'m sure there\'s a good reason, but could someone please explain why the java.util.Set interface lacks get(int Index), or any similar get()

Answer 1

The only reason I can think of for using a numerical index in a set would be for iteration. For that, use

for(A a : set) { 
   visit(a); 
}
